John Chrysostom, archbishop of Constantinople, 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.
