Part 1
What defence, then, what proof that these are real gods, can they offer who hold this superstition? For, by what has been said just above, our argument has demonstrated them to be men, and not respectable men. But perhaps they will turn to another argument, and proudly appeal to the things useful to life discovered by them, saying that the reason why they regard them as gods is their having been of use to mankind. For Zeus is said to have possessed the plastic art, Poseidon that of the pilot, Hephæstus the smith's, Athena that of weaving, Apollo that of music, Artemis that of hunting, Hera dressmaking, Demeter agriculture, and others other arts, as those who inform us about them have related. 2. But men ought to ascribe them and such like arts not to the gods alone but to the common nature of mankind, for by observing nature men discover the arts. For even common parlance calls art an imitation of nature. If then they have been skilled in the arts they pursued, that is no reason for thinking them gods, but rather for thinking them men; for the arts were not their creation, but in them they, like others, imitated nature. 3. For men having a natural capacity for knowledge according to the definition laid down concerning them, there is nothing to surprise us if by human intelligence, and by looking of themselves at their own nature and coming to know it, they have hit upon the arts. Or if they say that the discovery of the arts entitles them to be proclaimed as gods, it is high time to proclaim as gods the discoverers of the other arts on the same grounds as the former were thought worthy of such a title. For the Phœnicians invented letters, Homer epic poetry, Zeno of Elea dialectic, Corax of Syracuse rhetoric, Aristæus bee-keeping, Triptolemus the sowing of grain, Lycurgus of Sparta and Solon of Athens laws; while Palamedes discovered the arrangement of letters, and numbers, and measures and weights. And others imparted various other things useful for the life of mankind, according to the testimony of our historians. 4. If then the arts make gods, and because of them carved gods exist, it follows, on their showing, that those who at a later date discovered the other arts must be gods. Or if they do not deem these worthy of divine honour, but recognise that they are men, it were but consistent not to give even the name of gods to Zeus, Hera, and the others, but to believe that they too have been human beings, and all the more so, inasmuch as they were not even respectable in their day; just as by the very fact of sculpturing their form in statues they show that they are nothing else but men.
19. The inconsistency of image worship. Arguments in palliation. (1) The divine nature must be expressed in a visible sign. (2) The image a means of supernatural communications to men through angels.
For what other form do they give them by sculpture but that of men and women and of creatures lower yet and of irrational nature, all manner of birds, beasts both tame and wild, and creeping things, whatsoever land and sea and the whole realm of the waters produce? For men having fallen into the unreasonableness of their passions and pleasures, and unable to see anything beyond pleasures and lusts of the flesh, inasmuch as they keep their mind in the midst of these irrational things, they imagined the divine principle to be in irrational things, and carved a number of gods to match the variety of their passions. 2. For there are with them images of beasts and creeping things and birds, as the interpreter of the divine and true religion says, “They became vain in their reasonings, and their senseless heart was darkened. Professing themselves to be wise, they became fools, and changed the glory of the incorruptible God for the likeness of an image of corruptible man, and of birds and four-footed beasts and creeping things, wherefore God gave them up unto vile passions.” For having previously infected their soul, as I said above, with the irrationalities of pleasures, they then came down to this making of gods; and, once fallen, thenceforward as though abandoned in their rejection of God, thus they wallow in them, and portray God, the Father of the Word, in irrational shapes. 3. As to which those who pass for philosophers and men of knowledge among the Greeks, while driven to admit that their visible gods are the forms and figures of men and of irrational objects, say in defence that they have such things to the end that by their means the deity may answer them and be made manifest; because otherwise they could not know the invisible God, save by such statues and rites. 4. While those who profess to give still deeper and more philosophical reasons than these say, that the reason of idols being prepared and fashioned is for the invocation and manifestation of divine angels and powers, that appearing by these means they may teach men concerning the knowledge of God; and that they serve as letters for men, by referring to which they may learn to apprehend God, from the manifestation of the divine angels effected by their means. Such then is their mythology,— for far be it from us to call it a theology. But if one examine the argument with care, he will find that the opinion of these persons also, not less than that of those previously spoken of, is false.
20. But where does this supposed virtue of the image reside? In the material, or in the form, or in the maker's skill? Untenability of all these views.
For one might reply to them, bringing the case before the tribunal of truth, How does God make answer or become known by such objects? Is it due to the matter of which they consist, or to the form which they possess? For if it be due to the matter, what need is there of the form, instead of God manifesting Himself through all matter without exception before these things were fashioned? And in vain have they built their temples to shut in a single stone, or stock, or piece of gold, when all the world is full of these substances. 2. But if the superadded form be the cause of the divine manifestation, what is the need of the material, gold and the rest, instead of God manifesting Himself by the actual natural animals of which the images are the figures? For the opinion held about God would on the same principle have been a nobler one, were He to manifest Himself by means of living animals, whether rational or irrational, instead of being looked for in things without life or motion. 3. Wherein they commit the most signal impiety against themselves. For while they abominate and turn from the real animals, beasts, birds, and creeping things, either because of their ferocity or because of their dirtiness, yet they carve their forms in stone, wood, or gold, and make them gods. But it would be better for them to worship the living things themselves, rather than to worship their figures in stone. 4. But perhaps neither is the case, nor is either the material or the form the cause of the divine presence, but it is only skilful art that summons the deity, inasmuch as it is an imitation of nature. But if the deity communicates with the inmates on account of the art, what need, once more, of the material, since the art resides in the men? For if God manifests Himself solely because of the art, and if for this reason the images are worshipped as gods, it would be right to worship and serve the men who are masters of the art, inasmuch as they are rational also, and have the skill in themselves.
21. The idea of communications through angels involves yet wilder inconsistency, nor does it, even if true, justify the worship of the image.
