John Calvin on Idols, Idolatry, Idolaters, & Faith

John Calvin's "Impiety of Attributing a Visible Form to God" from his work Institutes of the Christian Religion can be read here.

Also, read John Calvin's The Necessity of Reforming the Church here. In the short book, Calvin makes a good argument why Christians shouldn't turn a blind eye to idolatry.

A quote from Calvin's book:

We know how execrable a thing idolatry is in the sight of God, and history abounds with narratives of the dreadful punishments with which He visited it, both in the Israelitish people and in other nations. From his own mouth, we hear the same vengeance denounced against all ages. For to us he speaks when he swears by his holy name, that he will not suffer his glory to be transferred to idols, and when he declares that he is a jealous God, taking vengeance, to the third and fourth generation, upon all sins, and more especially on this one. This is the sin on account of which Moses, who was other wise of so meek a temper, being inflamed by the Spirit of God, ordered the Levites

“to go in and out from gate to gate throughout the camp, and slay every man his brother, and every man his companion, and every man his neighbor,” (Exodus 32:27;)

the sin on account of which God so often punished his chosen people, afflicting them with sword, pestilence, and famine, and, in short, all kinds of calamity; the sin on account of which, especially, the kingdom, first of Israel, and then of Judah, was laid waste, Jerusalem the holy city destroyed, the temple of God (the only temple then existing in the world) laid in ruins, and the people whom he had selected out of all the nations of the earth to be peculiarly his own, entering into covenant with them, that they alone might bear his standard, and live under his rule and protection — the people, in short, from whom Christ was to spring, were doomed to all kinds of disaster, stript of all dignity, driven into exile, and brought to the brink of destruction. It were too long here to give a full detail, for there is not a page in the Prophets which does not proclaim aloud that there is nothing which more provokes the divine indignation. What then? When we saw idolatry openly and everywhere stalking abroad, were we to connive at it? To have done so would have just been to rock the world in its sleep of death, that it might not awake.

Calvin's commentary on Exodus 32:1
1. And when the people saw that Moses. In this narrative we perceive the detestable impiety of the people, their worse than base ingratitude, and their monstrous madness, mixed with stupidity. For their sakes Moses had been carried up above the state of terrestrial life, that he might receive the injunctions of his mission, and that his authority might be beyond the reach of controversy. They perversely declare that they know not what has become of him, nay, they speak contemptuously of him as of a person unknown to them. It is for this that Stephen severely blames them, This is that Moses (he says) whom your fathers rejected, though he was the minister of their salvation. (Act_7:35.) They confess that he had been their deliverer, yet they cannot tolerate his absence for a little time, nor are they affected with any reverence towards him, unless they have him before their eyes. Moreover, although God offered Himself as if present with them by day and by night in the pillar of fire, and in the cloud, they still despised so illustrious and lively an image of His glory and power, and desire to have Him represented to them in the shape of a dead idol. For what could they mean by saying, “make us gods which shall go before us?” Could they not see the pillar of fire and the cloud? Was not God’s paternal solicitude abundantly conspicuous every day in the manna? Was he not near them in ways innumerable

Yet, accounting as nothing all these true, and sure, and manifest tokens of God’s presence, they desire to have a figure which may satisfy their vanity. And this was the original source of idolatry, that men supposed that they could not otherwise possess God, unless by subjecting Him to their own imagination. Nothing, however, can be more preposterous; for since the minds of men and all their senses sink far below the loftiness of God, when they try to bring Him down to the measure of their own weak capacity, they travesty Him. In a word, whatever man’s reason conceives of Him is mere falsehood; and nevertheless, this depraved longing can hardly be repressed, so fiercely does it burst out. They are also influenced by pride and presumption, when they do not hesitate to drag down His glory as it were from heaven, and to subject it to earthly elements. We now understand what motive chiefly impelled the Israelites to this madness in demanding that a figure of God should be set before them, viz., because they measured Him by their own senses. Wonderful indeed was their stupidity, to desire that a God should be made by mortal men, as if he could be a god, or could deserve to be accounted such who obtains his divinity at the caprice of men. Still, it is not probable that they were so absurd as to desire a new god to be created for them; but they call “gods” by metonymy those outward images, by looking at which the superstitious imagine that God is near them. And this is evident from the fact, that not only the noun but the verb also is in the plural number; for although they were satisfied with one God, still they in a manner cut Him to pieces by their various representations of Him. Nevertheless, however they may deceive themselves under this or that pretext, they still desire to be creators of God.

Those who suppose that confusion is implied by the word “delayed,” are, in my opinion, mistaken; for, although the word בשש, boshesh, with its third radical doubled, is derived from בוש, bush, which means to be ashamed, still it is clear from Jud_5:28, that it is used simply for to delay, where it is said, in the address of the mother of Sisera, “Why does his chariot delay (or defer) to come?”

Hence we may understand that hypocrites so fear God as that religion vanishes from their hearts, unless there be some task-master (exactor) standing by them to keep them in the path of duty. They duly obeyed Moses and reverenced his person; but, because they were only influenced by his presence, as soon as they were deprived of it they ceased to fear God. Thus, whilst Joshua was alive, and the other holy Judges, they seemed to be faithful in the exercise of piety, but when they were dead, they straightway relapsed into disobedience.
Calvin's commentary on Exodus 32:4:
4. And he received them at their hand. He briefly narrates this base and shameful deed; yet sufficiently shows, that whilst Aaron yielded to their madness, he still desired to cure it, though, at the same time, he was weak and frightened, so as to pretend to give his assent, because he feared the consequences of the tumult as regarded himself. For why does he not command the ear-rings to be thrown into some chest, lest he should pollute himself by the contagion of the sacrilege? Since, therefore, he received them into his own hands, it was a sign of a servile and effeminate mind; and thus he is said to have been the founder, or sculptor of the calf, when it is nevertheless probable that workmen were employed upon it. But the infamy of the crime is justly brought upon him, inasmuch as he was its main author, and by his guilt betrayed the religion and honor of God.

The Hebrew word חרט, cheret, some translate a stylus or graving-tool, some a mould; the former think that the rough mass was formed by sculpture into the shape of a calf; the latter, that the calf was cast or founded; as we say, jetter en mousle, to cast in a mould. Ridiculous, however, is the fable, that when the gold was thrown into a furnace, it came forth like a calf without human workmanship; but thus licentiously do the Jews trifle with their fond inventions. The more probable conjecture is, that Aaron designedly sought a remedy for the people’s folly.

It was a disgraceful thing to prostrate themselves before a calf, in which there was no connection or affinity with the glory of God; and with this the Prophet expressly reproaches them, that “they changed their glory (i. e. , God, in whom alone they should have gloried) into the similitude of an ox that eateth grass.” (Psa_106:20.) For, if it be insulting to God to force Him into the likeness of men, with how much greater and more inexcusable ignominy is His majesty defiled, when He is compared to brute animals? Still it had no effect towards bringing them to repentance; and this is expressed with much force immediately afterwards, when they said to each other, “These be thy gods, O Israel.” Surely the hideousness of the spectacle should have struck them with horror, so as to induce them voluntarily to condemn their own madness; but, on the contrary, they mutually exhort one another to obstinacy; for there is no doubt but that Moses indicates that they were like fans to each other, and thus that their frenzy was reciprocally excited. For, as Isaiah and Micah exhort believers, that each of them should stretch out his hand to his brother, and that they should say to each other,

“Come ye, and let us go up to the mountain of the Lord;” (Isa_2:3; Mic_4:2;)

thus does perverse rivalry provoke unbelievers mutually to excite each other to progress in sin. Still they neither speak ironically nor in mockery of God, nor have any intention of falling away from Him; but they cover their sin against Him under a deceitful pretext, as if they denied that by their new and unwonted mode of worship, they desired to detract from the honor of their Redeemer; but rather that it was thus magnified because they worshipped Himself under a visible image. Thus now-a-days do the Papists boldly obtrude their fictitious rites upon God; and boast that they do more for Him by their additions and inventions than as if they merely continued within the bounds prescribed by Himself. But let us learn from this passage, that whatever colouring superstition may give to its idols, and by whatever titles it may dignify them, they remain idols still; for, however those who corrupt the pure worship of God by their inventions, may pride themselves on their good intentions, they still deny the true God, and substitute devils in His place.

