St. Augustine enumerates his book on the Profit of Believing first among 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. Augustine from Carthage about 412, proposing several questions, and to whom St. Augustine wrote his 140th Epistle.
