Second Council of Dvin

The Second Council of Dvin was a church Synod or Church Council held in 554 in the city of Dvin (then in Sasanian Armenia). However, despite the convocation, the response from the bishops was inadequate and the

synod failed to materialise. The synod did not meet at Dvin until 21st March, the Palm Sunday of 555, with 18 bishops attending.

The Second Council of Dvin was called by Catholicos Nerses II of Bagrevand, and it was in this council that the bishops declined to accept the canons of Chalcedon. This was significant as it was the moment where the Armenian Church formally rejected the dyophysite formula that had been adopted by some bishops at the Council of Chalcedon. This decision was made because of the Armenians' observation that the decrees of Chalcedon had caused the doctrine of Nestorius to spread.