Their conjecture is probable who suppose that, Aaron devised the calf in accordance with Egyptian superstition; for it is well known with what senseless worship that nation honored its god Anubis. It is true that they kept a live bull to be consulted as the supreme god; but, inasmuch as the people were accustomed to this fictitious deity, Aaron seems in obedience to their madness to have followed that old custom, from whence they had contracted the error, which was so deeply rooted in their hearts. Thus from bad examples does contagion easily creep into the hearts of those who were else untainted; nor is it without good reason that David protests that idols should be held in such abomination by him, that he would not even “take up their names into his lips,” (Psa_16:4;) for, unless we seriously abhor the ungodly, and withdraw ourselves as far as possible from their superstitions, they straightway infect us by their pestilential influence.
Calvin's Commentaries, Vol. 4: Harmony of the Law, Part II, tr. by John King, [1847-50], at sacred-texts.com. Calvin's commentary on Exodus 34:17:
Exodus 34:17. Thou shalt make thee no molten gods. When he calls graven things, statues, and pictures, by the name of gods, he shews the object and sum of the Second Commandment, viz., that God is insulted when He is clothed in a corporeal image. Moreover, the name of God is transferred to idols, according to common parlance, and the corrupt opinion of the Gentiles; not that unbelievers thought that the Deity was included in the corruptible material, but because they imagined that it was nearer to them, if some earthly symbol of its presence were standing before their eyes. In this sense, they called the images of the gods their gods; because they thought they could not ascend to the heights in which the Deity dwelt, unless they mounted by these earthly aids. There is no doubt but that he comprehends by synecdoche, all kinds of images, when he forbids the making of molten gods; because metal is no more abominated by God than wood, or stone, or any other material, out of which idols are usually made; but, inasmuch as the insane zeal of superstition is the more inflamed by the value of the material or the beauty of the workmanship, Moses especially condemned molten gods. All question on this point is removed by the fourth passage here cited, wherein the Israelites are forbidden to make gods of silver or gold, viz., because idolaters indulge themselves more fully in their worship of very precious idols, by the external splendor of which all their senses are ravished. To the same effect is the third passage, in which mention is not, only made of graven images, but there is also added the name of a statue 89 or figured stone; for, although some expound these words as referring to a pavement, yet I have no doubt but that all monuments are included in them, wherein foolish men think that they have God in some measure visible, and therefore that they express all sculptures and pictures by which the spiritual worship of God is corrupted. For the object of Moses is to restrain the rashness of men, lest they should travesty God’s glory by their imaginations; for another clause is immediately added, “I am the Lord your God,” in which God reminds them that He is despoiled of His due honor, whenever men devise anything earthly or carnal respecting Him. The word מצבה, 90 matsebah, is sometimes used in a good sense; whence it follows, that no other statues are here condemned, except those which are erected as representations of God. The same also is the case as to the polished stone, 91 viz., when it receives a consecration, which may attract men’s minds to regard it in a religious light, so as to worship God in the stone. But both in the second and third passages, Moses teaches men that as soon as they imagine anything gross or terrestrial in the deity, they altogether depart from the true God. And this is also expressed in the word אלילים, elilim, which embraces in it statues, stones, and graven images, as well as molten gods. Some think that this word is compounded of אל, al 92 the negative particle, and אל, el, God. Others translate it “a thing of nought;” the Greeks and Latins have rendered it “idols.” It is plain, that the false representations, which travesty God, are so called to mark them with disgrace and ignominy. But, since the superstitious cease not to gloss over their errors with cavils, God is not content with this opprobrious name, but adds others also, respecting which their pretext was more specious; that we may know that whatsoever withdraws us from His spiritual service, or whatsoever men introduce alien from His nature, is repudiated by Him. In the fourth passage, the antithesis must be noted, which will presently be explained more fully, viz., when God forbids them to make gods of corruptible materials, since He has “spoken from heaven;” in which words He signifies that all are doing wrong, who, when they ought to look up to heaven, tie down their own minds as well as Him to earthly elements.
Calvin's Commentaries, Vol. 4: Harmony of the Law, Part II, tr. by John King, [1847-50], at sacred-texts.com. Calvin's commentary on Deuteronomy 4:12:
Deuteronomy 4:12. And the Lord spake unto you. It is a confirmation of the Second Commandment, that God manifested Himself to the Israelites by a voice, and not in a bodily form; whence it follows that those who are not contented with His voice, but seek His visible form, substitute imaginations and phantoms in His place. But here arises a difficult question, for God made Himself known to the patriarchs in other ways besides by His voice alone; thus Abraham, Isaac, and Jacob knew Him not only by hearing, but by sight. Moses himself saw Him in the midst of the burning bush; and He also manifested Himself to the Prophets under visible figures. Since it would be superfluous to heap together many citations, let the remarkable vision of Isaiah suffice, which is related in (Isa 6), and those of Ezekiel, which we read of in (Eze 1 and Eze 10) And yet God was not forgetful of Himself, when He thus presented Himself to the sight of His servants. Wherefore, this argument does not appear to be valid and good, that it is sinful to represent God in a visible image, because His voice was once heard without His being seen; when, on the other side, it is easy to object that visible forms have often been exhibited, wherein He testified His presence. The solution is twofold: first, that, although God may have invested Himself in certain forms for the purpose of manifesting Himself, this must be accounted as a peculiar circumstance, and not be taken as a general rule; secondly, that the visions shewn to the patriarchs were testimonies of His invisible glory, rather to elevate men’s minds to things above than to keep them entangled amongst earthly elements. In the promulgation of His Law, God first prescribed what believers must follow; because He saw that this was the best method (compendium) for retaining the minds of His people in true religion, and at the same time the best remedy for idolatry. Unless we submit to this counsel of God, we shall not only betray a licentious spirit of contention, but shall run directly against God, like butting bulls. For it was not in vain that Moses laid down this principle, that when God collected to Himself a Church, and handed down a certain and inviolable rule for holy living, He had not invested Himself in a bodily shape, but had exhibited the living image of His glory in the doctrine itself. Hence we may conclude that all those who seek for God in a visible figure, not only decline, but actually revolt, from the true study of piety.
If any one should object that God is not inconsistent with Himself, and yet, as has been said, that He has more than once taken upon Himself a visible form, the reply is simple and easy, that, whenever He appeared to the patriarchs in a visible form, He gave a temporary sign, which still was by no means contradictory of this commandment. Isaiah saw the Lord of hosts sitting on His throne; yet he boldly cries out as from the mouth of God, “To whom will ye liken me?” (Isa 40:25.) Nor need I repeat how constantly he speaks against idolaters; certainly he inveighs more strongly than any of the prophets against the folly, nay, the madness of those who make to themselves any image of God; because they thus turn truth into falsehood; and finally he assumes the same principle as that of Moses, that the true nature of God is corrupted by tricks and delusions if a corruptible thing be called His image. But what was His vision itself? The seraphim, who surrounded God’s throne, sufficiently shewed by their covering their faces with their wings that the sight of Him could not be borne by mortals. As to what Ezekiel relates, no painter could represent it; for God has always appeared distinguished from the shape of any creature by those marks which surpass man’s apprehension. This conclusion, therefore, always remains sure, that no image is suitable to God, because He would not be perceived by His people otherwise than in a voice. But then also fire was a symbol of His presence, yet He testified by it that His glory is incomprehensible, and thus would prevent men from idol-making. We have elsewhere explained what it is “to guard themselves as to their souls.” 93 But we infer, from his anxious exhortations, that they should take heed, how great is the leaning of the human soul to idolatry. This is the tendency of that attestation against them, which I have inserted from (Deuteronomy 8); for Moses not only threatens them, but, as if summoning witnesses according to the custom of solemn trials, denounces that they shall perish, in order to inspire them with greater fear by this earnest mode of address. Whence it appears that this insane lust (of idolatry) is not to be repressed by ordinary means. With the same object he says that they are “corrupted, or corrupt themselves,” who make any similitude of God. Thus Paul also declares that in this way the truth is changed into a lie, (Ro 1:25;) and Jeremiah and Habakkuk condemn images for their falsehood. (Jer 10:14; Hab 2:18.) No wonder, then, that an idol should be called the “corruption” of men, since it adulterates the worship of God; and it is a most just recompense to those who pollute the pure and perfect knowledge of God, that they should be thence infected with a rottenness which consumes their souls. Hence, also, the stupid ignorance of the Papists is confuted who confine this prohibition to the ancient people, as if it were now permitted to paint or to sculpture (images of God) 94 as if they had been Jews whom Paul was addressing, when he reasoned from the common origin of our nature: “Forasmuch as we are the offspring of God, we ought not to think that the Godhead is like unto gold or silver,” or corruptible matter. (Ac 17:29) 95 There is no necessity for entering into details; but the Spirit declares no less plainly now that we must keep ourselves from idols, (1Jo 5:21,) than He of old forbade their being made. Moreover, it was an act of diabolical madness to make away with one of the Ten Commandments, in order that they might rush into this foul and detestable extravagance with impunity. They pretend that the Jews were formerly prohibited from idolatry with greater strictness, because they were too much disposed to it, as if they were not themselves much worse in this respect. But, setting aside this, who does not see that the vice of superstition, which is natural to the human mind, was corrected by this remedy? Until, therefore, men have laid aside their nature, we infer that this Commandment is necessary for them.
Calvin's commentary on Deuteronomy 4:23:
23. Take heed unto yourselves, lest ye forget. There is no contradiction in the sense, that he should first of all altogether forbid that idols should be made; and, secondly, speak only of worshipping and adoring them; for it is already in itself a wicked error to attribute any image to God; and another superstition always accompanies it, that God is always improperly worshipped in this visible symbol. There is a strong confirmation here of what I have previously stated, that whatever holds down and confines our senses to the earth, is contrary to the covenant of God; in which, inviting us to Himself, He permits us to think of nothing but what is spiritual, and therefore sets His voice against all the imaginations, whereby heathen nations have always been deceived; because they have been deprived of the light of that doctrine which would direct them to the heavenly greatness of God Himself. But those who have been taught by God’s Law, not only that He alone is to be worshipped, but that He may not be represented by any visible effigy, are justly accounted covenant-breakers, if they do not confine themselves within these bounds; for they violate that Second Commandment (caput) by which they are commanded to worship God spiritually; and consequently are forbidden to make to themselves likenesses, or images, whereby they would deface and pollute His glory. At the end of the verse, which some translate “the likeness, which your God hath forbidden,” 99 the proper rendering is, “hath commanded, or enjoined:” and hence the relative אור, asher, must be taken, as in many other places, as an adverb of comparison. The meaning of Moses is indeed by no means obscure; viz., that we must simply obey God’s word; and that we must not dispute whether what He has forbidden is lawful or not; and that no other rule of right is to be sought for, except that we should follow what He has prescribed. Let the Papists dispute as they please, that images are not to be removed because they are useful for the people’s instruction; but let this be our wisdom, to acquiesce in what God has chosen to decree in this matter. Although the threat which is subjoined might have been placed amongst the sanctions, which we shall hereafter consider in their proper place, yet I have been unwilling to separate it from the Second Commandment, to which it is annexed. A confirmation is added in Deuteronomy; viz., that God, who has not spared foreign nations, will much less pardon His people; inasnmch as it is a greater crime, and fouler ingratitude to forsake God when once He is known, and to cast aside the teaching of His Law, than to follow errors handed down from our forefathers. I have already explained in what sense He is called a “jealous God;” but in Ex 34:14, Moses has not deemed it sufficient simply to honor God with this title; but, in amplification, he has added that this is His name, in order that we may know that He can no more bear a companion, or a rival, to be compared with Him, than He can cast away His Godhead, or deny Himself. He compares Him to fire, to increase our terror of Him. We know how audaciously the world indulges itself in superstitions; so that, as if in very sport, it metamorphoses God just as fancy leads. Wherefore, in order to incline men’s minds to reverence, he sets before us in this figure God’s fearful vengeance; as though He would instantly consume them, just as fire consumes stubble, if they shall have dared to think of God otherwise than is right.
Calvin's Commentaries, Vol. 15: Isaiah, Part III, tr. by John King, [1847-50], at sacred-texts.com. Calvin's commentary on Deuteronomy 16:22:

