St. Hilary

St. Hilary of Poitiers was born around 315 in Poitiers in Gaul and died there in 367. A bishop, Father of the Church, and Doctor of the Church, he is honored as one of the great Western defenders of the divinity of Christ during the Arian controversy. His feast is January 13.

Hilary was born into a pagan or non-Christian family and received a strong classical education. Through study and reflection he came to faith in Christ and was baptized as an adult. His conversion included his family, and he was later chosen bishop of Poitiers by the Christian people. He did not seek controversy, but the crisis over Arianism forced him to become a defender of the Nicene faith.

Arian teaching denied or weakened the full divinity of the Son. Hilary resisted imperial and episcopal pressure to compromise, especially when Catholic bishops such as St. Athanasius were condemned. For his firmness he was exiled to Phrygia by the emperor Constantius II. Exile became a school of theology. In the East, Hilary studied Greek theological language and wrote his great work On the Trinity, explaining the consubstantial divinity of the Father and the Son for Latin-speaking Christians.

Returning to Gaul, he continued to strengthen Catholic bishops and oppose error without losing pastoral concern. He also wrote biblical commentaries and hymns, and he influenced St. Martin of Tours, who founded a monastic community near Poitiers under Hilary’s protection. Hilary’s importance lies in clarity joined to courage: a married convert, bishop, exile, theologian, and pastor who helped the Western Church confess that Jesus Christ is true God from true God.

His influence continued through St. Martin of Tours and through later Latin theology. By giving the West language for the mystery of the Trinity, Hilary helped make the faith teachable in a time of confusion. His sanctity was intellectual, pastoral, and costly because he accepted exile for the truth he preached.
