John Chrysostom. John Chrysostom (347 - 407) was a notable Christian bishop and preacher from the 4th and 5th centuries in Syria and Constantinople. He is famous for eloquence in public speaking and his denunciation of abuse of authority in the Church and in the Roman Empire of the time.
Early tradition says that John was banished to Patmos by the Roman authorities. This tradition is credible because banishment was a common punishment used during the Imperial period for a number of offenses. Among such offenses were the practices of magic and astrology.or other people called Saint John, see Saint John (disambiguation) .
