Bishop of Arles, France, and friend and relative of St. Honoratus. He was born to a noble family in Lorraine and was successful, although he gave up his secular career to join St. Honoratus at Lerins Abbey. When Honoratus died after being named the bishop of Arles, Hilary was chosen as his successor in 429. He was known for his austerities, his aid to the poor, and for ransoming captives. On two occasions Hilary became embroiled in controversies with Pope St. Leo I the Great, but they were reconciled, and Hilary’s sanctity brought him great veneration.
