The Third Council of Dvin was a church council held in 607 (or 609-610) in the city of Dvin (then in Sasanian Armenia). The schism within the Armenian Church which had erupted as a result of the second Chalcedonian Catholicosate in Armenia (591–610), was mended, and the Council of Chalcedon of 451 was explicitly condemned. Although a rift was established with the Georgian church the Council led to mending of a rift within the Armenian Church itself.
