John Chrysostom (c. 347 – 14 September 407) was an important Early Church Father who served as archbishop of Constantinople. He is known for his preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, Divine Liturgy of Saint John Chrysostom, and his ascetic sensibilities. The epithet Χρυσόστομος (Chrysostomos, anglicized as Chrysostom) means “golden-mouthed” in Greek and denotes his celebrated eloquence. [Description from Wikipedia]
