Nestorianism is a Christological doctrine that emphasizes the disunion between the human and divine natures of Jesus. It was advanced by Nestorius (386–450), Patriarch of Constantinople from 428–431, influenced by Nestorius' studies under Theodore of Mopsuestia at the School of Antioch. Nestorius's teachings brought him into conflict with other prominent church leaders, most notably Cyril of Alexandria, who criticized especially his rejection of the title Theotokos ("Bringer forth of God") for the Virgin Mary. Nestorius and his teachings were eventually condemned as heretical at the First Council of Ephesus in 431 and the Council of Chalcedon in 451, leading to the Nestorian Schism, in which churches supporting Nestorius broke with the rest of the Christian Church. Following that, many of Nestorius's supporters relocated to the Sasanian Empire, where they affiliated with the local Christian community, known as the Church of the East. Over the next decades the Church of the East became increasingly Nestorian in doctrine, leading to it becoming known alternately as the Nestorian Church.
CHURCH OF THE EAST (WIKI)
The Church of the East (Syriac: ܥܕܬܐ ܕܡܕܢܚܐ ʿĒ(d)tāʾ d-Maḏn(ə)ḥāʾ), also known as the Nestorian Church,[note 1] was a Christianchurch within the Syriac tradition of Eastern Christianity. It was the Christian church of the Sasanian Empire, and quickly spread widely through Asia. Between the 9th and 14th centuries it represented the world's largest Christian church in terms of geographical extent, with dioceses stretching from the Mediterranean Sea to China and India. Several modern churches claim continuity with the historical Church of the East.
The Church of the East was headed by the Patriarch of the East, continuing a line that, according to tradition, stretched back to theApostolic Age. Liturgically, the church adhered to the East Syrian Rite, and theologically, it adopted the doctrine of Nestorianism, which emphasizes the distinctness of the divine and human natures of Jesus. This doctrine and its namesake, Nestorius (386–451), were condemned by the Council of Ephesus in 431, leading to the Nestorian Schism and a subsequent exodus of Nestorius' supporters to Sasanian Persia. The existing Christians in Persia welcomed these refugees and gradually adopted Nestorian doctrine by the 5th century, leading the Church of Persia to be known alternately as the Nestorian Church.
