Proclus of Constantinople

Saint Proclus (died July 446 or 447) was an Archbishop of Constantinople. He is venerated as a saint in the Catholic Church and the Eastern Orthodox Church.

The friend and disciple of Saint John Chrysostom, Proclus became secretary to Archbishop Atticus of Constantinople (406–425). who ordained him deacon and priest. Atticus' successor, Sisinnius I (426–427), consecrated him Bishop of Cyzicus, but the people there refused to receive him, and he remained at Constantinople. On the death of Sisinnius, the famous Nestorius succeeded as Archbishop of Constantinople (428–431), and early in 429, on a festival of the Theotokos (Virgin Mary), Proclus preached his celebrated sermon on the Incarnation, which was later inserted in the beginning of the of the Council of Ephesus.

When Archbishop Maximianus (431–434) died on Great and Holy Thursday, Proclus was immediately enthroned by the permission of the Emperor Theodosius II and the bishops gathered at Constantinople. His first care was the funeral of his predecessor, and he then sent to both Patriarchs Cyril of Alexandria and John of Antioch the usual synodical letters announcing his appointment, both of whom approved of it.
