Tewahedo, and the Word a Church Is Named For

Tewahedo, the word standing in the formal names of both the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church, begins with this letter. It means being made one, a unity, and it is a doctrinal term. It states the position that the divine and the human in Christ are united in one nature, without separation, confusion or change.

That position is what separated these churches, along with the Coptic, Syriac, Armenian and Malankara churches, from the definition adopted at Chalcedon in 451. The term generally used from outside for the group is miaphysite. The older term monophysite is rejected by the churches themselves as a description of a position they do not hold, and the atlas follows their usage. A church carrying a doctrinal word in its own name is telling anyone who reads the name where it stands.

The word is in Ge'ez rather than in Amharic or Tigrinya because the doctrinal register of these churches is Ge'ez. That is the practical reason a dead language keeps a script alive: the theology is carried in the older vocabulary, and tewahedo does not translate cleanly into the modern languages or into English. The controversy it belongs to is among the longest running in Christian history and is not settled here. The naming is a fact and can be recorded as one.
