Monophysitism. The doctrine that in the Incarnate Christ there is only one nature, not two. The term covers a variety of positions, some capable of orthodox interpretation, others not. The term ‘Monophysite’ was first used in the aftermath of the Council of
Chalcedon (451) to describe all those who rejected the Council's Definition that the Incarnate Christ is one Person ‘in two natures’. They did so on the ground that it obscured the full reality of the Incarnation and seemed to them to verge on Nestorianism.
Eutyches taught a heretical form of Monophysitism, namely that after the Incarnation there was only one nature in Christ, and that that nature was not ‘con-substantial with us’. Moderate Monophysites taught that in the Incarnate Christ there was ‘one nature out of two’ (i.e. Divine and human). They were led by
Severus of Antioch. An extreme type of Monophysitism was held by the
Aphthartodocetae (q.v.).
During the 5th and 6th cents. many attempts were made to reconcile the Monophysites to the Catholics, including those by the Emps.
Zeno, *Justinian I, and
Heraclius, but separate hierarchies emerged to constitute the
Armenian, *Coptic, *Ethiopian, and
Syrian Orthodox Churches. In modern times there have been renewed contacts with both the Orthodox Churches and the RC Church, and a measure of agreement on Christology is reflected in recent statements.
