200 Petilianus said: "Where is the saying of the Lord Christ, ‘Whosoever shall smite you on the right cheek, turn to him the other also'? Where is the patience which He displayed when they spat upon His face, who Himself with His most holy spittle opened the eyes of the blind? Where is the saying of the Apostle Paul, ‘If a man smite you in the face?' Where is that other saying of the same apostle, ‘In stripes above measure, in prisons more frequent, in deaths oft'? He makes mention of the sufferings which he underwent, not of the deeds which he performed. It had been enough for the Christian faith that these things should be done by the Jews: why do you, wretched men, do these others in addition?"
201. Augustine answered: Is it then really so, that when men smite you on the one cheek, you turn to them the other? This is not the report that your furious bands won for you by wandering everywhere throughout the whole of Africa with dreadful wickedness. I would fain have it that men should make a bargain with you, that, in accordance with the old law, you should seek but "an eye for an eye, a tooth for a tooth," instead of bringing out cudgels in return for the words which greet your ears.
