ልሳነ ተዋሕዶ ዘኦርቶዶክስ Lesane Tewahdo ZeOrthodox

Tewahedo (Ge'ez ተዋሕዶ täwaḥədo) is a Ge'ez word meaning "being made one" or "unified". This word refers to the Oriental Orthodox belief in the one single unified 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, but unseparated Divine and Human Natures, called the Hypostatic Union) which is held by the Roman Catholic and Eastern Orthodox Churches. According to the Catholic Encyclopedia article on the Henotikon,[1] around 500 bishops within the Patriarchates of Alexandria, Antioch and Jerusalem refused to accept the "two natures" doctrine decreed by the Council of Chalcedon in 451, thus separating themselves from the main body of the Christian Church at the time, which would later itself split in two factions (Eastern Orthodox and Roman Catholic) in the East-West Schism of 1054, although this later event was not about Christological views.

The Oriental Orthodox Churches, which today include the Coptic Orthodox Church of Alexandria, the Armenian Apostolic Church, the Syriac Orthodox Church, the Malankara Orthodox Church of India, the Ethiopian Orthodox Tewahedo Church, and the Eritrean Orthodox Tewahedo Church, are referred to as "Non-Chalcedonian", and, sometimes by outsiders as "monophysite" (meaning "One Single Nature", in reference to Christ). However, these Churches themselves describe their Christology as miaphysite (meaning "One United Nature", in reference to Christ; the translation of the word "Tewahedo")
