Nestorius (pron.: //; in Greek: Νεστόριος; c. 386 – 450) was Archbishop of Constantinople from 10 April 428 to August 431 (when the emperor Theodosius II confirmed his condemnation by the Cyrillian faction at Ephesus on 22 June). His teachings included a rejection of the long-used title of Theotokos ("Mother of God") for the Virgin Mary, and were understood by many to imply that he did not believe that Christ was truly God. However, Nestorius actually was concerned that the "Theotokos" cult was dangerously close to venerating Mary as a goddess. This brought him into conflict with other prominent churchmen of the time, most notably Cyril of Alexandria, who accused him of heresy. Nestorius sought to defend himself at the First Council of Ephesus in 431, but instead he found himself formally condemned for heresy by a majority of the bishops and subsequently removed from his see. On his own request he retired to his former monastery in or near Antioch. In 435 Theodosius II sent him into exile in Upper Egypt, where he lived on till 450, strenuously defending his orthodoxy. His last major defender within the Roman Empire, Theodoret of Cyrrhus, finally agreed to anathematize him in 451 (during the Council of Chalcedon); from then on he had no defenders within the empire. But the Church of the East (that is, the Church in eastern Mesopotamia and Persia, under Sassanian rule) never accepted his condemnation. This led later to western Christians giving the name the 'Nestorian Church' to the Church of the East (the modern Assyrian Church of the East), even though it never regarded him as an authoritative teacher. The discovery and publication of his 'Book [or Bazaar] of Heraclides at the beginning of the 20th century led to a reassessment of his theology in western scholarship. It is now generally agreed that his ideas were not far from those that eventually emerged as orthodox, but the orthodoxy of his formulation of the doctrine of Christ is still controversial. This is due to the fact that the Second Council of Constantinople of AD 553 confirmed the validity of the condemnation of Nestorius, refuting the impius letter of Iba that affirms that Nestorius was condemned without the due inquiry.
Nestorius was born around 381/386 in Germanicia in the Roman province of Syria (now Kahramanmaraş in Turkey). 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.
Nestorian controversy 
Shortly after his arrival in Constantinople, Nestorius became involved in the disputes of two theological factions, which differed in their Christology. Nestorius tried to find a middle ground between those that emphasized the fact that in Christ God had been born as a man, insisted on calling the Virgin Mary Theotokos (Greek: Θεοτόκος, "God-bearer"), and those that rejected that title because God as an eternal being could not have been born. Nestorius suggested the title Christotokos (Χριστοτόκος, "Christ-bearer"), but did not find acceptance on either side.
Nestorius believed that no union between the human and divine were possible. If such a union of human and divine occurred, Nestorius believed that Christ could not truly be con-substantial with God and con-substantial with us because he would grow, mature, suffer and die (which he said God cannot do) and also would possess the power of God that would separate him from being equal to humans.
Eusebius, a layman who later became the bishop of the neighbouring Dorylaeum was the first to accuse Nestorius of heresy but his most forceful opponent was Patriarch Cyril of Alexandria. Cyril appealed to Celestine of Rome to make a decision on Nestorius; and Celestine delegated to Cyril the job of excommunicating Nestorius if he did not change his teachings in ten days. Nestorius's opponents charged him with detaching Christ's divinity and humanity into two persons existing in one body, thereby denying the reality of the Incarnation. This heresy came to be known as Nestorianism.
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 and his wife supported Nestorius while Pope Celestine I supported Cyril.
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.
But while the council was in progress, John I of Antioch and the eastern bishops arrived, and were furious to hear that Nestorius had already been condemned. They convened their own synod, at which Cyril was deposed. Both sides then appealed to the emperor. Initially the imperial government ordered both Nestorius and Cyril deposed and exiled. However, Cyril was eventually allowed to return after bribing various courtiers.
Later events 
In the following months, 17 bishops who supported Nestorius' doctrine were removed from their sees. Eventually, John I of Antioch was obliged to abandon Nestorius in March 433. On August 3, 435, Theodosius II issued an imperial edict that exiled Nestorius from the monastery in Antioch in which he had been staying to a monastery in the Great Oasis of Hibis (al-Khargah), in Egypt, securely within the diocese of Cyril. The monastery suffered attacks by desert bandits, and Nestorius was injured in one such raid. Nestorius seems to have survived there until at least 450 (given the evidence of The Book of Heraclides), though we have no knowledge of when after this date he died.
Very few of Nestorius' writings survive. There are several letters preserved in the records of the Council of Ephesus, and fragments of a few others; about thirty sermons are extant, mostly in fragmentary form. The only complete work we have is the lengthy defence of his theological position, called The Book of Heraclides, written in exile at the Oasis, which survives in Syriac translation. This must have been written after 450, as he knows of the death of the Emperor Theodosius II (29 July 450).
Though Nestorius had been condemned by the church, including by Syrians, there remained a faction loyal to him and his teachings. Following the Nestorian Schism and the relocation of many Nestorian Christians to Persia, Nestorian thought became ingrained in the native Christian community, known as the Church of the East, to the extent that it was often known as the "Nestorian Church". In modern times the Assyrian Church of the East, a modern descendant of the historical Church of the East, reveres Nestorius as a saint, although the modern church does not subscribe to the entirety of the Nestorian doctrine as it has traditionally been understood in the West. Parts of the doctrine were explicitly repudiated by Patriarch Mar Dinkha IV on the occasion of his accession in 1976.
In the Roman Empire, the doctrine of Monophysitism developed in reaction to Nestorianism. This new doctrine asserted that Christ had but one nature, his human nature being absorbed into his divinity. This doctrine was condemned at the Council of Chalcedon, and misattributed to the non-Chalcedonian churches. Today it is condemned as heresy in the modern Oriental Orthodox churches.
Bazaar of Heracleides 
In 1895, a 16th-century book manuscript containing a copy of a text written by Nestorius was discovered by American missionaries in the library of the Nestorian patriarch in the mountains at Konak, Hakkari. This book had suffered damage during Muslim raids, but was substantially intact, and copies were taken secretly. The Syriac translation had the title of the Bazaar of Heracleides. The original 16th-century manuscript was destroyed in 1915 during the Turkish massacres of Assyrian Christians.
In the Bazaar, written towards the end of his life, Nestorius denies the heresy for which he was condemned and instead affirms of Christ "the same one is twofold" – an expression that some consider similar to the formulation of the Council of Chalcedon. Nestorius' earlier surviving writings, however, including his letter written in response to Cyril's charges against him, contain material that suggest that at that time he held that Christ had two persons.
