Within the Orthodox doctrinal teaching on the economy of salvation, Mary's identity, role, and status as "Theotokos" is acknowledged as indispensable. For this reason, it is formally defined as official dogma. The only other Mariological teaching so defined is that of her virginity. Both of these teachings have a bearing on the identity of Jesus Christ. By contrast, certain other Marian beliefs which do not bear directly on the doctrine concerning the person of Jesus (for example, her sinlessness, the circumstances surrounding her conception and birth, her Presentation in the Temple, her continuing virginity following the birth of Jesus, and her death), which are taught and believed by the Orthodox Church (being expressed in the Church's liturgy and patristic writings), are not formally defined by the Church.
