Saint Avitus of Vienne

Bishop, Defender of the Faith
(c. 450–518)

Saint Avitus was born around the year 450 into one of the most distinguished Gallo-Roman families, a family which had already given a bishop to the see of Vienne. He received an excellent classical education and grew up in an atmosphere of both secular culture and Christian piety. When his father Hesychius, who was Bishop of Vienne, died in 490, Avitus was chosen by the clergy and people to succeed him, though he accepted this honour with great reluctance and a genuine sense of his own unworthiness.

As bishop, Avitus proved himself a shepherd of remarkable energy and learning. The greatest challenge of his episcopate was the Arianism which had taken root among the Burgundian kings who ruled the region. These kings denied the full divinity of Christ according to the Arian heresy, and their court was filled with Arian bishops and clergy. Avitus engaged these adversaries not with anger but with patient theological argument, writing letters and treatises that demonstrated the errors of Arianism with great learning and charity.

His greatest achievement was the conversion of Sigismund, the heir to the Burgundian throne. Avitus cultivated a long friendship with this prince, corresponding with him regularly and guiding him by gentle persuasion toward the Catholic faith. When Sigismund finally abjured Arianism and embraced Catholic Christianity around 516, it was a triumph not only for Avitus personally but for the whole Catholic cause in the region. The saint celebrated the occasion with great joy and composed prayers of thanksgiving.

Avitus was also a distinguished man of letters. He composed a long biblical poem in Latin, covering the creation of the world, the fall of Adam, the expulsion from paradise, the deluge, and the crossing of the Red Sea, which was admired throughout the Middle Ages for its learning and beauty. His letters, of which many survive, show him in correspondence with popes, kings, and bishops across the Western world, always concerned with the purity of doctrine and the welfare of souls.

He was present at several important councils and was instrumental in strengthening the bonds of the Burgundian church with Rome. He died around 518, leaving behind him a church that had been greatly strengthened and a region that was moving steadily toward Catholic unity. He is venerated as one of the great bishop-saints of early medieval Gaul.
