This teaching originated with Nestorius (d. c. 451), patriarch of Constantinople and representative of Antiochene theology. Nestorius emphasized both the complete humanity and divinity of Christ. He was concerned to maintain the distinction between the two natures of Christ and argued that the divinity of Christ not be allowed to overwhelm his humanity in the eyes of the church. This teaching was rejected particularly by Alexandrian theologians who argued that Nestorius had divided Christ into two beings. Nestorianism was rejected at the Council of Ephesus (431), one of the seven ecumenical councils. Nestorianism is also one of the alternatives rejected in the "Definition of Faith" adopted at the Council of Chalcedon to settle the early Christological controversies. Some Christians in Persia and Syria continue to hold the Nestorian position to the present.
