Wikipedia extract

The Chalcedonian Definition is the declaration of Christ as fully God and fully human, having two natures "without confusion, without change, without division, without separation", 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 and Orthodox churches.
