The Ethiopian Orthodox Tewahedo Church became the state church of Ethiopia in the 4th century with the appointment of Abune Sellama as bishop. It traces its beginning to the conversion of the Ethiopian eunuch, treasurer to the Candace, Queen of Ethiopia. Acts 8:26-39.
From the 4th century, beginning with Abune Sellama appointed as bishop, the head of the Ethiopian Orthodox Tewahido Church was always appointed by the Coptic Patriarch of Alexandria in Egypt. The bishops who succeeded Abune Sellama were always Egyptian Copts. The Ethiopian Orthodox church was a part of the Coptic Orthodox church, and recognized the patriarchy of the Pope and Patriarch in Alexandria until 1959,when the Coptic Pope made the church an autocephalous church with its own patriarch.
Ark of the Covenant
The Church claims to have the original ark of the covenant in Aksum at the Church of St. Mary of Zion. Not even the high priest of Aksum can enter its resting chamber. Its sole custodian is a virgin monk who cannot leave the sacred grounds until his death.
Ethiopian Church Calendar
The chronology of the Ethiopian church follows the Era of Incarnation that is it dates from our Lord's birth; there is a difference of 7 or 8 years between the western and Ethiopian systems. Because the Ethiopian church holds that our Lord was born 5500 years after the creation of the world this gives the 7 or 8 years difference between the Gregorian and Ethiopian Chronologies. Bible scholars believe King Herod died in 4 BC which means Christ's birth occurred between 6 BC and 4 BC. This means the Ethiopian Calendar is probably closer to the correct year of Jesus's birth than the Gregorian Calendar in use in most of the world.
The canon of the Ethiopic Bible of the Orthodox Ethiopian Church as a whole differs both in the Old and New Testament from that of any other churches. The books written in the Geez language and on parchment are numerous. The Ethiopic Bible contains 46 books in the Old Testament and 35 books in the New Testament, making a biblical canon of 81 books. Including the books of Jublee and Enoch which are rarely included in other canons.
