This is one of those long chapters that the editors nusally divide into three. The issue is images: ikons, and by extension the destruction of ikons. No one would argue that we should worship such: the reformed argue that we should not keep them or value them. The Catholic and Orthodox have a tradition of religious art, and over time many Protestants began to appreciate this art -- which, like much church music, is of great beauty and part of our Western culture.
A man educated with the full intensity of the French Renaissance disagrees. Admittedly, the authorits in Paris drove him and any other reformed believers out.
1. AS Scripture, in accommodation to the rude and gross intellect of man, usually speaks in popular terms, so whenever its object is to discriminate between the true God and false deities, it opposes him in particular to idols; not that it approves of what is taught more elegantly and subtilely by philosophers, but that it may the better expose the folly, nay, madness of the world in its inquiries after God, so long as every one clings to his own speculations. This exclusive definition, which we uniformly meet with in Scripture, annihilates every deity which men frame for themselves of their own accord--God himself being the only fit witness to himself. Meanwhile, seeing that this brutish stupidity has overspread the globe, men longing after visible forms of God, and so forming deities of wood and stone, silver and gold, or of any other dead and corruptible matter, we must hold it as a first principle, that as often as any form is assigned to God, his glory is corrupted by an impious lie. In the Law, accordingly, after God had claimed the glory of divinity for himself alone, when he comes to show what kind of worship he approves and rejects, he immediately adds, "Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or in the earth beneath, or in the water under the earth," (Exod. 20:4). By these words he curbs any licentious attempt we might make to represent him by a visible shape, and briefly enumerates all the forms by which superstition had begun, even long before, to turn his truth into a lie. For we know that the Sun was worshipped by the Persian. As many stars as the foolish nations saw in the sky, so many gods they imagined them to be. Then to the Egyptians, every animal was a figure of God. The Greeks, again, plumed themselves on their superior wisdom in worshipping God under the human form (Maximum Tyrius Platonic. Serm. 38). But God makes no comparison between images, as if one were more, and another less befitting; he rejects, without exception, all shapes and pictures, and other symbols by which the superstitious imagine they can bring him near to them.
2. This may easily be inferred from the reasons which he annexes to his prohibition. First, it is said in the books of Moses (Deut. 4:15), "Take ye therefore good heed unto yourselves; for ye saw no manner of similitude in the day that the Lord spake unto you in Horeb, out of the midst of the fire, lest ye corrupt yourselves, and make you a graven image, the similitude of any figure," &c. We see how plainly God declares against all figures, to make us aware that all longing after such visible shapes is rebellion against him. Of the prophets, it will be sufficient to mention Isaiah, who is the most copious on this subjects (Isaiah 40:18; 41:7, 29; 45:9; 46:5), in order to show how the majesty of God is defiled by an absurd and indecorous fiction, when he who is incorporeal is assimilated to corporeal matter; he who is invisible to a visible image; he who is a spirit to an inanimate object; and he who fills all space to a bit of paltry wood, or stone, or gold. Paul, too, reasons in the same way, "Forasmuch, then, as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device," (Acts 17:29). Hence it is manifest, that whatever statues are set up or pictures painted to represent God, are utterly displeasing to him, as a kind of insults to his majesty. And is it strange that the Holy Spirit thunders such responses from heaven, when he compels even blind and miserable idolaters to make a similar confession on the earth? Seneca's complaint, as given by Augustine De Civit. Dei, c. 10, is well known. He says "The sacred immortal, and invisible gods they exhibit in the meanest and most ignoble materials, and dress them in the clothing of men and beasts; some confound the sexes, and form a compound out of different bodies, giving the name of deities to objects, which, if they were met alive, would be deemed monsters." Hence, again, it is obvious, that the defenders of images resort to a paltry quibbling evasion, when they pretend that the Jews were forbidden to use them on account of their proneness to superstition; as if a prohibition which the Lord founds on his own eternal essences and the uniform course of nature, could be restricted to a single nation. Besides, when Paul refuted the error of giving a bodily shape to God, he was addressing not Jews, but Athenians.
