John of Damascus was the greatest theologian and poet of the Greek Church. His active life belonged to the eighth century, but the exact dates of his birth and death are unknown. His work on theology, Doctrines of the Orthodox Church, is still a standard textbook in the Eastern Church. He was famous as a philosopher and as an opponent of the Iconoclasts of his time. Late in life he was ordained priest of the Church at Jerusalem.
