Three Books of Augustine in Answer to the Letters of Petilian the Donatist (en Inglés) - St. Augustine;A M Overett;J R King

Written c. 400 A.D., some say 398 A.D., but Augustin places it sometime after the treatise on Baptism: Retractt.Bk. ii. xxv. From the same, we gather the following points as to the origin of this treatise: Before A. had finished his books on the Trinity and his word for word commentary on Genesis, a reply to a letter which Petilian had addressed to his followers, only a small part of which however had come into A.’s hands, demanded immediate preparation. This constitutes Book First. Subsequently the whole document was obtained, and he was engaged in preparing the second Book, c. 401; but even before the full treatise of Petilian had been secured, the latter had obtained A.’s first book, and afterwards put an epistle abusive of A. in circulation. The answer to this latter is Book Third, c. 402. Petilian was originally an advocate. The opponents charged him with having become a Donatist by compulsion, with assuming the title of Paraclete, and with endeavoring to prevent all access on their part to his writings.
