Ethiopian Orthodox Church at English => English (The Britannica Concise) Of Explained:
Independent Christian patriarchate in Ethiopia. Founded in the 4th cent. by St. Frumentius and his brother Aedesius and based in Addis Ababa, the church adheres to Monophysite doctrine (see Monophysite heresy). It accepts the honorary primacy of the Coptic patriarch of Alexandria, who appointed its archbishops from the 12th cent. until 1959, when an autonomous Ethiopian patriarchate was established. Its customs include circumcision, rigorous fasting, and the participation of laypeople known as debtera, who perform liturgical music and dances and act as astrologers, scribes, and fortune-tellers. Its principal adherents are the Amhara and Tigray peoples of the N and central highlands. See also Coptic Orthodox Church.
