Saint Eustathius of Antioch was a fourth-century bishop and a strong defender of the Catholic faith during the Arian controversy. Born at Side in Pamphylia, he became Bishop of Antioch and worked to preserve the Church’s confession of the true divinity of the Son.
Because of his opposition to Arianism, he was falsely accused and deposed by a hostile synod. He died in exile at Trajanopolis in Thrace, remaining faithful to the Church and to the orthodox faith he had defended.