22. Neither shalt thou set thee up. Hence also it more clearly appears what is the meaning and tendency of the Second Commandment. God elsewhere commands, 100 (as we have seen,) that statues 101 should be erected on the borders of the land, on which the sum of the Law should be inscribed. At first sight this prohibition seems to be contradictory; and indeed it would be so, unless you understand “statue” to be a false image of God, in which men set Him before them in bodily form; and, therefore, it is added, that He hates such statues. But I have preferred translating 102 the relative in the neuter gender, that the sentence might be fuller; i.e., that the erecting of statues is an abomination to the Lord; because in this way His glory is dishonored, when He is transfigured into a body, or when anything corporeal is mixed with His spiritual nature.

Calvin on Psalm 83:18:
18.And let them know that thou art, thy name Jehovah. It is not the saving knowledge of God which is here spoken of, but that acknowledgement of him which his irresistible power extorts from the wicked. It is not simply said that they will know that there is a God; but a special kind of knowledge is laid down, it being intimated that the heathen who before held the true religion in contempt, would at length perceive that the God who made himself known in the Law, and who was worshipped in Judea, was the only true God. Still, however, it must be remembered, that the knowledge spoken of is only that which is of an evanescent character, having neither root nor the living juice to nourish it; for the wicked will not submit to God willingly and cordially, but are drawn by compulsion to yield a counterfeit obedience, or, being restrained by him, dare not break forth into open outrage. This, then, is an experimental recognition of God which penetrates not to the heart, but is extorted from them by force and necessity. The pronoun אתה, atah, thou, is emphatic, implying a tacit contrast between the God of Israel and all the false gods which were the product of men’s invention. The prayer amounts to this: Lord, make them to know that the idols which they have fabricated for themselves are no gods, and in fact are nothing. The despisers of God may indeed shun the light, and at one time may overcast themselves with clouds, while at another their may plunge into the deep and thick shades of darkness; but He pursues them, and draws them forth to the knowledge of himself, which they would fain bury in ignorance. And as the world indiscriminately and disgracefully applies his sacred name to its own trifling inventions, this profanation is corrected when it is added, thy name Jehovah. This implies that being, or really to be, is in the strict sense applicable to God alone; for although unbelievers may attempt to tear his glory to pieces, he continues perfect and unchanged. The contrast of which I have spoken, must be kept in mind by the reader. A nation has never existed so barbarous as not to have worshipped some deity; but every country forged particular gods for itself. And although the Moabites, the Edomites, and the rest of these nations, admitted that some power and authority belonged to the God of Israel, yet they conceived that this power and authority did not extend beyond the boundaries of Judea. Thus the king of Syria called him, “the God of the hills,” (1Kg_20:23.) This preposterous and absurd division of God’s glory, which men make, is disproved by one word, and all the superstitions which at that time prevailed in the world are overthrown, when the Prophet attributes to the God of Israel, as well the essence of Deity as the name; for unless all the idols of the heathen are completely abolished, he will not obtain, alone and unshared, the name of Jehovah. Accordingly, it is added, Thou alone art the Most High over all the earth; a statement which is worthy of our most careful attention. The superstitious commonly think it enough to leave God his name, that is to say, two or three syllables; and in the meantime they fritter away his power, as if his majesty were contained in an empty title. Let us then remember that God does not receive that honor among men to which he is entitled, if he is not allowed to possess his own inherent sovereignty, and if his glory is obscured by setting up other objects against him with antagonist claims.
Calvin's Commentaries, Vol. 11: Psalms, Part IV, tr. by John King, [1847-50], at sacred-texts.com. From Calvin's commentary on Psalm 106:
19. They made a calf. 250 Here he represents their rebellion as exceedingly base, in that they abandoned the true worship of God, and made to themselves a calf. For although it was their intention to worship God in this manner, yet the prophet reprehends their brutal stupidity, because they worshipped before the molten image, 251 and represented God by the figure of an ox which eateth grass 252 From this the prophet infers, that God had been robbed of his honor, and that all his glory had been tarnished. And surely it is so; for although the idolaters feign to serve God with great zeal, yet when, at the same time, they represent to themselves a God visible, they abandon the true God, and impiously make for themselves an idol. But he reproaches them with being guilty of still greater impiety, when he says, after the likeness of an ox that eateth grass; and contrasts with it their honor or glory. For seeing that God had clothed them with his own glory, what madness was it to substitute in place of him not only an ox, but the inanimate form of an ox, as if there were any resemblance between God who createth all kinds of food, and that stupid animal which feeds upon grass?

