First Council of Dvin

The First Council of Dvin was a church council held in 506 in the city of Dvin (then in Sasanian Armenia). It convened to discuss the Henotikon, a christological document issued by Byzantine emperor Zeno in an attempt to resolve theological disputes that had arisen from the Council of Chalcedon.

The Armenian Church had not accepted the conclusions of the Council of Chalcedon (fourth Ecumenical Council), which had defined that Christ is 'acknowledged in two natures', and condemned the exclusive use of the formula "from two natures". The latter insisted on the unification of human and divine natures into one composite nature of Christ, and rejected any severing of the natures in reality after the union. This formula was professed by Saints Cyril of Alexandria and Dioscorus of Alexandria. Miaphysitism was the doctrine of the Armenian Church among others. The Henotikon, Emperor Zeno's attempt at conciliation, was published in 482. It reminded bishops of the condemnation of Nestorian doctrine, which emphasized the human nature of Christ, and did not mention the Chalcedonian dyophysite creed.
