FAUSTUS OF RIEZ, SAINT

born c. 400, , Roman Britain died c. 490, ; feast day in Southern France, September 28 bishop of Riez, Fr., who was one of the chief exponents and defenders of Semi-Pelagianism (q.v.). In the early 5th century Faustus went to southern Gaul, where he joined the newly founded monastic community on the les de Lrins (off the southeast coast of present France), of which he became the third abbot c. 433. After his election as bishop of Riez (c. 458) he played a leading role in the ecclesiastical life of 5th-century Gaul. Faustus' De gratia gave the final form to Semi-Pelagianism. He taught that God cannot interfere with man's freedom either before or after his conversion to Christianity, and that all faith is rooted in grace because human freedom itself is a form of grace. His doctrine was rejected, however, by the second Council of Orange (France) in 529. His controversial orthodoxy prevents his veneration by the universal church.
