'''Nestorianism''' is a term used in [[Christian theology]] and [[Church history]] to refer to several mutually related but [[doctrinary|doctrinarily]] distinct sets of teachings.{{sfn|Brock|2006|p=177}} The first meaning of the term is related to the original teachings of Christian theologian [[Nestorius]] ({{died in|{{circa|AD 450}}}}), who promoted specific doctrines in the fields of [[Christology]] and [[Mariology]]. The second meaning of the term is much wider, and relates to a set of later theological teachings, that were traditionally labeled as Nestorian, but differ from the teachings of Nestorius in origin, scope and terminology.{{sfn|Baum|Winkler|2003|p=4}} The ''[[Oxford English Dictionary]]'' defines Nestorianism as:<blockquote>"The doctrine of Nestorius, [[Patriarch of Constantinople]] (appointed in 428), by which Christ is asserted to have had distinct human and divine persons."<ref>{{cite encyclopedia |url=https://www.oed.com/view/Entry/126276 |title=Nestorianism |encyclopedia=Oxford English Dictionary}}</ref></blockquote>Original Nestorianism is attested primarily by works of Nestorius, and also by other theological and historical sources that are related to his teachings in the fields of [[Mariology]] and [[Christology]]. His theology was influenced by teachings of [[Theodore of Mopsuestia]] ({{died in|428}}), the most prominent theologian of the [[Catechetical School of Antioch|Antiochian School]]. Nestorian Mariology rejects the title ''[[Theotokos]]'' ('God-bearer') for [[Mary, mother of Jesus|Mary]], thus emphasizing distinction between divine and human aspects of the [[Incarnation (Christianity)|Incarnation]]. Nestorian Christology promotes the concept of a [[prosopic union]] of two persons (divine and human) in [[Jesus|Jesus Christ]],{{sfn|Chesnut|1978|p=392–409}} thus trying to avoid and replace the concept of a [[hypostatic union]]. This Christological position is defined as ''radical dyophysitism'',{{sfn|Burgess|1989|p=90, 229, 231}} and differs from orthodox [[dyophysitism]], that was reaffirmed at the [[Council of Chalcedon]] (451).{{sfn|Meyendorff|1989|p=}} Such teachings brought Nestorius into conflict with other prominent church leaders, most notably [[Cyril of Alexandria]], who issued 12 [[anathema]]s against him (430). Nestorius and his teachings were eventually condemned as [[heresy|heretical]] at the [[Council of Ephesus (431)|Council of Ephesus]] in 431, and again at the [[Council of Chalcedon]] in 451. His teachings were considered as heretical not only in [[Chalcedonian Christianity]], but even more in [[Oriental Orthodoxy]].{{sfn|Meyendorff|1989|p=}}

After the condemnation, some supporters of Nestorius, who were followers of the [[Catechetical School of Antioch|Antiochian School]] and the [[School of Edessa]], relocated to the [[Sasanian Empire]], where they were affiliated with the local Christian community, known as the [[Church of the East]]. During the period from 484 to 612, gradual development led to the creation of specific doctrinal views within the Church of the East.{{sfn|Brock|1999|p=281–298}} Evolution of those views was finalized by prominent [[East Syriac Rite|East Syriac]] theologian [[Babai the Great]] ({{died in|628}}) who was using the specific [[Syriac Christianity|Syriac]] term {{transliteration|syc|qnoma}} ({{lang|syc|ܩܢܘܡܐ}}) as a designation for dual (divine and human) substances within one [[prosopon]] (person or hypostasis) of Christ. Such views were officially adopted by the Church of the East at a council held in 612.{{sfn|Brock|2006|p=}} Opponents of such views labeled them as "Nestorian" thus creating the practice of misnaming the [[Church of the East]] as Nestorian.{{sfn|Baum|Winkler|2003|p=3–5}} For a long time, such labeling seemed appropriate, since Nestorius is officially venerated as a [[Christian saint|saint]] in the [[Church of the East]].{{sfn|Baum|Winkler|2003|p=4–5}} In modern [[religious studies]], this label has been criticized as improper and misleading.{{sfn|Brock|1996|p=23–35}} As a consequence, the use of Nestorian [[label]] in scholarly literature, and also in the field of [[inter-denominational]] relations, is gradually being reduced to its primary meaning, focused on the original teachings of Nestorius.{{sfn|Seleznyov|2010|p=165–190}}