It is necessary, however, to observe the design of the prophet, which is to point out the blindness of men as more base and abominable, because not contenting themselves with any common form of superstition, but casting off all sham they give themselves up to the most shocking forms of worshipping God. Had the people formed for themselves a likeness of God under the likeness of a man, even that would have been impiously robbing God of his due; how much more shameful was their conduct when they assimilated God to an ox? When men preserve their life by eating and drinking, they acknowledge how frail they are, because they derive 253 from dead creatures the means of its continuation. How much greater is the dishonor done to God when he is compared to the brutal tribes? Moreover, the comparison referred to increases the enormity of their guilt. For what credit was it for a holy people to worship the inanimate likeness of an ox instead of the true God? But God had condescended to spread out the overshadowing wings of his glory upon the children of Abraham, that he might put on them the highest honor. Therefore, in denuding themselves of this honor, they had exposed their own baseness to the derision of all the nations of the earth. And hence Moses employs the phrase of nakedness, when he is showing that crime of idolatry:

“And when Moses saw that the people were naked, (for Aaron had made them naked unto their shame among their enemies)”
Ex 32:25.

...
21. They forgot God The prophet again repeats that the people had sinned not simply through ignorance, but also wilfully, inasmuch as God had already given a very palpable manifestation of his power and glory. And as he makes himself known in the creation of the heavens and of the earth, the blindness of men is totally inexcusable. But far more aggravating is the sin of the children of Israel, who, after God had made himself known to them, in the most condescending manner, cast him off altogether, and gave themselves up to the practice of brutish idolatry. And God having from heaven put forth his Almighty power for their salvation, there must surely be no little importance attached to such displays of his power as proclaim the praise and honor of his great name. Had he merely given an ordinary token of his power, even that ought to have attracted so much consideration as should have kept the people in the fear and worship of God. Now, that these miracles were so very notable, or rather terrible and rare, the people acted a very base part to shut their eyes upon them, and give themselves over to idolatry. For as the darkness is dispelled by the beamy lustre of the sun, so all inventions and perverse errors should vanish before such knowledge of God.
Calvin's Commentaries, Vol. 11: Psalms, Part IV, tr. by John King, [1847-50], at sacred-texts.com. From Calvin's commentary on Psalm 115:4-8:
If a man carve an image of marble, wood, or brass, or if he cast one of gold or silver, this of itself would not be so detestable a thing; but when men attempt to attach God to their inventions, and to make him, as it were, descend from heaven, then a pure fiction is substituted in his place. It is very true that God’s glory is instantly counterfeited when it is invested with a corruptible form; (“To whom hast thou likened me?” he exclaims by Isa 40:25, and Isa 46:5, and the Scripture abounds with such texts;) nevertheless, he is doubly injured when his truth, and grace, and power, are imagined to be concentrated in idols. To make idols, and then to confide in them, are things which are almost inseparable. Else whence is it that the world so strongly desires gods of stone, or of wood, or of clay, or of any earthly material, were it not that they believe that God is far from them, until they hold him fixed to them by some bond? Averse to seek God in a spiritual manner, they therefore pull him down from his throne, and place him under inanimate things. Thus it comes to pass, that they address their supplications to images, because they imagine that in them God’s ears, and also his eyes and hands, are near to them. I have observed that these two vices can hardly be severed, namely, that those who, in forging idols, change the truth of God into a lie, must also ascribe something of divinity to them. When the prophet says that unbelievers put their trust in idols, his design, as I formerly noticed, was to condemn this as the chief and most detestable piece of profanity.
Calvin's commentary on Isaiah 40:18:
When Paul employs this passage (Act_17:29) as a proof against idolaters, or at least quotes the words of the Prophet, he does not wrest them from their true meaning. He infers, indeed, from them that to frame any image of God is exceedingly wicked, while the Prophet, in guarding the Jews against distrust, at the same time condemns the superstitions of the Gentiles, and declares that it is inconsistent with the nature of God to be represented by painting or by any kind of likeness. This shews clearly that Paul’s doctrine fully agrees with it; for the Prophet, after having shewn that the power of God is infinite, since he holds all things in his fist, at length concludes, “To whom then will ye liken me? for no image that is formed will have any likeness or resemblance to me.”

Or, what resemblance will you appoint to him? This is a useful doctrine, and worthy of observation; for were there nothing more than this single passage, it would be perfectly sufficient for refuting the inventions by which Papists deceive themselves, when they think that they have a right to represent God by outward figures. The Prophet declares that it is impossible to frame out of dead matter an image which shall have any resemblance to the glory of God. He openly rejects idols, and does not even speak of the worship of them, but affirms that to manufacture and set them up before God is wicked and abominable. The Scripture is full of such proofs. Moses warned a people prone to this vice,

“Thou sawest no image or shape in the mountain, thou only heardest a voice. See then and beware that thou be not led astray so as to frame for thyself any image.”
(Deu_4:12.)

In order to know God, therefore, we must not frame a likeness of him according to our own fancy, but we must betake ourselves to the Word, in which his lively image is exhibited to us. Satisfied with that communication, let us not attempt anything else of our own. Other ways and methods, such as idols and images, teach us vanity and falsehood, and not truth, as Jeremiah beautifully says, “The wood is the instruction of vanities,” (Jer_10:8,) and Habakkuk, “His graven image is falsehood.” (Hab_2:18.) When the Lord sometimes compares himself to a lion, a bear, a man, or other objects, this has nothing to do with images, as the Papists imagine, but by those metaphors either the kindness and mercy of God, or his wroth and displeasure, and other things of the same nature, are expressed; for God cannot reveal himself to us in any other way than by a comparison with things which we know. In short, if it were lawful to frame or set up an image of God, that would be a point of resemblance to the gods of the Gentiles, and this declaration of the Prophet could not be maintained.

Calvin's commentary on Isaiah 40:20:
Men wish to enjoy the presence of God, and this is the beginning and source of idolatry; for God is not present with us by an idol, but by his word and by the power of his Spirit; and although he holds out to us in the sacraments an image both of his grace and of spiritual blessings, yet this is done with no other intention than to lead us upwards to himself.
Recall Exodus 32:1,
And when the people saw that Moses delayed to come down out of the mount, the people gathered themselves together unto Aaron, and said unto him, Up, make us gods [Elohim], which shall go before us; for as for this Moses, the man that brought us up out of the land of Egypt, we wot not what is become of him.
Calvin's commentary on Isaiah 40:25:
25.And to whom will ye liken me? He repeats the former statement, (Isa_40:18,) by which he said that the Lord would not suffer himself to be likened to idols; that the Jews might not in any degree detract, from his power, on account of their having been so long held captive in the hand of unbelievers, or think that idols are anything on account of the prosperity of their worshippers, whom they were compelled to serve; for, by reasoning in this manner about the power of the true God and of idols, they would have compared him with idols. On this account he repeats, as it were in indignation, “To whom will ye liken me?” as if he had said, “Will you rob me of my majesty by your comparisons?” For although men have various thoughts of God, and transform him according to their fancy, yet he continues to be like himself, for he does not change his nature on account of the inventions of men.

Saith the Holy One. He appropriately applies to God the term Holy, by which title he indirectly blames or accuses the Jews of base ingratitude, if, as they have been set apart by him, they do not sanctify him in return. No holiness will be found in the gods of the Gentiles; they are the mere inventions of men. A grievous injury therefore is done to God, and he is basely degraded from his rank, when idols are brought into collision with him, and when it becomes a subject of debate if they can do more than God himself.
Calvin's commentary on Isaiah 41:24:
He hath chosen abomination in you. Some translate abomination in the nominative case, and suppose the meaning to be, that the men who choose the idols are abominable; but I think that the meaning is different. The verb hath chosen, appears to me to be used indefinitely, as the grammarians call it, and in that manner it is often used in other passages of Scripture; for when the Prophets speak of the generality of men:, and relate any common or ordinary occurrence, they do not employ a substantive. I consider the meaning therefore to be, that men cannot frame idols without at the same time framing abomination. This is a remarkable passage for abhorring idols and the presumption of men who make them, which they cannot do without offering the highest insult to God. Some men think that it is amusement, but the Prophet declares it to be “abomination,” which God cannot endure, and will not permit to be unpunished. The word choose points out, as with the finger, the origin of idol-worship; for pure religion would never have been contaminated by so many corruptions, if they had not dared to make gods for themselves according to their own caprice; and therefore it ought to be remarked, that all kinds of worship that are the result of “choice” are at variance with true godliness.
Calvin's commentary on Isaiah 43:11:
11. I, I am Jehovah. Here the Lord employs lofty language, as having obtained the victory. Already he had sufficiently explained in what manner he must be known, and had shewn that there is no God except himself; and now, in order to confirm this doctrine, he exclaims, “I alone am Jehovah, there is none besides me.” This shews how dangerous it is to contrive anything about God out of our own fancy; for when we make any kind of graven image, we produce an idol instead of God. We ought, therefore, to embrace nothing but what has proceeded from God, so as not to allow ourselves any liberty on this subject. After God has revealed himself to us, we ought to make progress in the knowledge of him, and to grow and be strengthened every day; for this is the meaning of the repetition, I, I.

