WHAT is the Orthodox Church? The Orthodox Church is a body or community of people, who, 1—correctly believe in divine revelation; and 2—who obey a lawful hierarchy instituted by our Lord Jesus Christ himself, through the holy apostles. In order to belong to the Orthodox Church two principal conditions are required: First—to accurately accept, rightly understand and truthfully confess the divine teaching of faith; and secondly— to acknowledge the lawful hierarchy or priesthood, to receive from it the holy mysteries or sacraments, and generally to follow its precepts in matters concerning salvation.
