Saint Hilary of Poitiers (310-315 AD) converted from paganism to Christianity, becoming a staunch defender of the Trinity. As Bishop of Poitiers, he opposed Arianism, was exiled for defending Athanasius, and wrote “De Trinitate.” Known as the “Athanasius of the West,” he emphasized gentleness and reverence in his teachings. Hilary died in 367, leaving a legacy of theological works and hymns.
