Faustus

Faustus of Riez (Faustus Reiensis), also called Faustus of Lérins, was a fifth-century monk, abbot, and bishop, and one of the most conspicuous ecclesiastical writers of late antique southern Gaul. The priest-historian Gennadius of Marseille, writing near the end of that century, identifies him as a Briton by birth (Britto). Neither a precise birth year nor a birthplace more specific than Britain is preserved in the early sources, and modern scholars have occasionally asked whether Gennadius’s term might refer to Armorican Brittany rather than the island of Britain; the traditional identification remains Britain. In early adulthood Faustus crossed to the Mediterranean coast of Gaul and entered the island monastery of Lérins, the community founded by Honoratus that had become a principal school of ascetic life and clerical formation in the West. There he was trained in the monastic tradition that looked to the Egyptian desert through the mediation of John Cassian and the Lérins fathers.

He succeeded Maximus as abbot of Lérins when Maximus was made bishop of Riez, an event generally placed in the 430s. As abbot he was remembered for personal austerity and for the defence of the monastery’s discipline and independence. After Maximus’s death Faustus himself was chosen bishop of Riez in Provence, probably around the middle of the fifth century. In that office he took part in the synods and correspondence of the Gallic church. Sidonius Apollinaris, a contemporary bishop and man of letters, wrote to him in terms of respect for his learning and holiness. Faustus was a determined opponent of Arianism among the Visigoths. King Euric, himself an Arian, drove a number of Catholic bishops from their sees; Faustus was exiled around 477 and spent several years away from Riez, returning after Euric’s death in 484.

His lasting reputation is theological. In treatises that include De gratia Dei et libero arbitrio and De Spiritu Sancto he set out a doctrine of grace later labelled Semi-Pelagian: he insisted that divine grace is necessary for salvation, yet he also maintained a real initiative of human free will, especially in the first movement toward faith, and he rejected the more extreme readings of Augustine’s late teaching on predestination and irresistible grace. That position was widely influential in southern Gaul in his own generation. A century later the Second Council of Orange (529) defined the question in a more strictly Augustinian sense, and Faustus’s name thereafter stood under a measure of doctrinal suspicion in the Latin West, even while his personal sanctity continued to be honoured locally. He also left homilies and letters concerned with Trinitarian orthodoxy, monastic virtue, and ordinary pastoral care.

The exact year of his death is not recorded. It is customarily placed in the last decade of the fifth century, at Riez. He was venerated as a saint in the churches of Provence and at Lérins. Different local calendars assigned different days; 28 September is the date most often cited in later martyrologies and summaries. No act of papal canonization from his own age survives; his cult belongs to the period of local episcopal recognition. The place of burial and any later translation of relics are not securely documented in the sources that remain.
