''Tewahedo'' (Ge'ez ''tawāhidō'', modern pronunciation ''tewāhidō'') is a Ge'ez word meaning "being made one"; it is related to the Arabic word توحيد ''tawhid'', meaning "monotheism," or more literally "unification." This refers to the [[Oriental Orthodoxy|Oriental Orthodox]] belief in the one single unique [[Christology|Nature of Christ]] (i.e., a belief that a complete, natural union of the Divine and Human Natures into One is self-evident in order to accomplish the divine salvation of humankind), as opposed to the "two Natures of Christ" belief (unmixed, separated Divine and Human Natures, called the [[Hypostatic Union]]) promoted by today's [[Roman Catholic Church|Roman Catholic]] and Eastern Orthodox churches. According to the Catholic Encyclopedia article on the [[Henoticon]] [http://www.newadvent.org/cathen/07218b.htm]: the [[Patriarch]]s of Alexandria, Antioch, and Jerusalem, and many others, all refused to accept the "two natures" doctrine decreed by the Byzantine Emperor Marcian's [[Council of Chalcedon]] in 451, thus separating them from the Roman Catholic and Eastern Orthodox, who themselves separated from one another later in the [[Great Schism]] (1054). The Oriental Orthodox Churches, which today include the [[Church of Alexandria (Coptic)|Coptic Orthodox Church]], the [[Church of Armenia|Armenian Apostolic Church]], the [[Church of Antioch (Syriac)|Syriac Orthodox Church]], the [[Church of India|Malankara Orthodox Church]] of India, the Ethiopian Orthodox Church, and the [[Church of Eritrea|Eritrean Orthodox Tewahedo Church]], are referred to as "Non-Chalcedonian", and, sometimes by outsiders as "[[Monophysitism|monophysite]]" (meaning "One Nature", in reference to Christ; a rough translation of the name ''Tewahido''). However, these Churches themselves describe their [[Christology]] as [[
The Church of Ethiopia claims its origins from [[Philip the Evangelist]] ([[Acts of the Apostles|Acts]] 8). It became the established church of the Ethiopian Axumite Kingdom under king Ezana in the 4th century through the efforts of a Syrian Greek named [[Frumentius of Axum|Frumentius]], known in Ethiopia as ''Abba Selama, Kesaté Birhan'' ("Father of Peace, Revealer of Light"). As a boy, Frumentius had been shipwrecked with his brother Aedesius on the Eritrean coast. The brothers managed to be brought to the royal court, where they rose to positions of influence and converted Emperor Ezana to Christianity, causing him to be baptized. Ezana sent Frumentius to Alexandria to ask the Patriarch, St. [[Athanasius the Great|Athanasius]], to appoint a bishop for Ethiopia. Athanasius appointed Frumentius himself, who returned to Ethiopia as Bishop with the name of ''Abune Selama''. For centuries afterward, the Coptic Patriarch of Alexandria always named a Copt (''an Egyptian'') to be ''[[Abuna]]'' or Archbishop of the Ethiopian Church.
