Doctor of the Church, patron saint of children with disabilities
St. Hilary was a native of Poitiers in Aquitaine. Born and educated a pagan, it was not till near middle age that he embraced Christianity, moved thereto mainly by the idea of God presented to him in the Holy Scriptures. He soon converted his wife and daughter, and separated himself rigidly from all un-Catholic company.
In the beginning of his conversion, St. Hilary would not eat with Jews or heretics, nor salute them by the way; but afterwards, for their sake, he relaxed this severity. He entered Holy Orders, and in 350 was chosen bishop of his native city.
The Arian heresy, under the protection of the Emperor Constantine, was just then in the height of its power, and St. Hilary found himself called upon to support the orthodox cause in several Gallic councils, in which Arian bishops formed an overwhelming majority. He was in consequence accused to the emperor, who banished him to Phrygia. He spent his three years and more of exile in composing his great Treatise on the Trinity and many others works.
In 359, he attended the Council of Seleucia, in which Arians, semi-Arians, and Catholics contended for the mastery. With the deputies of the council he proceeded to Constantinople, and there so dismayed the heads of the Arian party that they prevailed upon the emperor to let him return to Gaul. He traversed Gaul, Italy, and Illyria, wherever he came discomfiting the heretics and procuring triumph of orthodoxy.
After seven or eight years of missionary travel he returned to Poitiers, where he died in peace in 368.
