Saint John Chrysostom
St. John Chrysostom (the name means "golden mouthed") was one of the most famous preachers and reformers of the second half of the fourth century. He was a priest in his native city of Antioch, Syria, and later became Patriarch of Constantinople. Beginning in 390, he preached a famous series on the New Testament, including ninety sermons on Matthew, eighty-eight on John, and thirty-two on Romans. His reforms to purify the church brought him banishment; he died at age fifty in the year 407 during a forced march into exile.
