And he produces a second illustration to our disadvantage, saying that “our teacher acts like a drunken man, who, entering a company of drunkards, should accuse those who are sober of being drunk.” But let him show, say from the writings of Paul, that the apostle of Jesus gave way to drunkenness, and that his words were not those of soberness; or from the writings of John, that his thoughts do not breathe a spirit of temperance and of freedom from the intoxication of evil. No one, then, who is of sound mind, and teaches the doctrines of Christianity, gets drunk with wine; but Celsus utters these calumnies against us in a spirit very unlike that of a philosopher. Moreover, let Celsus say who those “sober” persons are whom the ambassadors of Christianity accuse. For in our judgment all are intoxicated who address themselves to inanimate objects as to God. And why do I say “intoxicated?” “Insane” would be the more appropriate word for those who hasten to temples and worship images or animals as divinities. And they too are not less insane who think that images, fashioned by men of worthless and sometimes most wicked character, confer any honour upon genuine divinities.
