A Christian church that came into existence after the condemnation of Nestorius at the Council of Ephesus in 431. Through the efforts of Ibas, Bishop of Ephesus from 435, and Barsumas, Bishop of Nisibis from 457, Nestorianism was developed into a rounded theology and transported to Persia and Asia Minor, where a small but influential sect was founded. The Nestorian Church survives to the present day under the name of Assyrian Christian.
