Just a taste of the information on Chrysostom over at For All the Saints:
John, whose epithet “Chrysostom” means “golden-mouthed”, was one of the greatest preachers in the history of the Church. People flocked to hear him, and they often dismayed him by applauding his sermons. His eloquence was accompanied by an acute sensitivity to the needs of his people. He saw preaching as an integral part of pastoral care, and as a medium of teaching.
O God, you gave your servant John Chrysostom grace eloquently to proclaim your righteousness in the great congregation, and fearlessly to bear reproach for the honor of your Name: Mercifully grant to all bishops and pastors such excellence in preaching, and faithfulness in ministering your Word, that your people may be partakers with them of the glory that shall be revealed; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
