Bishop Proclus of Constantinople/Istanbul (d. AD 446)
Proclus was a close friend and disciple of John Chrysostom, who ordained him a deacon and elder in Constantinople. Proclus opposed the teaching of Nestorius, faithfully upheld Nicene orthodoxy, and supported Mary being called Theotokos, the Mother of God. During the reign of emperor Theodosius II, Proclus became Constantinople’s bishop and served for twelve years, from 434 to 446. In 438, Proclus assisted in bringing the physical remains of John Chrysostom back to Constantinople from Comana (modern Tokat) where he had died in exile. John’s remains were put in the Church of the Holy Apostles. Proclus was known as a wise, moderate, and peace-making bishop. He died in 446.