And there is no Savior besides me. That we may not suppose that his eternal essence only is here exhibited, but also his power and goodness, which he constantly exercises towards us, and by which he is fully revealed, he adds an epithet as a distinguishing mark, that “he is the only Savior.” The world falls into the mistake of giving a naked and empty name to God, and at the same time conveying his authority to another, as in Popery God is indeed mentioned, but is robbed of his honor, when one part of it is given to St. Peter, and another to St. Paul, and another to St. William, and another to St. George; that is, his offices are distributed into so many parts, that hardly anything is left to him but a naked and empty name. They boast, indeed, of worshipping God alone; but when we come to what it belongs to God to do, they make as many gods as they have creatures, and distribute among them his power and authority. But the Lord has determined that these shall remain entire and uninfringed, and they cannot be conveyed to another without shocking blasphemy; for he alone does good to men, he alone defends and preserves them. The last clause of the verse expresses that knowledge which is derived from experience, that we may not seek salvation in any other than in him who its the only author of it. Hence we learn that the chief part of the worship of God consists in faith, when he is acknowledged to be the beginning and the end of life, when we bestow on him the title of Savior, and do not convey to another what he declares to belong to himself and to reside in him alone.
Calvin's Commentaries, Vol. 15: Isaiah, Part III, tr. by John King, [1847-50], at sacred-texts.com. From Calvin's commentary on Isaiah 44:10:
10. Who is the maker of God? He pours ridicule on the madness of men who dare to frame gods; for it is a shocking and detestable thing that men should take so much upon them as to create God. Every person certainly will greatly abhor such madness; and yet men are blindly impelled by foolish passion to manufacture gods, and no warning restrains them. On the other hand, they will say that this never entered into any man’s mind, and that injustice is done to them when they are accused of so great madness; just as the Papists in the present day say that we slander them, when we employ these arguments of the Prophet against them. But in vain do they rely on their sophistical reasonings for avoiding this charge. What the Prophet says is most true, that they are so mad as to think that they “make God;” for as soon as the stone or wood has been carved or polished, they ascribe to it divinity, run to it, make prayers, call upon it, and prostrate themselves before it, and in short, ascribe to it those things which they know to belong to God alone.
Which is profitable for nothing. We ought carefully to observe this clause, which condemns as vain and useless all the images by which God is represented. Hence it follows not only that God is insulted, whenever his glory is changed into dead images, but that all who procure idols for themselves lose their pains and suffer damage. Papists allege that they are the books of the unlearned; but this is a paltry evasion, for the Prophet testifies that they are of no use whatever. Let them, therefore, either erase this proof from the Book of Isaiah, or acknowledge that images are vain and useless. Formerly he expressed something more, when he affirmed that nothing can be learned from them but falsehood. But on this subject we have said enough in the exposition of these passages. (Isaiah 40 and 41.)
Calvin on Isaiah 44:15:
In cooking their victuals, and in other conveniences, men perceive that the wood is subject to their control and devoted to their use; how comes it then that they bow down before a piece of wood that has the shape of a man? Is not God in this maimer robbed of his right? And when men call upon images, do they not defraud God of that sacrifice which he chiefly demands? Even heathen writers long ago laughed at this folly, that men ventured to form gods according to their own fancy out of corruptible matter which they formerly despised. Hence came that jest of Horace, “Once I was a trunk of a fig-tree, a useless piece of wood, when a carpenter, uncertain whether to make a bench or a Priapus, preferred that I should be a god; and so I became a god.” But they did not actually know the fountain of impiety, because they did not apply their minds to consider the goodness and power of One God, which is displayed in all the creatures.

When the Prophet thus attacked the worshippers of idols, and laid open their stupidity and madness, they undoubtedly complained that they were unjustly defamed, and endeavored to cloak their errors under plausible pretexts, that they acknowledged that their gods were in heaven, as even their writings shewed, and did not mean that wood or stone is God, in the same manner as the Papists, in arguing against us, defend the same cause with them, and absolutely refuse to be condemned for such gross blindness. But we have already said that the Prophet does not confine his attention to the mere essence of God; and indeed if this be all that is left to God, it will be an idle phantom. He means that all the attributes which belong to him, his foreknowledge, power, government, righteousness, salvation, and everything else, remains unimpaired. Now, when wicked men set up statues or images, and fly to them for the purpose of imploring assistance, and whenever they place them before their eyes and address them, and think that God hears them, do they not wickedly connect their salvation with them? But this stupidity arises from their ignorance of the nature of God, which is simple and spiritual, but which they imagine to be gross and carnal. Thus their thoughts concerning him are excessively wicked, and they east aside and stain his glory, by making it like earthly and fading things. Nothing is so inconsistent with the majesty of God as images; and he who worships them endeavors to shut up God in them, and to treat him according to his own fancy. Justly, therefore, does the Prophet attack such corruptions, and sharply censure the mad zeal of superstitious persons, since nothing more detestable can be uttered or imagined.
Calvin's commentary on Jeremiah 10:8:
Now we may from this passage draw a general truth, - that when men seek to represent God under any visible form, they give way to the delusions and impostures of Satan. Well known is that sentence of Gregory to Serenus, the Bishop of Marseilles, when that good man cast down the images which he saw led to ungodly worship, and purged the churches of Marseilles from such pollutions: Gregory, though a pious man, yet wrote very foolishly - that Serenus acted rightly and wisely in forbidding images to be worshipped, but that he yet acted inconsiderately by emptying the churches of them; for “they are,” he said, “the books of the simple:” this is the conclusion of his epistle. And it is ever in the mouth of Papists - that images are the books of the simple. At the same time I would they retained this truth avowed by Gregory, that they ought not to be worshipped. They worship and adore them, as it is well known, in the place of God. But as I have already said, that answer of Gregory was puerile and foolish: for we hear what the Prophet says, - that in wood and stone and in every outward representation there is vanity, as Habakkuk also in the second chapter, where He speaks of idols, calls an idol the teacher of vanity. Every statue, every image, by which foolish men seek to represent God, is a teacher of falsehood. So our Prophet says, - that the teaching of vanities is found in all statues, because God is thus misrepresented; for what can be in a wood or stone that is like the infinite power of God, or his incomprehensible essence and majesty? Men, therefore, offer a serious affront to God when they thus deform him, as Paul also in Rom_1:25, says, - that the truth was thus changed into falsehood, that is, when he is supposed to have anything like to what external and dead figures have; as the same Paul further reasons in Act_17:29, when he says, Do ye think that God is like to wood or stone, to silver or gold? And his argument was at that time suitable; for he had to do with heafilens: he did not refer to the law, though he might have quoted a passage in Deuteronomy, where God reminded the people that he so appeared to them that they saw no similitude; and he might have referred to the testimonies of Isaiah, Jeremiah, and of the other Prophets; but as he addressed heathens, even the Athenians, he says, “One of your poets has said, that we are the offspring of God:” if we are then, He says, the offspring of God, do ye not draw God down from his celestial throne, when ye seek to delineate him according to your fancies, and suppose that he lies hid in wood or stone, in silver and gold? For some life appears at least in men, they are endued with mind and intelligence, and so far they bear some likeness to God: but a dead wood and stone, which are void of sense, - gold also and silver, which are metals without reason, which have no life, - what affinity, He says, can these have to God? This subject might be more copiously handled; but I merely explain what the Prophet means, and also shew the import of his doctrine, and how it may be applied for general instruction.
Calvin on Jeremiah 51:17:
A log of wood lies on the ground, is trodden under foot without any honor; now when the artificer adds form to it, the log begins to be worshipped as a god; what madness can be imagined greater than this? The same thing may be said of stones, of silver, and of gold; for though it may be a precious metal, yet no divinity is ascribed to it, until it begins to put on a certain form. Now when a melter casts an idol, how can a lump of gold or silver become a god? The Prophet then upbraids this monstrous madness, when he says, that men are in their knowledge like brute beasts, that is, when they apply their skill to things so vain and foolish. But he mentions the same thing twice, according to the common usage of the Hebrew style; for we know that the same thing is often said twice for confirmation by the prophets.
Calvin on Hosea 2:9:
God here shows, that except he denudes idolaters, they will ever continue obstinate. How so? Because they use coverings for their baseness. While the ungodly enjoy their triumphs in the world, they regard them as veils drawn over them, so that nothing base or disgraceful can be seen in them. The same is the case with great kings and monarchs; they think that the eyes of all are dazzled by their splendour; and hence it is, that they are so audaciously dissolute. They think their own filth to be fine odour: such is the arrogance of the world.
Calvin's on Hosea 18:14:
Here the Prophet concludes his foregoing observations. It is indeed probable that he preached them at various times; but, as I have already said, the heads of the sermons which the Prophet delivered are collected in this book, so that we may know what his teaching was. He then discoursed daily on idolatry, on superstitions, and on the other corruptions which then prevailed among the people; he often repeated the same threatenings, but afterwards collected into certain chapters the things which he had spoken. The conclusion, then, of his former teaching was this, that Israel had forgotten his Maker, whilst for himself he had been building temples He says, that he forgot his Maker by building temples because he followed not the directions of the law. We hence see that God will have himself to be known by his word. Israel might have objected and said, that no such thing was intended, when he built temples in Dan and Bethel, but that he wished by these to retain the remembrance of God. But the Prophet here shows that God is not truly known, and that men do not really remember him, except when they worship him according to what the law prescribes, except when they submit themselves wholly to his word, and undertake nothing,and attempt nothing, but what he has commanded. What then the superstitious say is remembrance, the Prophet here plainly testifies is forgetfullness. The case is the same at this day, when we blame the Papists for their idols; their excuse is this, that what they set forth is in pictures and statues the image of God, and that images, as they say, are the books of the illiterate. But what does the Prophet answer here? That Israel forgot his Maker There was an altar in Bethel, and there Israel was wont to offer sacrifices, and they called this the worship of God; but the Prophet shows that each worship was accursed before God, and that it had no other effect than wholly to obliterate the holy name of God from the minds of men, so that the whole of religion perished.

