Nor indeed was there any necessity for my refuting these, except that I see you still in dubiety about the word of the truth. For though yourself prudent, you endure fools gladly. Otherwise you would not have been moved by senseless men to yield yourself to empty words, and to give credit to the prevalent rumor wherewith godless lips falsely accuse us, who are worshippers of God, and are called Christians, alleging that the wives of us all are held in common and made promiscuous use of; and that we even commit incest with our own sisters, and, what is most impious and barbarous of all, that we eat human flesh. ^[640] But further, they say that our doctrine has but recently come to light, and that we have nothing to allege in proof of what we receive as truth, nor of our teaching, but that our doctrine is foolishness. I wonder, then, chiefly that you, who in other matters are studious, and a scrutinizer of all things, give but a careless hearing to us. For, if it were possible for you, you would not grudge to spend the night in the libraries.