Nestorianism was condemned as [[heresy]] at the [[Council of Ephesus (431)|Council of Ephesus]] (431). The [[Armenian Apostolic Church|Armenian Church]] rejected the [[Council of Chalcedon]] (451) because they believed [[Chalcedonian Definition]] was too similar to Nestorianism. The [[Church of the East|Persian Nestorian Church]], on the other hand, supported the spread of Nestorianism in [[Persarmenia]]. The Armenian Church and other eastern churches saw the rise of Nestorianism as a threat to the independence of their Church. [[Peter the Iberian]], a [[Georgian people|Georgian]] prince, also strongly opposed the Chalcedonian Creed.<ref name=stopka>{{Cite book |publisher=Wydawnictwo UJ |isbn=978-83-233-9555-3 |last=Stopka |first=Krzysztof |title=Armenia Christiana: Armenian Religious Identity and the Churches of Constantinople and Rome (4th–15th Century) |date=2016-12-16 |url=https://books.google.com/books?id=eeq-DQAAQBAJ&pg=PA64 |pages=62–68 |via=[[Google Books]]}}</ref> Thus, in 491, Catholicos Babken I of Armenia, along with the [[Caucasian Albania|Albanian]] and [[Kingdom of Iberia (antiquity)|Iberian]] bishops met in [[Mother See of Holy Etchmiadzin|Vagharshapat]] and issued a condemnation of the Chalcedonian Definition.<ref>{{cite magazine |title=Zvartnots and the Origins of Christian Architecture in Armenia |first=W. Eugene |last=Kleinbauer |magazine=The Art Bulletin |volume=54 |number=3 |date=September 1972 |page=261}}</ref>

Nestorians held that the Council of Chalcedon proved the [[orthodoxy]] of their faith and had started persecuting non-Chalcedonian or [[Miaphysite]] Syriac Christians during the reign of [[Peroz I]]. In response to pleas for assistance from the [[Syriac Orthodox Church|Syriac Church]], Armenian [[prelate]]s issued a letter addressed to Persian Christians reaffirming their condemnation of the Nestorianism as heresy.<ref name=stopka />

Following the exodus to [[Persia]], scholars expanded on the teachings of Nestorius and his mentors, particularly after the relocation of the [[School of Edessa]] to the (then) Persian city of Nisibis (modern-day [[Nusaybin]] in [[Turkey]]) in 489, where it became known as the [[School of Nisibis]].{{citation needed|date=November 2018}} Nestorian monasteries propagating the teachings of the Nisibis school flourished in 6th century Persarmenia.<ref name=stopka />

Despite this initial Eastern expansion, the Nestorians' missionary success was eventually deterred. [[David J. Bosch]] observes, "By the end of the fourteenth century, however, the Nestorian and other churches—which at one time had dotted the landscape of all of Central and even parts of East Asia—were all but wiped out. Isolated pockets of Christianity survived only in India. The religious victors on the vast Central Asian mission field of the Nestorians were [[Islam]] and [[Buddhism]]".<ref>{{cite book |last=Bosch |first=David |author-link=David Bosch |title=Transforming Mission: Paradigm Shifts in Theology of Mission |url=https://books.google.com/books?id=qEpf6wqHcGwC |year=1991 |publisher=[[Orbis Books]] |isbn=978-1-60833-146-8 |page=204 |via=[[Google Books]]}}</ref>

Nestorianism is a radical form of [[dyophysitism]],{{sfn|Burgess|1989|p=90, 229, 231}} differing from orthodox dyophysitism on several points, mainly by opposition to the concept of [[hypostatic union]]. It can be seen as the antithesis to [[monophysitism|Eutychian Monophysitism]], which emerged in reaction to Nestorianism. Where Nestorianism holds that Christ had two loosely united natures, divine and human, Monophysitism holds that he had but a single nature, his human nature being absorbed into his divinity. A brief definition of Nestorian [[Christology]] can be given as: "[[Jesus]] Christ, who is not identical with the Son but personally united with the Son, who lives in him, is one [[hypostasis (philosophy and religion)|hypostasis]] and one nature: human."<ref>Martin Lembke, lecture in the course "Meetings with the World's Religions", Centre for Theology and Religious Studies, [[Lund University]], Spring Term 2010.</ref> This contrasts with Nestorius' own teaching that the Word, which is eternal, and the Flesh, which is not, came together in a hypostatic union, 'Jesus Christ', Jesus thus being both fully man and God, of two ''[[ousia]]'' ({{lang-grc|[[:wikt:οὐσία|οὐσία]]}}) (essences) but of one {{transliteration|grc|[[prosopon]]}} (person).{{sfn|Hodgson|Driver|1925|p=}} Both Nestorianism and Monophysitism were condemned as heretical at the [[Council of Chalcedon]].

[[Nestorius]] developed his Christological views as an attempt to understand and explain rationally the incarnation of the divine [[Logos (Christianity)|Logos]], the Second Person of the Holy Trinity as the man Jesus. He had studied at the [[School of Antioch]] where his mentor had been [[Theodore of Mopsuestia]]; Theodore and other Antioch theologians had long taught a [[Biblical literalism|literalist interpretation of the Bible]] and stressed the distinctiveness of the human and divine natures of Jesus. Nestorius took his Antiochene leanings with him when he was appointed [[Patriarch of Constantinople]] by [[Byzantine Empire|Byzantine]] emperor [[Theodosius II]] in 428.

