:''This 431 council is distinguished from the "
Second Council of Ephesus" in AD 449''.

Cyril of Alexandria
The 'Council of Ephesus' was held in the
Church of Mary in
Ephesus, Asia Minor in
431 under Emperor
Theodosius II, grandson of
Theodosius the Great; Ephesus was the city of
Artemis (see ). Approximately 200
bishops were present. The proceedings were conducted in a heated atmosphere of confrontation and recriminations. It is counted as the 'Third
Ecumenical Council', and was chiefly concerned with
Nestorianism.
Nestorianism emphasized the dual natures of
Christ. Patriarch
Nestorius taught that
Mary, the mother of Jesus gave birth to the incarnate Christ, not the divine
Logos who existed before Mary and indeed before time itself. Consequently, Mary should be called ''Christotokos'', Greek for the "Christ-Bearer" and not
Theotokos, Greek for the "God-Bearer." This was essentially a
Christological controversy.
At the urging of its president,
Cyril of Alexandria, the Council denounced Nestorius' teaching as erroneous and decreed that Jesus was one person, not two separate people: complete God and complete man, with a rational soul and body.
The Virgin Mary was to be called
Theotokos because she bore and gave birth to
God as a man. This did not resolve the debate over the
union of the two natures of Christ, and related issues were debated at the
Council of Chalcedon.
The Council of Ephesus also declared the text of the
Nicene Creed of 381 to be complete and forbade any
additional change (addition or deletion) to it. In addition, it condemned
Pelagianism.
Eight canons
[1] were passed:
Canon 1 decreed a heretic named Celestius (so Scholion),
anathema.
Canon 2-5 decreed
Nestorianism anathema.
Canon 6 decreed those who do not abide by the canons of Ephesus are
excommunicated.
Canon 7 decreed those who do not abide by
Nicaea are anathema.
Canon 8: "Let the rights of each province be preserved pure and inviolate. No attempt to introduce any form contrary to these shall be of any avail." Mention is made of the
Canons of the Apostles.
