Catholic Encyclopedia (1913)/St. Possidius
Bishop of Calama in Numidia, author of a short life of St. Augustine and of an indiculus or list of St. Augustine's writings. The dates of his birth and death are unknown; he was alive and in exile in 437 according to Prosper, who, in his "Chronicle", records that Possidius and two other bishops were persecuted and expelled from their sees by the Vandal king, Genseric, who was an Arian. Possidius (Vita S. Augustini, xxxi), after describing the death of St. Augustine, speaks of his unbroken friendship with him for forty years. He also, speaking of himself in the third person, lets it be known that he was one of the clergy of St. Augustine's monastery (ibid., xii). The date of his promotion to the episcopate was, according to Tillemont, about 397. He followed St. Augustine's example and established a monastery at Calama. At a council, held at Carthage, Possidius challenged Crispinus, the Donatist Bishop of Calama, to a public discussion which the latter declined. Shortly afterwards one of Crispinus's clergy, bearing the same name as his bishop, attempted to assassinate Possidius. Legal proceedings were instituted against Crispinus, the bishop, who refused to punish his presbyter. He was proved to be a heretic and was heavily fined, but at the intercession of Possidius the fine was not exacted ("Vita", xii; St. Augustine, "Ep.", cv, 4; "Contra Crescon.", III, xlvi). In 407, Possidius served, with St. Augustine and five other bishops, on a committee appointed to adjudicate upon some ecclesiastical matter, the particulars of which are not known. In 408 he nearly lost his life in a riot stirred up by the pagans at Callama (St. Augustine, "Epp.", xc, xci, xciii). In 409 he was one of four bishops deputed to go to Italy to obtain the protection of the emperor against the Donatists. He was one of the seven bishops chosen to represent the Catholic party at the "Collatio" of 411. In 416 he assisted at the Council of Milevum, where fifty-nine Numidian bishops addressed a synodal letter to Innocent I, asking him to take action against Pelagianism. He joined with St. Augustine and three other bishops in a further letter to Innocent on the same subject, and was at the conference between St. Augustine and the Donatist Emeritus. When the Vandals invaded Africa, he fled to Hippo and was present at the death of St. Augustine (430). His "Vita S. Augustini", composed before the capture of Carthage (439), is included in all editions of the works of St. Augustine, and also printed in Hurter's "Opusc. SS. Patr.". His indiculus will be found in the last volume of Migne's edition of the works of St. Augustine and in the tenth volume of the Benedictine edition.