3. It is true that the Lord occasionally manifested his presence by certain signs, so that he was said to be seen face to face; but all the signs he ever employed were in apt accordance with the scheme of doctrine, and, at the same time, gave plain intimation of his incomprehensible essence. For the cloud, and smoke, and flame, though they were symbols of heavenly glory (Deut. 4:11), curbed men's minds as with a bridle, that they might not attempt to penetrate farther. Therefore, even Moses (to whom, of all men, God manifested himself most familiarly) was not permitted though he prayed for it, to behold that face, but received for answer, that the refulgence was too great for man (Exod. 33:20). The Holy Spirit appeared under the form of a dove, but as it instantly vanished, who does not see that in this symbol of a moment, the faithful were admonished to regard the Spirit as invisible, to be contented with his power and grace, and not call for any external figure? God sometimes appeared in the form of a man, but this was in anticipation of the future revelation in Christ, and, therefore, did not give the Jews the least pretext for setting up a symbol of Deity under the human form. The mercy-seat, also (Exod. 25:17, 18, 21), where, under the Law, God exhibited the presence of his power, was so framed, as to intimate that God is best seen when the mind rises in admiration above itself: the Cherubim with outstretched wings shaded, and the veil covered it, while the remoteness of the place was in itself a sufficient concealment. It is therefore mere infatuation to attempt to defend images of God and the saints by the example of the Cherubim. For what, pray, did these figures mean, if not that images are unfit to represent the mysteries of God, since they were so formed as to cover the mercy-seat with their wings, thereby concealing the view of God, not only from the eye, but from every human sense, and curbing presumption? To this we may add, that the prophets depict the Seraphim, who are exhibited to us in vision, as having their faces veiled; thus intimating, that the refulgence of the divine glory is so great, that even the angels cannot gaze upon it directly, while the minute beams which sparkle in the face of angels are shrouded from our view. Moreover, all men of sound Judgment acknowledge that the Cherubim in question belonged to the old tutelage of the law. It is absurd, therefore, to bring them forward as an example for our age. For that period of puerility, if I may so express it, to which such rudiments were adapted, has passed away. And surely it is disgraceful, that heathen writers should be more skilful interpreters of Scripture than the Papists. Juvenal (Sat. 14) holds up the Jews to derision for worshipping the thin clouds and firmament. This he does perversely and impiously; still, in denying that any visible shape of Deity existed among them, he speaks more accurately than the Papists, who prate about there having been some visible image. In the fact that the people every now and then rushed forth with boiling haste in pursuit of idols, just like water gushing forth with violence from a copious spring, let us learn how prone our nature is to idolatry, that we may not, by throwing the whole blame of a common vice upon the Jews, be led away by vain and sinful enticements to sleep the sleep of death.
4. To the same effect are the words of the Psalmist (Psalms 115:4, 135:15), "Their idols are silver and gold, the works of men's hands." From the materials of which they are made, he infers that they are not gods, taking it for granted that every human device concerning God is a dull fiction. He mentions silver and gold rather than clay or stone, that neither splendour nor cost may procure reverence to idols. He then draws a general conclusion, that nothing is more unlikely than that gods should be formed of any kind of inanimate matter. Man is forced to confess that he is but the creature of a day (see Book 3 c. 9 s. 2), and yet would have the metal which he has deified to be regarded as God. Whence had idols their origin, but from the will of man? There was ground, therefore, for the sarcasm of the heathen poet (Hor. Sat. I. 8), "I was once the trunk of a fig-tree, a useless log, when the tradesman, uncertain whether he should make me a stool, &c., chose rather that I should be a god." In other words, an earth-born creature, who breathes out his life almost every moment, is able by his own device to confer the name and honour of deity on a lifeless trunk. But as that Epicurean poet, in indulging his wit, had no regard for religion, without attending to his jeers or those of his fellows, let the rebuke of the prophet sting, nay, cut us to the heart, when he speaks of the extreme infatuation of those who take a piece of wood to kindle a fire to warm themselves, bake bread, roast or boil flesh, and out of the residue make a god, before which they prostrate themselves as suppliants (Isaiah 44:16). Hence, the same prophet, in another place, not only charges idolaters as guilty in the eye of the law, but upbraids them for not learning from the foundations of the earth, nothing being more incongruous than to reduce the immense and incomprehensible Deity to the stature of a few feet. And yet experience shows that this monstrous proceeding, though palpably repugnant to the order of nature, is natural to man. It is, moreover, to be observed, that by the mode of expression which is employed, every form of superstition is denounced. Being works of men, they have no authority from God (Isa. 2:8, 31:7; Hos. 14:3; Mic. 5:13); and, therefore, it must be regarded as a fixed principle, that all modes of worship devised by man are detestable. The infatuation is placed in a still stronger light by the Psalmist (Psalm 115:8), when he shows how aid is implored from dead and senseless objects, by beings who have been endued with intelligence for the very purpose of enabling them to know that the whole universe is governed by Divine energy alone. But as the corruption of nature hurries away all mankind collectively and individually into this madness, the Spirit at length thunders forth a dreadful imprecation, "They that make them are like unto them, so is every one that trusteth in them." And it is to be observed, that the thing forbidden is likeness, whether sculptured or otherwise. This disposes of the frivolous precaution taken by the Greek Church. They think they do admirably, because they have no sculptured shape of Deity, while none go greater lengths in the licentious use of pictures. The Lord, however, not only forbids any image of himself to be erected by a statuary, but to be formed by any artist whatever, because every such image is sinful and insulting to his majesty.
