St John Chrysostom (349 - 407)
He was born in Antioch. After a thorough education, he took up the ascetic life. He was ordained to the priesthood, and became a fruitful and effective preacher.
He was elected Patriarch of Constantinople in 397, and was energetic in reforming the ways of the clergy and the laity alike. He incurred the displeasure of the Emperor and was twice forced into exile. When the second exile, to Armenia, had lasted three years, it was decided that he should be sent still further away, but he died on the journey, worn out by his hardships.
His sermons and writings did much to explain the Catholic faith and to encourage the living of the Christian life: his eloquence earned him the surname “Chrystostom” (the Greek for “golden mouth”).
