Caesarius of Arles

Caesarius of Arles (c. 470–542) served as Archbishop of Arles from 502 until his death, making him the most influential churchman in Gaul during the period of Visigothic and then Ostrogothic rule. He presided over the Council of Orange in 529, whose canons — affirming Augustine's teaching on grace and condemning semi-Pelagianism — shaped Western Christian doctrine on salvation for centuries. He was a prolific and accessible preacher whose hundreds of sermons were deliberately composed in plain Latin for ordinary congregations, and he promoted the practice of the laity following along in writing. He founded a convent for women in Arles, placing his sister Caesaria as its first abbess, and composed one of the earliest Western monastic rules specifically for nuns. He was venerated as a saint almost immediately after his death, and a biography was composed by his disciples within a decade; formal canonization procedures of the kind later governed by the papacy did not yet exist in his era.
