Memnon was metropolitan bishop of Ephesus during the third ecumenical council. [1]
At the Council he was a supporter of Cyril of Alexandria. Delays in the opening of the Council were blamed by Nestorius on Memnon. [2]
Memnon hosted the second session of the Council in his episcopal palace and at the fourth session Cyril and Memnon presented a formal protest against John of Antioch for convening a separate conciliabulum, which condemned both of them. [3]
Reportedly out of jealousy, Memnon sought to get rid of Bassianus, a priest under him, by ordaining him to the bishopric of Evaza. Bassianus refused the position and in 444 became, by an irregular process, Memnon's second successor. [4]
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 heresies of Eutyches and Nestorius. Such heresies attempted to dismantle and separate Christ's divine nature from his humanity (Nestorianism) and further, to limit Christ as solely divine in nature (Monophysitism).
Cyril of Alexandria was the Patriarch of Alexandria from 412 to 444. He was enthroned when the city was at the height of its influence and power within the Roman Empire. Cyril wrote extensively and was a major player in the Christological controversies of the late-4th and 5th centuries. He was a central figure in the Council of Ephesus in 431, which led to the deposition of Nestorius as Patriarch of Constantinople. Cyril is counted among the Church Fathers and also as a Doctor of the Church, and his reputation within the Christian world has resulted in his titles Pillar of Faith and Seal of all the Fathers. The Nestorian bishops at their synod at the Council of Ephesus declared him a heretic, labelling him as a "monster, born and educated for the destruction of the church."
An ecumenical council, also called general council, is a meeting of bishops and other church authorities to consider and rule on questions of Christian doctrine, administration, discipline, and other matters in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church.
The Council of Ephesus was a council of Christian bishops convened in Ephesus in AD 431 by the Roman Emperor Theodosius II. This third ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, confirmed the original Nicene Creed, and condemned the teachings of Nestorius, Patriarch of Constantinople, who held that the Virgin Mary may be called the Christotokos, "Christ-bearer" but not the Theotokos, "God-bearer". It met in June and July 431 at the Church of Mary in Ephesus in Anatolia.
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.
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.
Nestorius was the Archbishop of Constantinople from 10 April 428 to August 431. A Christian theologian, several of his teachings in the fields of Christology and Mariology were seen as controversial and caused major disputes. He was condemned and deposed from his see by the Council of Ephesus, the third Ecumenical Council, in 431.
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; his condemnation of Nestorianism as heresy led him to an equally extreme, although opposite view, which precipitated his being denounced as a heretic himself.
Anatolius was a Patriarch of Constantinople. He is regarded as a saint, by both the Orthodox and Roman Catholic Churches.
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.
Miaphysitism = Unique Nature 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).
The Second Council of Ephesus was a Christological church synod in 449 AD 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 the Chalcedonian dyophysites. 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 or "Robber Council" 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.
Saint Juvenal was a bishop of Jerusalem from about 422. In 451, on the See of Jerusalem being recognised as a Patriarchate by the Council of Chalcedon, he became the first Patriarch of Jerusalem, an office he occupied until his death in 458.
In Christian theology, dyophysitism is the Christological position that two natures, divine and human, co-exist in the unique person of Jesus Christ God.
Coptic history is the part of the history of Egypt that begins with the introduction of Christianity in Egypt in the 1st century AD during the Roman period, and covers the history of the Copts to the present day. Many of the historic items related to Coptic Christianity are on display in many museums around the world and a large number is in the Coptic Museum in Coptic Cairo.
Bassianus was the Bishop of Ephesus (444–448).
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.
In the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God. The Council rejected Nestorius' view causing many churches, centered on the School of Edessa, to a Nestorian break with the imperial church. Persecuted within the Roman Empire, many Nestorians fled to Persia and joined the Sassanid Church thereby making it a center of Nestorianism. By the end of the 5th century, the global Christian population was estimated at 10-11 million. In 451 the Council of Chalcedon was held to clarify the issue further. The council ultimately stated that Christ's divine and human nature were separate but both part of a single entity, a viewpoint rejected by many churches who called themselves miaphysites. The resulting schism created a communion of churches, including the Armenian, Syrian, and Egyptian churches, that is today known as Oriental Orthodoxy. In spite of these schisms, however, the imperial church still came to represent the majority of Christians within the Roman Empire.
The Metropolis of Ephesus was an ecclesiastical territory (metropolis) of the Ecumenical Patriarchate of Constantinople in western Asia Minor, modern Turkey. Christianity was introduced already in the city of Ephesus in the 1st century AD by Paul the Apostle. The local Christian community comprised one of the seven churches of Asia mentioned at the Book of Revelation, written by John the Apostle. The metropolis remained active until 1922-1923.
