First Council of Ephesus - Aftermath

Aftermath

The events created a major schism between the followers of the different versions of the council, which was only mended by difficult negotiations. The factions that supported John of Antioch acquiesced in the condemnation of Nestorius and, after additional clarifications, accepted the decisions of Cyril's council. However, the rift would open again during the debates leading up to the Council of Chalcedon.

Persia had long been home to a Christian community that had been persecuted by the Zoroastrian majority, which had accused it of Roman leanings. In 424, the Persian Church declared itself independent of the Byzantine and all other churches, in order to ward off allegations of foreign allegiance. Following the Nestorian Schism, the Persian Church increasingly aligned itself with the Nestorians, a measure encouraged by the Zoroastrian ruling class. The Persian Church became increasingly Nestorian in doctrine over the next decades, furthering the divide between Christianity in Persia and in the Roman Empire. In 486 the Metropolitan of Nisibis, Barsauma, publicly accepted Nestorius' mentor, Theodore of Mopsuestia, as a spiritual authority. In 489 when the School of Edessa in Mesopotamia was closed by Byzantine Emperor Zeno for its Nestorian teachings, the school relocated to its original home of Nisibis, becoming again the School of Nisibis, leading to a wave of Nestorian immigration into Persia. The Persian patriarch Mar Babai I (497–502) reiterated and expanded upon the church's esteem for Theodore, solidifying the church's adoption of Nestorianism.
