Answer to Letters of Petilian, Bishop of Cirta
Book II › Chapter 9
21. Petilianus said: "Hemmed in, therefore, by these offenses, you cannot be a true bishop."
22. Augustine answered: By what offenses? What have you shown? What have you proved? And if you have proved charges on the part of I know not whom, what has that to do with the seed of Abraham, in which all the nations of the earth are blessed?
