John Chrysostom was a prominent theologian, writer, and bishop who lived from approximately 347 to 407. Born in Antioch and raised by a devout mother, he studied rhetoric before practicing asceticism as a hermit. After being ordained a deacon in 381 and serving as a priest in Antioch, he was appointed Archbishop of Constantinople in 397. He is widely recognized as one of the four Great Greek Fathers and one of the Three Holy Hierarchs.
