Homiles on the Gospel of St. John and the Epistle of the Hebrews by Saint John Chrysostom

According to Wikipedia: "Saint John Chrysostom (c. 347–407, Greek: Ιωάννης ο Χρυσόστομος), archbishop of Constantinople, was an important Early Church Father. He is known for his eloquence in preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, the Divine Liturgy of St. John Chrysostom, and his ascetic sensibilities. After his death (or, according to some sources, during his life) he was given the Greek surname chrysostomos, meaning "golden mouthed", rendered in English as Chrysostom.
