 It is considered by many that the Chalcedonian Schism resulted from a difference in semantics rather than actual doctrine, stating that both non-Chalcedonian and Chalcedonian Christianity share a similar Christology despite choosing to express it in different (Cyrillian vs. Chalcedonian) terms, and theological dialogue has resulted in formal statements of agreement on that issue, which have been officially accepted by groups on both sides.The Orthodoxy Cognate PAGE Society (Society for Orthodox Christian Unity and Faith), which is headquartered in India declares the Society's firm belief that, although "the two groups are not in communion with each other", "both the Byzantine (Eastern) Orthodox Churches and the Oriental Orthodox Churches are the true heirs to the One, Holy, Catholic and Apostolic Church of Christ, which was the Church of the apostles and the holy fathers.We also believe these Churches teach the true faith and morals of the Church established by Christ for which the ancient martyrs gave their lives."
