Nestorianism - Nestorian Schism and Early History

Nestorian Schism and Early History

Nestorianism became a distinct sect following the Nestorian Schism, beginning in the 430s. Nestorius had come under fire from Western theologians, most notably Cyril of Alexandria. Cyril had both theological and political reasons for attacking Nestorius; on top of feeling that Nestorianism was an error against true belief, he also wanted to denigrate the head of a competing patriarchate. Cyril and Nestorius asked Pope Celestine I to weigh in on the matter. Celestine found that the title Theotokos was orthodox, and authorized Cyril to ask Nestorius to recant. Cyril, however, used the opportunity to further attack Nestorius, who pleaded with Emperor Theodosius II to call a council so that all grievances could be aired.

In 431 Theodosius called the First Council of Ephesus. However, the council ultimately sided with Cyril, holding that Christ is one subsistence and nature, and that the Virgin Mary is the mother of God. The council accused Nestorius of heresy, and deposed him as patriarch. Nestorianism was officially anathematized, a ruling reiterated at the Council of Chalcedon in 451. However, a number of churches, particularly those associated with the School of Edessa, supported Nestorius – though not necessarily his doctrine – and broke with the churches of the West. Many of Nestorius' supporters relocated to Sassanid Persia, home to a vibrant but persecuted Christian minority.