Nestorius's teachings became the root of controversy when he publicly challenged the long-used title ''Theotokos''<ref name=":1">{{cite journal |first=Eirini |last=Artemi |title=Cyril of Alexandria's critique of the term ''Theotokos'' by Nestorius Constantinople |journal=[[Acta Theologica]] |volume=32 |issue=2 |pages=1–16 |date=December 2012|doi=10.4314/actat.v32i2.1|url=https://www.ajol.info/index.php/actat/article/viewFile/86003/75832 |access-date=2019-10-22 |doi-access=free}}</ref> ('God-Bearer') for Mary. He suggested that the title denied Christ's full humanity, arguing instead that Jesus had two persons (dyoprosopism),{{cn|date=April 2024}} the divine Logos and the human Jesus. As a result of this prosopic duality, he proposed {{transliteration|grc|[[Christotokos]]}} ('[[Christ]]-Bearer') as a more suitable title for Mary.<ref>{{Cite book |last=Palmer-Anghel |first=Martin |title=Kuan Yin: Myths and Prophecies of the Chinese Goddess of Compassion |last2=Ramsay |first2=Jay |last3=Kwok |first3=Man-ho |date=1995 |publisher=[[Thorsons]] |isbn=978-1-85538-417-0 |location=London |pages=22}}</ref>

Nestorius' opponents found his teaching too close to the heresy of [[adoptionism]] – the idea that Christ had been born a man who had later been "adopted" as God's son. Nestorius was especially criticized by [[Cyril of Alexandria|Cyril]], [[Patriarch of Alexandria]], who argued that Nestorius's teachings undermined the unity of Christ's divine and human natures at the [[Incarnation (Christianity)|Incarnation]]. Some of Nestorius's opponents argued that he put too much emphasis on the human nature of Christ, and others debated that the difference that Nestorius implied between the human nature and the divine nature created a fracture in the singularity of Christ, thus creating two Christ figures.<ref>{{cite book |first=Jerry |last=Bentley |title=Old World Encounters: Cross-Cultural Contacts and Exchanges in Pre-Modern Times |url=https://archive.org/details/oldworldencounte00jerr |url-access=registration |location=New York |publisher=[[Oxford University Press]] |date=1993 |page=[https://archive.org/details/oldworldencounte00jerr/page/105 105]}}</ref> Nestorius himself always insisted that his views were orthodox, though they were deemed [[heresy|heretical]] at the [[Council of Ephesus]] in 431, leading to the [[Nestorian Schism]], when churches supportive of Nestorius and the rest of the Christian Church separated. However, this formulation was never adopted by all churches termed 'Nestorian'. Indeed, the modern Assyrian Church of the East, which reveres Nestorius, does not fully subscribe to Nestorian doctrine, though it does not employ the title ''Theotokos''.<ref name=BritannicaNestorius>{{cite encyclopedia |url=https://www.britannica.com/EBchecked/topic/409867/Nestorius |title=Nestorius |encyclopedia=[[Encyclopædia Britannica]] |access-date=January 29, 2010}}</ref>

== Nestorian Schism ==
{{Main|Nestorian Schism}}
Nestorianism became a distinct sect following the [[Nestorian Schism]], beginning in the 430s. Nestorius had come under fire from Western theologians, most notably [[Cyril of Alexandria]]. Cyril had both theological and political reasons for attacking Nestorius; on top of feeling that Nestorianism was an error against true belief, he also wanted to denigrate the head of a competing patriarchate.{{citation needed|date=August 2014}} Cyril and Nestorius asked [[Pope Celestine I]] to weigh in on the matter. Celestine found that the title ''[[Theotokos]]''<ref name=":1"/> was orthodox, and authorized Cyril to ask Nestorius to recant. Cyril, however, used the opportunity to further attack Nestorius, who pleaded with Emperor Theodosius II to call a council so that all grievances could be aired.<ref name=BritannicaNestorius/>

In 431 Theodosius called the Council of Ephesus. However, the council ultimately sided with Cyril, who held that the Christ contained two natures in one divine person (''hypostasis'', unity of subsistence), and that the Virgin Mary, conceiving and bearing this divine person, is truly called the Mother of God (''Theotokos''). The council accused Nestorius of [[heresy]], and deposed him as patriarch.<ref>{{cite web |url=http://www.monachos.net/patristics/christology/cyril_to_nestorius_3.shtml |archive-url=https://web.archive.org/web/20080704053517/http://www.monachos.net/patristics/christology/cyril_to_nestorius_3.shtml |archive-date=July 4, 2008 |title=Cyril of Alexandria, Third Epistle to Nestorius, with 'Twelve Anathemas'|website=Monachos.net}}</ref> Upon returning to his monastery in 436, he was banished to Upper Egypt. Nestorianism was officially anathematized, a ruling reiterated at the [[Council of Chalcedon]] in 451. However, a number of churches, particularly those associated with the [[School of Edessa]], supported Nestorius – though not necessarily his doctrine – and broke with the churches of the West. Many of Nestorius' supporters relocated to the [[Sasanian Empire]] of Iran, home to a vibrant but persecuted Christian minority.<ref name=Britannica>[https://www.britannica.com/topic/Nestorianism "Nestorianism"].

