Faustus of Riez
Bishop of Riez
Feast: 28 September (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Faustus, born in Britain, entered the monastery of Lérins under his holy mother's influence and became its abbot in 432, famous for his preaching and stern asceticism. As Bishop of Riez he kept his monastic life and founded many monasteries.
He was the best-known defender of the teaching later called Semipelagianism, which the Church did not accept. He died between 490 and 495 with a reputation for holiness; his own flock regarded him as a saint and built a basilica in his honour.
The miracles
He was honoured as a saint by his own flock at Riez; the Catholic Encyclopedia does not describe a wider recognition.
Why that counted as sanctity
An ascetic abbot and bishop revered by his own people.
