Today is the feast day of St John Chrysostom, Bishop and Doctor of the Church. The introductory note in the Divine Office says:
Born at Antioch about the year 439. After a brilliant course of studies he began to lead a life of austerity. He was ordained priest and laboured in preaching, with great fruit. In 397 he became Bishop of Constantinople and showed himself a true pastor, striving to reform the morals of both clergy and people. He incurred the hatred of the imperial court and his work was undermined because of jealousy, and twice he was sent into exile. Overcome by exhaustion he died at Comana in Pontus on 14 September 407. Because of his sermons and writings to explain the faith and to encourage the practice of Christian life he was called John of the Golden Mouth.Under the old calender, his feast day was 27 January.