Remarkable then is this passage; for the Prophet says, that the people forgot God their Maker, when they built temples for themselves But what was in the temples so vicious, as to take away the remembrance of God from the world? Even because God would have but one temple and altar. If a reason was asked, a reason might indeed have been given; but the people ought to have acquiesced in the command of God. Though God may not show why he commands this or that, it is enough that we ought to obey his word. Now, then, it appears, that when Israel built for himself various temples, he departed from God, and for this reason, because he followed not the rule of the law, and kept not himself within the limits of the divine command. Hence it was to forget God. We now apprehend the object of the Prophet.

Though then they were wont to glory in their temples, and there to display their pomp and splendor, and proudly to delight in their superstitions, yet the Prophet says, that they had forgotten their Creator, and for this reason only, because they had not continued in his law. He says, that they had forgotten God their Maker; by the word Maker, the Prophet alludes not to God as the framer of the world and the creator of men, but he applies it to the condition of the people. For, as we well know, the favor of God had been peculiar towards that people; he had not only made them, as a part of the human race, but also formed them a people to himself. Since then God had thus intended them to be devoted to him, the Prophet here increases and enhances their sin, when he says, that they obeyed not his word, but followed their own devices and depraved imaginations.
Calvin on John 20:29:
There were many unbelievers who, at that time, beheld Christ with the eyes of flesh, and yet were not more blessed on that account; but we, who have never beheld Christ with the eyes, enjoy that blessedness of which Christ speaks with commendation. Hence it follows, that he calls those eyes blessed which spiritually behold in him what is heavenly and divine; for we now behold Christ in the Gospel in the same manner as if he visibly stood before us. In this sense Paul says to the Galatians, (Gal_3:1,) that Christ was crucified before their eyes; and, therefore, if we desire to see in Christ what may render us happy and blessed, let us learn to believe, when we do not see. To these words of Christ corresponds what is stated in another passage, in which the Apostle commends believers, who

love Christ whom they have not seen, and rejoice with unspeakable joy, though they do not behold him.
(1Pe_1:8.)
Calvin's Commentaries, Vol. 37: Acts, Part II, tr. by John King, [1847-50], at sacred-texts.com. From Calvin's commentary on Acts 17:29:
29. Therefore seeing that. He gathereth that God cannot be figured or resembled by any graven image forasmuch as he would have his image extant in us. For the soul wherein the image of God is properly engraven cannot be painted; therefore it is a thing more absurd to go about to paint God. Now, we see what great injury they do to God which give him a bodily shape; when as man’s soul, which doth scarce resemble a small sparkle of the infinite glory of God, cannot be expressed in any bodily shape.

Furthermore, forasmuch as it is certain that Paul doth in this place inveigh against the common superstition of all the Gentiles, because they would worship God under bodily shapes, we must hold this general doctrine that God is falsely and wickedly transfigured, and that his truth is turned into a lie so often as his Majesty is represented by any visible shape; as the same Paul teacheth in the first chapter to the Romans, (Ro 1:23.) And though the idolaters of all times wanted not their cloaks and colors, yet that was not without cause always objected to them by the prophets which Paul doth now object that God is made like to wood, or stone or gold, when there is any image made to him of dead and corruptible matter. The Gentiles used images that, according to their rudeness, they might better conceive that God was nigh unto them. But seeing that God doth far surpass the capacity of our mind, whosoever attempteth with his mind to comprehend him, he deformeth and disfigureth his glory with a wicked and false imagination. Wherefore, it is wickedness to imagine anything of him according to our own sense. Again, that which worse is, it appeareth plainly that men erect pictures and images to God for no other cause, save only because they conceive some carnal thing of him, wherein he is blasphemed.

The Papists also are at this day no whit more excusable. For what colors soever they invent to paint and color those images, whereby they go about to express God, yet because they be enwrapped in the same error, wherein the men of old time were entangled, they be urged with the of the prophets. And that the heathen did use the same excuses in times past, wherewith the Papists go about to cover themselves at this day, it is well known out of their own books. Therefore, the prophets do not escape the mocks of certain, as if they laid too great grossness to their charge, yea, burthen them with false accusations; but when all things are well weighed, those who will judge rightly shall find, that whatsoever starting holes [evasions] even the most witty men have sought, yet were they taken with this madness, that God is well pleased with the sacrifice done before images. Whereas we, with Erasmus, translate it numen, Luke putteth [θειον] in the neuter gender for divinity or godhead. When Paul denieth that God is like to gold, or silver, or stone, and addeth afterward, graven by cunning or invention of man, he excludeth both matter and form, and doth also condemn all inventions of men, which disfigure the true nature of God.
Calvin's Commentaries, Vol. 38: Romans, tr. by John King, [1847-50], at sacred-texts.com. From Calvin's commentary on Romans 1:23:
The madness then here noticed, is, that all attempted to make for themselves an image of God; which was a certain proof that their notions of God were gross and absurd. And, first, they befouled the majesty of God by forming him in the likeness of a corruptible man: for I prefer this rendering to that of mortal man, which is adopted by Erasmus; for Paul sets not the immortality of God in opposition to the mortality of man, but that glory, which is subject to no defects, to the most wretched condition of man. And then, being not satisfied with so great a crime, they descended even to beasts and to those of the most filthy kind; by which their stupidity appeared still more evident. You may see an account of these abominations in Lactantius, in Eusebius, and in Augustine in his book on the city of God.
Calvin's commentary on 1 Corinthians 8:4:

As to the words, Erasmus reads thus - “An idol has no existence.” I prefer the rendering of the old translation - An idol is nothing. For the argument is this - that an idol is nothing, inasmuch as there is but one God; for it follows admirably - “If there is no other God besides our God, then an idol is an empty dream, and mere vanity.” When he says - and there is none other God but one, I understand the conjunction and as meaning because. For the reason why an idol is nothing is, that it must be estimated according to the thing that it represents. Now it is appointed for the purpose of representing God: nay more, for the purpose of representing false gods, inasmuch as there is but one God, who is invisible and incomprehensible. The reason, too, must be carefully observed - An idol is nothing because there is no God but one; for he is the invisible God, and cannot be represented by a visible sign, so as to be worshipped through means of it. Whether, therefore, idols are erected to represent the true God, or false gods, it is in all cases a perverse contrivance. Hence Habakkuk calls idols teachers of lies, (Hab_2:18,) because they deal falsely in pretending to give a figure or image of God, and deceive men under a false title. Hence οὐδεν (nothing) refers not to essence, but to quality - for an idol is made of some substance - either silver, or wood, or stone; but as God does not choose to be represented in this way, it is vanity and nothing as to meaning and use.

