John Chrysostom (/ˈkrɪsəstəm, krɪˈsɒstəm/; Greek: Ἰωάννης ὁ Χρυσόστομος; 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, the 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. Chrysostom was among the most prolific authors in the early Christian Church, although both Origen of Alexandria and Augustine of Hippo exceeded Chrysostom.
