St. Hilary of Poitiers


Hilary, born in the early 4th century and elected bishop of Potiers, France around the year 353 AD, became the leading and most respected Latin theologian of his age. Seeking to immunize the church against the infection of the Arian heresy, which denied the divinity of Christ, he wrote an extensive treatise On the Trinity which is perhaps his most famous work. For his trouble, he was exiled by the Emperor, an Arian sympathizer. St. Hilary, one of the Fathers of the Church,  died in 367 and was proclaimed a Doctor of the Church fifteen centuries later by Pope Pius IX.  (bio by Dr. Italy)
