Celestine the Bishop

Celestine, bishop of Rome, addressed a volume to the churches of the East and the West. In it he gave an account of the synod’s decree against the Nestorius mentioned above, and maintained that while there are two complete natures in Christ, the person of the Son of God is to be regarded as one. Nestorius was shown to be opposed to this view. Sixtus, Celestine’s successor, likewise wrote on the same subject, to the same Nestorius and to the Eastern bishops, setting out the views of the Western bishops against his error. [a]
