On the Roman Catholic Church and its defense of idols (or icons if you prefer that term):

John, deputy of the Eastern Churches, said, “God created man in his own image,” and thence inferred that images ought to be used. He also thought there was a recommendation of images in the following passage, “Show me thy face, for it is beautiful.” Another, in order to prove that images ought to be placed on altars, quoted the passage, “No man, when he has lighted a candle, putteth it under a bushel.” Another, to show the utility of looking at images, quoted a verse of the Psalms “The light of thy countenance, O Lord, has shone upon us.” Another laid hold of this similitude: As the Patriarchs used the sacrifices of the Gentiles, so ought Christians to use the images of saints instead of the idols of the Gentiles. They also twisted to the same effect the words, “Lord, I have loved the beauty of thy house.” But the most ingenious interpretation was the following, “As we have heard, so also have we seen;” therefore, God is known not merely by the hearing of the word, but also by the seeing of images. Bishop Theodore was equally acute: “God,” says he, “is to be admired in his saints;” and it is elsewhere said, “To the saints who are on earth;” therefore this must refer to images. In short, their absurdities are so extreme that it is painful even to quote them.

Were one, with the view of turning the defenders of images into ridicule, to put words into their mouths, could they be made to utter greater and grosser absurdities? But to put an end to all doubt on the subject of images, Theodosius Bishop of Mira confirms the propriety of worshipping them by the dreams of his archdeacon, which he adduces with as much gravity as if he were in possession of a response from heaven. Let the patrons of images now go and urge us with the decree of this Synod, as if the venerable Fathers did not bring themselves into utter discredit by handling Scripture so childishly, or wresting it so shamefully and profanely.
