The Council of Chalcedon (n/)[1] was a church council held from October 8 to November 1, AD 451, at Chalcedon. The council is numbered as the fourth ecumenical council by the Catholic Church, the Eastern Orthodox Church, and most Protestants. A minority of Christians, subsequently known as Oriental Orthodoxy, do not agree with the council's teachings.

Its most important achievement was to issue the Chalcedonian Definition, stating that Jesus is "perfect both in deity and in humanness; this selfsame one is also actually God and actually man."[2] The council's judgments and definitions regarding the divine marked a significant turning point in the Christological debates.[3]

Chalcedon was a city in Bithynia, on the Asian side of the Bosphorus; today the city is part of the Republic of Turkey and is known as Kadıköy (a district of Istanbul).


The Council of Chalcedon was convened by Emperor Marcian, with the reluctant approval of Pope Leo the Great, to set aside the 449 Second Council of Ephesus which would become known as the "Latrocinium" or "Robber Council".[4] The Council of Chalcedon issued the Chalcedonian Definition, which repudiated the notion of a single nature in Christ, and declared that he has two natures in one person and hypostasis. It also insisted on the completeness of his two natures: Godhead and manhood.[5] The council also issued 27 disciplinary canons governing church administration and authority. In a further decree, later known as canon 28, the bishops declared that the See of Constantinople (New Rome) had the same patriarchal status as the See of Rome.[6]
