Hilary (Hilarius) of Poitiers was Bishop of Poitiers and is a Doctor of the Church. He was sometimes referred to as the "Hammer of the Arians" and the "Athanasius of the W."
Background
Hilary of Poitiers was born at Pictavium, Gaul (modern-day Poitiers, France) either at the end of the 3rd or beginning of the 4th century A.D. His parents were pagans of distinction. His name comes from the Latin word for happy or cheerful. His optional memorial in the General Roman Calendar is 13 January. In the past, when this date was occupied by the Octave Day of the Epiphany, his feast day was moved to 14 January.
Education
Coming from a family of noble birth, Hilary received a liberal education and devoted the early years of his life to the study of philosophy. His search to understand the meaning of existence led him to the examination of the Christian Scriptures.
He received a good education, including what had even then become somewhat rare in the West, some knowledge of Greek. He studied, later on, the Old and New Testament writings, with the result that he abandoned his Neo-Platonism for Christianity.
Career
The Christians of Poitiers so respected Hilary that about 350 or 353, they unanimously elected him their bishop. At that time Arianism threatened to overrun the Western Church, Hilary undertook to repel the disruption. One of his first steps was to secure the excommunication, by those of the Gallican hierarchy who still remained orthodox Christians, of Saturninus, the Arian Bishop of Arles, and of Ursacius and Valens, two of his prominent supporters.
About the same time, Hilary wrote to Emperor Constantius II a remonstrance against the persecutions by which the Arians had sought to crush their opponents.
Hilary spent nearly four years in exile, although the reasons for this banishment remain obscure. The traditional explanation is that Hilary was exiled for refusing to subscribe to the condemnation of Athanasius and the Nicene faith. More recently several scholars have suggested that political opposition to Constantius and support of the usurper Silvanus may have led to Hilary's exile.
While in Phrygia, however, he continued to govern his diocese, as well as writing two of the most important of his contributions to dogmatic and polemical theology: the De synodis or De fide Orientalium, an epistle addressed in 358 to the Semi-Arian bishops in Gaul, Germany and Britain, analyzing the views of the Eastern bishops on the Nicene controversy. In reviewing the professions of faith of the Oriental bishops in the Councils of Ancyra, Antioch, and Sirmium, he sought to show that sometimes the difference between certain doctrines and orthodox beliefs was rather in the words than in the ideas, which led to his counseling the bishops of the West to be more reserved in their condemnation.
Hilary also attended several synods during his time in exile, including the council at Seleucia (359) which saw the triumph of the homoion party and the forbidding of all discussion of the divine substance.
In 360, Hilary tried unsuccessfully to secure a personal audience with Constantius, as well as to address the council which met at Constantinople in 360. When this council ratified the decisions of Ariminum and Seleucia, Hilary responded with the bitter In Constantium, which attacked the Emperor Constantius as Antichrist and persecutor of orthodox Christians. Hilary's urgent and repeated requests for public debates with his opponents, especially with Ursacius and Valens, proved at last so inconvenient that he was sent back to his diocese, which he appears to have reached about 361, within a very short time of the accession of Emperor Julian.
On returning to his diocese in 361, Hilary spent most of the first two or three years trying to persuade the local clergy that the homoion confession was merely a cover for traditional Arian subordinationism. Thus, a number of synods in Gaul condemneded the creed promulgated at Council of Ariminium (359).
In about 360 or 361, with Hilary's encouragement, Martin, the future bishop of Tours, founded a monastery at Ligugé in his diocese.
In 364, Hilary extended his efforts once more beyond Gaul. He impeached Auxentius, bishop of Milan, a man high in the imperial favour, as heterodox. Emperor Valentinian I accordingly summoned Hilary to Milan to there maintain his charges. However, the supposed heretic gave satisfactory answers to all the questions proposed. Hilary denounced Auxentius as a hypocrite as he himself was ignominiously expelled from Milan. Upon returning home, Hilary in 365, published the "Contra Arianos vel Auxentium Mediolanensem liber", describing his unsuccessful efforts against Auxentius. He also published the Contra Constantium Augustum liber, accusing the lately deceased emperor as having been the Antichrist, a rebel against God, "a tyrant whose sole object had been to make a gift to the devil of that world for which Christ had suffered."
According to Jerome, Hilary died in Poitiers in 367.
Religion
St. Hilary had a great interest in theological concerns. He seemed to be a man of a kindly and charitable disposition, but this did not keep him from vigorously defending the Church against Aryanism. Embroiled in this famous controversy, he made some enemies who succeeded in getting him exiled to Phrygia in Asia Minor.
Connections
He was married, and had a daughter named Apra.
