Justin Martyr, First Apology 9

We do not honor the images that human beings have carved and set up in temples with crowds of sacrifices and garlands of flowers. We know that such objects are lifeless and dead, and that they lack the form of God. We do not believe that God possesses the kind of form that some claim these statues imitate in his honor; on the contrary, these images bear the names and shapes of the evil demons that have appeared. Why should I describe for you what you already know: the way craftsmen work the material, melting, cutting, casting, and hammering it? They often take worthless substances and, by changing nothing but the outward shape through their art, call the results gods. We regard this not only as irrational but as an insult to God, who possesses unspeakable glory and form, yet is named over perishable things that need constant care. You know perfectly well that the artisans who make these idols are licentious and steeped in every kind of wickedness, so much so that I need not list it all; they even corrupt the servant girls who work beside them. Oh, the shamelessness of it: lawless men are said to fashion and transform objects into gods to be worshiped, and then appoint such men as guardians of the sacred places where the idols stand, never perceiving that it is unlawful even to think or say that human beings could be guardians of gods.