Calvin's commentary on 1 Corinthians 11:24:
Leave to Christ the true nature of flesh, and do not, by a mistaken apprehension, extend his body over heaven and earth: do not divide him into different parts by thy fancies, and do not adore him in this place and that, according to thy carnal apprehension. Allow him to remain in his heavenly glory, and aspire thou thither, that he may thence communicate himself to thee.” These few things will satisfy those that are sound and modest.
Calvin's commentary on 2 Corinthians 5:7:
(Εἰδος) I have here rendered aspectum, (sight,) because few understood the meaning of the word species, (appearance.) He states the reason, why it is that we are now absent from the Lord - because we do not as yet see him face to face. (1Co_13:12.) The manner of that absence is this - that God is not openly beheld by us. The reason why he is not seen by us is, that we walk by faith Now it is on good grounds that faith is opposed to sight, because it, perceives those things that are hid from the view of men - because it reaches forth to future things, which do not as yet appear. For such is the condition of believers, that they resemble the dead rather than the living - that they often seem as if they were forsaken by God - that they always have the elements of death shut up within them. Hence they must necessarily hope against hope. (Rom_4:18.) Now the things that are hoped for are hid, as we read in Rom_8:24, and faith is the

manifestation of things which do not appear.
(Heb_11:1.)

It is not to be wondered, then, if the apostle says, that we have not as yet the privilege of sight, so long as we walk by faith. For we see, indeed, but it is through a glass, darkly; (1Co_13:12,) that is, in place of the reality we rest upon the word.
Calvin's commentary on Galatians 1:6:
6. I wonder. He commences by administering a rebuke, though a somewhat milder one than they deserved; but his greatest severity of language is directed, as we shall see, against the false apostles. He charges them with turning aside, not only from his gospel, but from Christ; for it was impossible for them to retain their attachment to Christ, without acknowledging that he has graciously delivered us from the bondage of the law. But such a belief cannot be reconciled with those notions respecting the obligation of ceremonial observance which the false apostles inculcated. They were removed from Christ; not that they entirely rejected Christianity, but that the corruption of their doctrines was such as to leave them nothing more than an imaginary Christ.
Thus, in our own times, the Papists, choosing to have a divided and mangled Christ, have none, and are therefore “removed from Christ.” They are full of superstitions, which are directly at variance with the nature of Christ.
Let it be carefully observed, that we are removed from Christ, when we fall into those views which are inconsistent with his mediatorial office; for light can have no fellowship with darkness.
On the same principle, he calls it another gospel, that is, a gospel different from the true one. And yet the false apostles professed that they preached the gospel of Christ; but, mingling with it their own inventions, by which its principal efficacy was destroyed, they held a false, corrupt, and spurious gospel. By using the present tense, (“ye are removed”) he appears to say that they were only in the act of failing. As if he had said, “I do not yet say that ye have been removed; for then it would be more difficult to return to the right path. But now, at the critical moment, do not advance a single step, but instantly retreat.”
From Christ, who called you by grace. Others read it, “from him who called you by the grace of Christ,” understanding it to refer to the Father; but the reading which we have followed is more simple. When he says that they were called by Christ through grace, this tends to heighten the criminality of their ingratitude. To revolt from the Son of God under any circumstances, is unworthy and disgraceful; but to revolt from him, after being invited to partake salvation by grace, is more eminently base. His goodness to us renders our ingratitude to him more dreadfully heinous.
So soon. When it is considered how soon they had discovered a want of steadfastness, their guilt is still further heightened. A proper season, indeed, for departing from Christ cannot be imagined. But the fact, that no sooner had Paul left them than the Galatians were led away from the truth, inferred still deeper blame. As the consideration of the grace by which they had been called was adduced to aggravate their ingratitude, so the circumstance of the time when they were removed is now adduced to aggravate their levity.
Calvin on Galatians 4:1:
In aiding the ignorant, we must employ not those methods which the fancy of men may have been pleased to contrive, but those which had been fixed by God himself, who unquestionably has left out nothing that was fitted to assist their weakness. Let this shield suffice for repelling any objections: “God has judged otherwise, and his purpose supplies to us the place of all arguments; unless it be supposed that men are capable of devising better aids than those which God had provided, and which he afterwards threw aside as useless.”
Calvin on Colossians 1:15:
God in himself, that is, in his naked majesty, is invisible, and that not to the eyes of the body merely, but also to the understandings of men, and that he is revealed to us in Christ alone, that we may behold him as in a mirror. For in Christ he shews us his righteousness, goodness, wisdom, power, in short, his entire self. We must, therefore, beware of seeking him elsewhere, for everything that would set itself off as a representation of God, apart from Christ, will be an idol.
Calvin on Hebrews 6:19:

19.As an anchor, etc. It is a striking likeness when he compares faith leaning on God’s word to an anchor; for doubtless, as long as we sojourn in this world, we stand not on firm ground, but are tossed here and there as it were in the midst of the sea, and that indeed very turbulent; for Satan is incessantly stirring up innumerable storms, which would immediately upset and sink our vessel, were we not to cast our anchor fast in the deep. For nowhere a haven appears to our eyes, but wherever we look water alone is in view; yea, waves also arise and threaten us; but as the anchor is cast through the waters into a dark and unseen place, and while it lies hid there, keeps the vessel beaten by the waves from being overwhelmed; so must our hope be fixed on the invisible God. There is this difference, - the anchor is cast downwards into the sea, for it has the earth as its bottom; but our hope rises upwards and soars aloft, for in the world it finds nothing on which it can stand, nor ought it to cleave to created things, but to rest on God alone. As the cable also by which the anchor is suspended joins the vessel with the earth through a long and dark intermediate space, so the truth of God is a bond to connect us with himself, so that no distance of place and no darkness can prevent us from cleaving to him. Thus when united to God, though we must struggle with continual storms, we are yet beyond the peril of shipwreck. Hence he says, that this anchor is sure and steadfast, or safe and firm. It may indeed be that by the violence of the waves the anchor may be plucked off, or the cable be broken, or the beaten ship be torn to pieces. This happens on the sea; but the power of God to sustain us is wholly different, and so also is the strength of hope and the firmness of his word.

Which entereth into that, or those things, etc. As we have said, until faith reaches to God, it finds nothing but what is unstable and evanescent; it is hence necessary for it to penetrate even into heaven. But as the Apostle is speaking to the Jews, he alludes to the ancient Tabernacle, and says, that they ought not to abide in those things which are seen, but to penetrate into the inmost recesses, which lie hid within the veil, as though he had said, that all the external and ancient figures and shadows were to be passed over, in order that faith might be fixed on Christ alone.

And carefully ought this reasoning to be observed, - that as Christ has entered into heaven, so faith ought to be directed there also: for we are hence taught that faith should look nowhere else. And doubtless it is in vain for man to seek God in his own majesty, for it is too far removed from them; but Christ stretches forth his hand to us, that he may lead us to heaven. And this was shadowed forth formerly under the Law; for the high priest entered the holy of holies, not in his own name only, but also in that of the people, inasmuch as he bare in a manner the twelve tribes on his breast and on his shoulders; for as a memorial for them twelve stones were wrought on the breastplate, and on the two onyx stones on his shoulders were engraved their names, so that in the person of one man all entered into the sanctuary together. Rightly then does the Apostle speak, when he reminds them that our high priest has entered into heaven; for he has not entered only for himself, but also for us. There is therefore no reason to fear that access to heaven will be closed up against our faith, as it is never disjoined from Christ. And as it becomes us to follow Christ who is gone before, he is therefore called our Forerunner, or precursor.

