St. Celestine I, Pope of Rome

In the first half of the fifth century, when the Byzantine throne was owned by Theodosius the Younger, a native of an educated environment ascended to the Roman cathedra. Celestine mastered ancient philosophy, but the main thing for him was the interpretation of the Bible and dogmatics. A life without vices and a reputation as a connoisseur of faith provided support for both the clergy and the laity. Celestine’s predecessor Boniface I died in 422, after which the election of a new pontiff took place.

At that time, the movement of Nestorius was gaining strength, denying the unity of the divine and human nature of Christ. Having assembled a local council in Rome, Celestine publicly denied these views. Then he wrote a message to Cyril of Alexandria: if within 10 days Nestorius does not repent, then deprivation of rank and anathema will follow.
