Nestorius, in
Greek, Νεστόριος (
c. 386–c. 451) was
Archbishop of Constantinople from
10 April 428 to
22 June 431. He received his clerical training as a pupil of
Theodore of Mopsuestia in
Antioch and gained a reputation for his sermons that led to his enthronement by
Theodosius II as Archbishop following the death of
Sisinnius I in 428.
Nestorius is considered the originator of the
Christological position known as
Nestorianism, which was eventually declared
heretical; it emerged when he began preaching against the title
Theotokos (in
Greek, Θεοτόκος) or
Mother of God,
God-Bearer, an appellation for
Mary, the mother of Jesus. He quickly met with antagonism from the bishop, Saint
Cyril of Alexandria. Alongside the Christological debate, other factors were to come into play in the controversy that would ensue, including a political struggle between the supporters of the See of Alexandria and the See of Antioch, the influence of the Emperor over the See of Constantinople, and the patriarchal primacy of the Pope.
The theological debate centered on the use of the title "Mother of God" (
Theotokos/Θεοτόκος) for
the Virgin Mary, which Nestorius did not recognize, preferring in his sermons, "Mother of Christ" (
Christotokos/Χριστοτόκος/) on the grounds that the former title compromised
Jesus' humanity. Cyril countered that it was Nestorius who was actually denying the reality of the
Incarnation, by making Jesus Christ into two different persons, one human and one divine, in one body.

The Emperor
Theodosius II (
401–450) was eventually induced to convoke a general church council, sited at Ephesus, itself a special seat for the veneration of Mary, where the
theotokos formula was popular. The Emperor gave his support to the Archbishop of Constantinople, while
Pope Celestine I was in agreement with Cyril.
Cyril took charge of the
Council of Ephesus in
431, opening debate before the long-overdue contingent from
Antioch could arrive.
The council deposed Nestorius and declared him a
heretic. In Nestorius' own words,
When the followers of Cyril saw the vehemence of the emperor… they roused up a disturbance and discord among the people with an outcry, as though the emperor were opposed to God; they rose up against the nobles and the chiefs who acquiesced not in what had been done by them and they were running hither and thither. And… they took with them those who had been separated and removed from the monasteries by reason of their lives and their strange manners and had for this reason been expelled, and all who were of heretical sects and were possessed with fanaticism and with hatred against me. And one passion was in them all, Jews and pagans and all the sects, and they were busying themselves that they should accept without examination the things which were done without examination against me; and at the same time all of them, even those that had participated with me at table and in prayer and in thought, were agreed… against me and vowing vows one with another against me… In nothing were they divided.
In the following months, 17
bishops who supported Nestorius' doctrine were removed from their sees, and his principal supporter,
John I of Antioch, succumbed to imperial pressure and abandoned Nestorius in March
433. On August 3,
435, Theodosius II, who had supported Nestorius' appointment, bowed to the influence of his sister
Pulcheria in issuing an imperial edict that exiled Nestorius to a
monastery in the Great Oasis of Hibis (
al-Khargah), in Egypt, securely within the diocese of Cyril. In East and West, Nestorius' writings were burnt wherever they could be found. They survive mainly in
Syriac.
The incident caused a split within the church, and led to the creation of separate
Nestorian churches that would flourish throughout the
Middle East and
central Asia.
After 1,500 years of stigmatization as a heretic, a book written by Nestorius was discovered in 1895, known as the
Bazaar of Heracleides, written towards the end of his life, in which he explicitly denies the heresy for which he was condemned, instead affirming of Christ "the same one is twofold" — an expression that some consider similar to the formulation of the
Council of Chalcedon. Nestorius's earlier surviving writings, however, including his letter written in response to Cyril's charges against him, contain material that seems to support charges that he held that Christ had two persons. Thus, whether Nestorius was actually a Nestorian is still a matter of debate.
Nestorius is deeply venerated in the
Assyrian Church of the East as a
saint, the Syriac for 'Saint Nestorius' being
Mar Nestorios.
