I was informed this is St. John Chrysostom. From the Wikipedia: Saint John Chrysostom (c. 347–407, Greek: Ιωάννης ο Χρυσόστομος, Latin: Ioannes Chrysostomos), archbishop of Constantinople, was an important early father of the church. He is known for his eloquence in preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, the 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.