5. I am not ignorant, indeed, of the assertion, which is now more than threadbare, "that images are the books of the unlearned." So said Gregory: a but the Holy Spirit goes a very different decision; and had Gregory got his lesson in this matter in the Spirit's school, he never would have spoken as he did. For when Jeremiah declares that "the stock is a doctrine of vanities," (Jer. 10:8), and Habakkuk, "that the molten image" is "a teacher of lies," the general doctrine to be inferred certainly is, that every thing respecting God which is learned from images is futile and false. If it is objected that the censure of the prophets is directed against those who perverted images to purposes of impious superstition, I admit it to be so; but I add (what must be obvious to all), that the prophets utterly condemn what the Papists hold to be an undoubted axiom--viz. that images are substitutes for books. For they contrast images with the true God, as if the two were of an opposite nature, and never could be made to agree. In the passages which I lately quoted, the conclusion drawn is, that seeing there is one true God whom the Jews worshipped, visible shapes made for the purpose of representing him are false and wicked fictions; and all, therefore, who have recourse to them for knowledge are miserably deceived. In short, were it not true that all such knowledge is fallacious and spurious, the prophets would not condemn it in such general terms. This at least I maintain, that when we teach that all human attempts to give a visible shape to God are vanity and lies, we do nothing more than state verbatim what the prophets taught.
6. Moreover, let Lactantius and Eusebius be read on this subject. These writers assume it as an indisputable fact, that all the beings whose images were erected were originally men. In like manner, Augustine distinctly declares, that it is unlawful not only to worship images, but to dedicate them. And in this he says no more than had been long before decreed by the Libertine Council, the thirty-sixth Canon of which is, "There must be no pictures used in churches: Let nothing which is adored or worshipped be painted on walls." But the most memorable passage of all is that which Augustine quotes in another place from Varro, and in which he expressly concurs:--"Those who first introduced images of the gods both took away fear and brought in error." Were this merely the saying of Varro, it might perhaps be of little weight, though it might well make us ashamed, that a heathen, groping as it were in darkness, should have attained to such a degree of light, as to see that corporeal images are unworthy of the majesty of God, and that, because they diminish reverential fear and encourage error. The sentiment itself bears witness that it was uttered with no less truth than shrewdness. But Augustine, while he borrows it from Varro, adduces it as conveying his own opinion. At the outset, indeed, he declares that the first errors into which men fell concerning God did not originate with images, but increased with them, as if new fuel had been added. Afterwards, he explains how the fear of God was thereby extinguished or impaired, his presence being brought into contempt by foolish, and childish, and absurd representations. The truth of this latter remark I wish we did not so thoroughly experience. Whosoever, therefore, is desirous of being instructed in the true knowledge of God must apply to some other teacher than images.
7. Let Papists, then, if they have any sense of shame, henceforth desist from the futile plea, that images are the books of the unlearned--a plea so plainly refuted by innumerable passages of Scripture. And yet were I to admit the plea, it would not be a valid defence of their peculiar idols. It is well known what kind of monsters they obtrude upon us as divine. For what are the pictures or statues to which they append the names of saints, but exhibitions of the most shameless luxury or obscenity? Were any one to dress himself after their model, he would deserve the pillory. Indeed, brothels exhibit their inmates more chastely and modestly dressed than churches do images intended to represent virgins. The dress of the martyrs is in no respect more becoming. Let Papists then have some little regard to decency in decking their idols, if they would give the least plausibility to the false allegation, that they are books of some kind of sanctity. But even then we shall answer, that this is not the method in which the Christian people should be taught in sacred places. Very different from these follies is the doctrine in which God would have them to be there instructed. His injunction is, that the doctrine common to all should there be set forth by the preaching of the Word, and the administration of the sacraments,--a doctrine to which little heed can be given by those whose eyes are carried too and fro gazing at idols. And who are the unlearned, whose rudeness admits of being taught by images only? Just those whom the Lord acknowledges for his disciples; those whom he honours with a revelation of his celestial philosophy, and desires to be trained in the saving mysteries of his kingdom. I confess, indeed, as matters now are, there are not a few in the present day who cannot want such books. But, I ask, whence this stupidity, but just because they are defrauded of the only doctrine which was fit to instruct them? The simple reason why those who had the charge of churches resigned the office of teaching to idols was, because they themselves were dumb. Paul declares, that by the true preaching of the gospel Christ is portrayed and in a manner crucified before our eyes (Gal. 3:1). Of what use, then, were the erection in churches of so many crosses of wood and stone, silver and gold, if this doctrine were faithfully and honestly preached--viz. Christ died that he might bear our curse upon the tree, that he might expiate our sins by the sacrifice of his body, wash them in his blood, and, in short, reconcile us to God the Father? From this one doctrine the people would learn more than from a thousand crosses of wood and stone. As for crosses of gold and silver, it may be true that the avaricious give their eyes and minds to them more eagerly than to any heavenly instructor.
