Bishop of Carthage, of venerable memory, but known for being the first to maintain the necessity of re-baptizing all heretics. (Vincent. Lirinens. Commonit. 1.9.) St. Cyprian regarded this opinion as the correction of an error (S. Augustin. De Baptismo, 2.7, vol. ix. p. 102, ed. Bened.), and St. Augustine seems to imply he defended his error in writing. (Epist. 93, c. 10.) He held the Council of 70 Bishops at Carthage about A. D. 200 (Vulg. A. D. 215, Mans. A. D. 217) on the subject of Baptism. Though he erred in a matter yet undefined by the Church, St. Augustine notices that neither he nor St. Cyprian thought of separating from the Church. (De Baptismo, 3.2, p. 109.)
