Relations With Other Christians
Orthodoxy represents the majority of Eastern Christianity. The Orthodox trace their bishops back to the apostles through apostolic succession, venerate saints, especially Mary the Mother of God as the Theotokos, pray for the dead, and continue the ancient Christian practice of monasticism. Orthodoxy does not openly promote statuary, although it is not expressly condemned, instead limiting itself primarily to two-dimensional iconography. The Western theological concepts of original sin, predestination, purgatory and particular judgment are generally rejected by traditional Orthodox theologians.
The Orthodox understand themselves to be the One Holy Catholic and Apostolic Church; the true Church established by Jesus Christ and placed into the care of the apostles. As almost all other Christian groups are in indirect schism with the Orthodox Church, mostly as a result of the Great Schism with the Roman Catholic Church at the turn of the second Christian millennium (prior to the additional schisms of the Protestant Reformation), these other groups are viewed as being Christian, but who in varying degrees lack full theological orthodoxy and orthopraxy. As such, all groups outside of the Orthodox Church are not seen as being members of the Church proper, but rather separated brethren who have failed to retain the fullness of the Christian faith and theology, as was given to the apostles by Jesus Christ. These deviations from orthodoxy have traditionally been called heresy, but due to the term's immediately pejorative connotations, some prefer the more technical designation of the term heterodoxy.
Hilarion Alfeyev, the Metropolitan of Volokolamsk and head of external relations for the Moscow Patriarchate of the Russian Orthodox Church, stated that Orthodox and evangelical Christians share the same positions on "such issues as abortion, the family, and marriage" and desire "vigorous grassroots engagement" between the two Christian communions on such issues.
