Moreover now at Hippo-Regius as Presbyter I wrote a book on the Profit of Believing, to a friend of mine who had been taken in by the Manichees, and whom I knew to be still held in that error, and to deride the Catholic school of Faith, in that men were bid believe, but not taught what was truth by a most certain method. This book begins thus, “Si mihi Honorate, unum atque idem videretur esse.” St. Augustin enumerates his book on the Profit of Believing first amongst those he wrote as Presbyter, to which order he was raised at Hippo about the beginning of the year 391. The person for whom he wrote had been led into error by himself, and appears to have been recovered from it, at least if he is the same who wrote to St. Augustin from Carthage about 412, proposing several questions, and to whom St. Augustin wrote his 140th Epistle. Cassiodorus calls him a Presbyter, though at that time he was not baptized. In Ep. 83, St. Augustin speaks of the death of another Honoratus, a Presbyter.