The western provinces of the [[Sasanian Empire|Persian Empire]] had been home to Christian communities, headed by metropolitans, and later patriarchs of [[Seleucia-Ctesiphon]]. The Christian minority in Persia was frequently persecuted by the [[Zoroastrianism|Zoroastrian]] majority, which accused local Christians of political leanings towards the [[Roman Empire]]. In 424, the Church in Persia declared itself independent, in order to ward off allegations of any foreign allegiance. By the end of the 5th century, the Persian Church increasingly aligned itself with the teachings of [[Theodore of Mopsuestia]] and his followers, many of whom became dissidents after the Councils of [[Council of Ephesus (431)|Ephesus]] (431) and [[Council of Chalcedon|Chalcedon]] (451). The Persian Church became increasingly opposed to doctrines promoted by those councils, thus furthering the divide between [[Chalcedonian Christianity|Chalcedonian]] and Persian currents.{{sfn|Meyendorff|1989|p=}}

In 486, the Metropolitan [[Barsauma of Nisibis|Barsauma]] of [[Nisibis]] 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 (emperor)|Zeno]] for its pro-Nestorian teachings, the school relocated to its original home of Nisibis, becoming again the [[School of Nisibis]], leading to the migration of a wave of Christian dissidents into Persia. The Persian patriarch [[Babai (Nestorian patriarch)|Babai]] (497–502) reiterated and expanded upon the church's esteem for [[Theodore of Mopsuestia]].

Now firmly established in Persia, with centers in Nisibis, [[Ctesiphon]], and [[Gundeshapur]], and several [[Metropolis (religious jurisdiction)|''metropoleis'']], the Persian Church began to branch out beyond the Sasanian Empire. However, through the sixth century, the church was frequently beset with internal strife and persecution by Zoroastrians. The infighting led to a schism, which lasted from 521 until around 539 when the issues were resolved. However, immediately afterward Roman-Persian conflict led to the persecution of the church by the Sassanid emperor [[Khosrow I]]; this ended in 545. The church survived these trials under the guidance of Patriarch [[Aba I]], who had converted to Christianity from Zoroastrianism.<ref name=Britannica/>

The church emerged stronger after this period of ordeal, and increased missionary efforts farther afield. Missionaries established dioceses in the [[Arabian Peninsula]] and [[India]] (the [[Saint Thomas Christians]]). They made some advances in [[Egypt]], despite the strong [[Miaphysitism|Miaphysite]] presence there.<ref>{{cite book |last=Campbell |first=Ted |title=Christian Confessions: A Historical Introduction |url=https://books.google.com/books?id=p2mUxxxGt_sC&pg=PA62 |year=1996 |location=Westminster |publisher=[[John Knox Press]] |isbn=978-0-664-25650-0 |page=62 |via=[[Google Books]]}}</ref> Missionaries entered [[Central Asia]] and had significant success converting local [[Turkic peoples|Turkic]] tribes.

Nestorian missionaries were firmly established in China during the early part of the [[Tang dynasty]] (618–907); the Chinese source known as the [[Nestorian Stele]] records a mission under a Persian proselyte named [[Alopen]] as introducing Nestorian Christianity to China in 635. The [[Jingjiao Documents]] (also described by the Japanese scholar P. Y. Saeki as "Nestorian Documents") or [[Jesus Sutras]] are said to be connected with Alopen.<ref>{{cite book |last1=Riegert |first1=Ray |title=The Lost Sutras of Jesus: Unlocking the Ancient Wisdom of the Xian Monks |date=January 26, 2006 |publisher=Ulysses Press |isbn=1-56975-522-1 |pages=9–23 |url=https://books.google.com/books?id=rDuNAAAAMAAJ&q=the+lost+sutras+of+jesus |via=[[Google Books]]}}</ref>

Following the [[Muslim conquest of Persia|Arab conquest of Persia]], completed in 644, the Persian Church became a {{transliteration|ar|[[dhimmi]]}} community under the [[Rashidun Caliphate]]. The church and its communities abroad grew larger under the caliphate. By the 10th century it had 15 metropolitan sees within the caliphate's territories, and another five elsewhere, including in China and India.<ref name=Britannica/> After that time, however, Nestorianism went into decline.{{Disputed inline|date=October 2019}}
