Nicene and Post-Nicene Fathers, Vol. IV: Writings in Conn...
Chapter 50.—115. Petilianus said: "But that we may destroy your arguments one by one, if you call yourselves by the name of priests, it was said by the Lord God, through the mouth of His prophet, ‘The vengeance of the Lord is upon the false priests.’"
116. Augustin answered: Seek rather what you may say with truth, not whence you may derive abusive words; and what you may teach, not what reproaches you may cast in our teeth.
