Monophysitism (from the Greek monos meaning 'one' and physis meaning 'nature') is the christological position that Christ has only one nature, as opposed to the Chalcedonian position which holds that Christ has two natures, one divine and one human. There are two major doctrines that can undisputedly be called monophysite: The radical monophysitism of Eutyches emerged in Egypt as a response to Nestorianism. It was rejected at the Council of Chalcedon in 451 and is also rejected by the Oriental Orthodox Churches.
