John Chrysostom PB

John Chrysostom could perhaps be called an enigma of his day. He had neither desire for politics nor ambition for ecclesiastical advancement. He preferred to live the simple life of an ascetic and had no cravings for fame, riches, or luxuries that came with life in the metropolitan cities of his day. However in God's providence m, he is now recognised as one of the Doctors of the Church. What gas made him so revered and remembered?