Calvin's commentary on Hebrews 11:6:
It does not indeed seem a great matter, when the Apostle requires us to believe that God is; but when you more closely consider it, you will find that there is here a rich, profound, and sublime truth; for though almost all admit without disputing that God is, yet it is evident, that except the Lord retains us in the true and certain knowledge of himself, various doubts will ever creep in, and obliterate every thought of a Divine Being. To this vanity the disposition of man is no doubt prone, so that to forget God becomes an easy thing. At the same time the Apostle does not mean, that men ought to feel assured that there is some God, for he speaks only of the true God; nay, it will not be sufficient for you to form a notion of any God you please; but you must understand what sort of Being the true God is; for what will it profit us to devise and form an idol, and to ascribe to it the glory due to God?

We now then perceive what the Apostle means in the first clause; he denies that we can have an access to God, except we have the truth, that God is deeply fixed in our hearts, so as not to be led here and there by various opinions.

It is hence evident, that men in vain weary themselves in serving God, except they observe the right way, and that all religions are not only vain, but also pernicious, with which the true and certain knowledge of God is not connected; for all are prohibited from having any access to God, who do not distinguish and separate him from all idols; in short, there is no religion except where this truth reigns dominant. But if the true knowledge of God has its seat in our hearts it will not fail to lead us to honor and fear him; for God, without his majesty is not really known. Hence arises the desire to serve him, hence it comes that the whole life is so formed, that he is regarded as the end in all things.
Calvin's Commentaries, Vol. 45: Catholic Epistles, tr. by John King, [1847-50], at sacred-texts.com. Calvin's commentary on 1 Peter 1:8:
At the appearing of Jesus Christ, or, when Jesus Christ shall be revealed. This is added, that the faithful might learn to hold on courageously to the last day. For our life is now hidden in Christ, and will remain hidden, and as it were buried, until Christ shall appear from heaven; and the whole course of our life leads to the destruction of the external man, and all the things we suffer are, as it were, the preludes of death. It is hence necessary, that we should cast our own eyes on Christ, if we wish in our afflictions to behold glory and praise. For trials as to us are full of reproach and shame, and they become glorious in Christ; but that glory in Christ is not yet plainly seen, for the day of consolation is not yet come. 12

8 Whom having not seen, or, Whom though ye have not seen. He lays down two things, that they loved Christ whom they had not seen, and that they believed on him whom they did not then behold. But the first arises from the second; for the cause of love is faith, not only because the knowledge of those blessings which Christ bestows on us, moves us to love him, but because he offers us perfect felicity, and thus draws us up to himself. He then commends the Jews, because they believed in Christ whom they did not see, that they might know that the nature of faith is to acquiesce in those blessings which are hid from our eyes. They had indeed given some proof of this very thing, though he rather directs what was to be done by praising them.

The first clause in order is, that faith is not to be measured by sight. For when the life of Christians is apparently miserable, they would instantly fail, were not their happiness dependent on hope. Faith, indeed, has also its eyes, but they are such as penetrate into the invisible kingdom of God, and are contented with the mirror of the Word; for it is the demonstration of invisible things, as it is said in Heb 11:1. Hence true is that saying of Paul, that

we are absent from the Lord while we are in the flesh;
for we walk by faith and not by sight.
(2Co 5:6-7.)

The second clause is, that faith is not a cold notion, but that it kindles in our hearts love to Christ. For faith does not (as the sophists prattle) lay hold on God in a confused and implicit manner, (for this would be to wander through devious paths;) but it has Christ as its object. Moreover, it does not lay hold on the bare name of Christ, or his naked essence, but regards what he is to us, and what blessings he brings; for it cannot be but that the affections of man should be led there, where his happiness is, according to that saying,

“Where your treasure is, there is also your heart.” (Mt 6:21.)

Ye rejoice, or, Ye exult. He again refers to the fruit of faith which he had mentioned, and not without reason; for it is an incomparable benefit, that consciences are not only at peace before God, but confidently exult in the hope of eternal life. And he calls it joy unspeakable, or unutterable, because the peace of God exceeds all comprehension. What is added, full of glory, or glorified, admits of two explanations. It means either what is magnificent and glorious, or what is contrary to that which is empty and fading, of which men will soon be ashamed. Thus “glorified” is the same with what is solid and permanent, beyond the danger of being brought to nothing. 13 Those who are not elevated by this joy above the heavens, so that being content with Christ alone, they despise the world, in vain boast that they have faith.

Calvin on 1 John 2:22:
22Who is a liar He does not assert that they alone were liars who denied that the Son of God appeared in the flesh, lest no one in unloosing the knot should above measure torment himself; but that they surpassed all others, as though he had said, that except this be deemed a lie, no other could be so reckoned; as we are wont commonly to say, “If perfidy towards God and men is not a crime, what else can we call a crime?”
What he had generally said of false prophets, he now applies to the state of his own time; for he points out, as by the finger, those who disturbed the Church. I readily agree with the ancients, who thought that Cerinthus and Carpocrates are here referred to. But the denial of Christ extends much wider; for it is not enough in words to confess that Jesus is the Christ, except he is acknowledged to be such as the Father offers him to us in the gospel. The two I have named gave the title of Christ to the Son of God, but imagined him to be man only. Others followed them, such as Arius, who, adorning him with the name of God, robbed him of his eternal divinity. Marcion dreamt that he was a mere phantom. Sabellius imagined that he differed nothing from the Father. All these denied the Son of God; for not one of them really acknowledged the true Christ; but, adulterating, as far as they could, the truth respecting him, they devised for themselves an idol instead of Christ. Then broke out Pelagius, who, indeed, raised no dispute respecting Christ’s essence, but allowed him to be true man and God; yet he transferred to us almost all the honor that belongs to him. It is, indeed, to reduce Christ to nothing, when his grace and power are set aside.
So the Papists, at this day, setting up freewill in opposition to the grace of the Holy Spirit, ascribing a part of their righteousness and salvation to the merits of works, feigning for themselves innumerable advocates, by whom they render God propitious to them, have a sort of fictitious Christ, I know not what; but the lively and genuine image of God, which shines forth in Christ, they deform by their wicked inventions; they lessen his power, subvert and pervert his office.
We now see that Christ, is denied, whenever those things which peculiarly belong to him, are taken away from him. And as Christ is the end of the law and of the gospel, and has in himself all the treasures of wisdom and knowledge, so he is the mark at which all heretics level and direct their arrows. Therefore the Apostle does not, without reason, make those the chief impostors, who fight against Christ, in whom the full truth is exhibited to us.
He is Antichrist He speaks not of that prince of defection who was to occupy the seat of God; but all those who seek to overthrow Christ, he puts them among that impious band. And that he might amplify their crime, he asserts that the Father, no less than the Son, is denied by them; as though he had said, “They have no longer any religion, because they wholly cast away God.” And this he afterwards confirms, by adding this reason, that the Father cannot be separated from the Son.
Calvin's Commentaries, Vol. 45: Catholic Epistles, tr. by John King, [1847-50], at sacred-texts.com. Calvin's commentary on 1 John 5:21:
21 Keep yourselves from idols Though this be a separate sentence, yet it is as it were an appendix to the preceding doctrine. For the vivifying light of the Gospel ought to scatter and dissipate, not only darkness, but also all mists, from the minds of the godly. The Apostle not only condemns idolatry, but commands us to beware of all images and idols; by which he intimates, that the worship of God cannot continue uncorrupted and pure whenever men begin to be in love with idols or images. For so innate in us is superstition, that the least occasion will infect us with its contagion. Dry wood will not so easily burn when coals are put under it, as idolatry will lay hold on and engross the minds of men, when an occasion is given to them. And who does not see that images are the sparks? What sparks do I say? nay, rather torches, which are sufficient to set the whole world on fire.

The Apostle at the same time does not only speak of statues, but also of altars, and includes all the instruments of superstitions. Moreover, the Papists are ridiculous, who pervert this passage and apply it to the statues of Jupiter and Mercury and the like, as though the Apostle did not teach generally, that there is a corruption of religion whenever a corporeal form is ascribed to God, or whenever statues and pictures form a part of his worship. Let us then remember that we ought carefully to continue in the spiritual worship of God, so as to banish far from us everything that may turn us aside to gross and carnal superstitions.
