St. John Chrysostom (349-407).  Born at Antioch, after a brilliant course of studies, he led a life of austerity.  Ordained priest, he became Bishop of Constantinople and showed himself to be a true pastor by striving to reform the morals both of his clergy and the people.  He incurred the hatred of the Imperial Court, his work was undermined because eof jealousy, and he was twice sent into exile where he died at Comana in Pontus.  Because of his sermons and writings explaining the faith, he became known as John of the Golden Mouth.
