The Chalcedonian Definition is a declaration of Christ's nature, adopted at the Council of Chalcedon in AD 451. Chalcedon was an early centre of Christianity located in Asia Minor. The council was the fourth of the ecumenical councils that are accepted by Chalcedonian churches which include the Catholic, Eastern Orthodox, Lutheran, Anglican and Reformed churches.
The Council of Chalcedon was the fourth ecumenical council of the Christian Church. It was convoked by the Roman emperor Marcian. The council convened in the city of Chalcedon, Bithynia from 8 October to 1 November 451 AD. The council was attended by over 520 bishops or their representatives, making it the largest and best-documented of the first seven ecumenical councils. The principal purpose of the council was to re-assert the teachings of the ecumenical Council of Ephesus against the teachings of Eutyches and Nestorius. Such doctrines viewed Christ's divine and human natures as separate (Nestorianism) or viewed Christ as solely divine (Monophysitism).
Nestorianism is a term used in Christian theology and Church history to refer to several mutually related but doctrinarily distinct sets of teachings. The first meaning of the term is related to the original teachings of Christian theologian Nestorius, 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. The Oxford English Dictionary defines Nestorianism as "The doctrine of Nestorius, patriarch of Constantinople, by which Christ is asserted to have had distinct human and divine persons."
The Second Council of Constantinople is the fifth of the first seven ecumenical councils recognized by both the Eastern Orthodox Church and the Catholic Church. It is also recognized by the Old Catholics and others. Protestant opinions and recognition of it are varied. Some Protestants, such as Calvinists, recognize the first four councils, whereas Lutherans and most Anglo-Catholics accept all seven. Constantinople II was convoked by the Byzantine Emperor Justinian I under the presidency of Patriarch Eutychius of Constantinople. It was held from 5 May to 2 June 553. Participants were overwhelmingly Eastern bishops—only sixteen Western bishops were present, including nine from Illyricum and seven from Africa, but none from Italy—out of the 152 total.
Monophysitism or monophysism is a Christology that states that in the person of the incarnated Word there was only one nature—the divine.
Monothelitism, or monotheletism, is a theological doctrine in Christianity, that holds Christ as having only one will. The doctrine is thus contrary to dyothelitism, a Christological doctrine that holds Christ as having two wills. Historically, monothelitism was closely related to monoenergism, a theological doctrine that holds Jesus Christ as having only one energy. Both doctrines were at the center of Christological disputes during the 7th century.
Chalcedonian Christianity is a term referring to the branches of Christianity that accept and uphold theological resolutions of the Council of Chalcedon, the fourth ecumenical council, held in 451. Chalcedonian Christianity accepts the Christological Definition of Chalcedon, a Christian doctrine concerning the union of two natures in one hypostasis of Jesus Christ, who is thus acknowledged as a single person (prosopon). Chalcedonian Christianity also accepts the Chalcedonian confirmation of the Niceno-Constantinopolitan Creed, thus acknowledging the commitment of Chalcedonism to Nicene Christianity.
Eutyches or Eutyches of Constantinople was a presbyter and archimandrite at Constantinople. He first came to notice in 431 at the First Council of Ephesus, for his vehement opposition to the teachings of Nestorius. At the 448 Synod of Constantinople and the 451 Council of Chalcedon, Eutyches was condemned for having adopted an equally extreme, although opposite view. He himself, however, would reject this interpretation of his thought.
Flavian, sometimes Flavian I, was Archbishop of Constantinople from 446 to 449. He is venerated as a saint by the Eastern Orthodox Church and the Catholic Church.
Anatolius was a Patriarch of Constantinople. He is regarded as a saint, by both the Orthodox and Roman Catholic Churches.
Acacius served as the Ecumenical Patriarch of Constantinople from 472 to 489. He was practically the first prelate in all of Eastern Orthodoxy, and was renowned for his ambitious participation in the Chalcedonian controversy.
Dioscorus I, also known as Dioscorus the Great, was the pope of Alexandria and patriarch of the See of St. Mark who was deposed by the Council of Chalcedon in 451. He was recognized as patriarch by the Coptic Church until his death. He died in Gangra, Paphlagonia, in September 454. He is venerated as a saint by the Coptic and other Oriental Orthodox Churches.
The Henotikon was a christological document issued by Byzantine emperor Zeno in 482, in an unsuccessful attempt to reconcile the differences between the supporters of the Council of Chalcedon and the council's opponents. It was followed by the Acacian schism.
Maximus II was a 5th-century patriarch of Antioch. After the deposition of Domnus II by the Second Council of Ephesus, 449, Dioscorus persuaded the emperor Theodosius II to fill the vacancy with one of the clergy of Constantinople. Maximus was selected and ordained, in violation of canon law, by Patriarch Anatolius of Constantinople, without the official sanction of the clergy or people of Antioch.
Miaphysitism is the Christological doctrine that holds Jesus, the "Incarnate Word, is fully divine and fully human, in one 'nature' (physis)." It is a position held by the Oriental Orthodox Churches and differs from the Chalcedonian position that Jesus is one "person" in two "natures", a divine nature and a human nature (Dyophysitism).
Non-Chalcedonian Christianity comprises the branches of Christianity that do not accept theological resolutions of the Council of Chalcedon, the Fourth Ecumenical Council, held in 451. Non-Chalcedonian denominations reject the Christological Definition of Chalcedon, for varying reasons. Non-Chalcedonian Christianity thus stands in contrast to Chalcedonian Christianity.
The Second Council of Ephesus was a Christological church synod in 449 convened by Emperor Theodosius II under the presidency of Pope Dioscorus I of Alexandria. It was intended to be an ecumenical council, and it is accepted as such by the miaphysite churches but was rejected by Chalcedonian Christians. It was explicitly repudiated by the next council, the Council of Chalcedon of 451, recognised as the fourth ecumenical council by Chalcedonian Christians, and it was named the Latrocinium by Pope Leo I; the Chalcedonian churches, particularly the Roman Catholic and Eastern Orthodox communions, continue to accept this designation, while the Oriental Orthodox repudiate it.
In the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680–681 and finally, the Second Council of Nicaea in 787. All of the seven councils were convened in what is now the country of Turkey.
Oriental Orthodoxy is the communion of Eastern Christian Churches that recognize only three ecumenical councils—the First Council of Nicaea, the First Council of Constantinople and the Council of Ephesus. They reject the dogmatic definitions of the Council of Chalcedon. Hence, these Churches are also called Old Oriental Churches or Non-Chalcedonian Churches.
The Oriental Orthodox Churches are Eastern Christian churches adhering to Miaphysite Christology, with approximately 60 million members worldwide. The Oriental Orthodox Churches are part of the Nicene Christian tradition, and represent one of its oldest branches.
