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 Orthodox belief in the one single unique 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 and Eastern Orthodox churches.
