Ethiopian Orthodox Tewahedo Church

Oriental Orthodox · c. 330 · Ethiopia; diaspora

Africa's ancient church, under Coptic-appointed metropolitans from Aksum until its 20th-century autocephaly; the Derg-era exile synod (1991–2018) was reconciled at Washington on July 25, 2018 — one of the tree's major modern reconciliation annotations. Between 36 and 51 million adherents in Ethiopia.

Ethiopian Orthodox Tewahedo Church was formed around 330. Ethiopian Orthodox Tewahedo Church continues today. Ethiopian Orthodox Tewahedo Church's institutional line runs back through Coptic Orthodox Church of Alexandria, Oriental Orthodoxy to the post-apostolic church. No body on this tree is the assembly of Acts 2; where a body claims that, the claim appears in the claimed-lineage layer.

Between the post-apostolic church and Ethiopian Orthodox Tewahedo Church stand 1 division along the institutional line, counting separations and disputed forks, not mergers, renewals or national organizations.

Solid lines are separations and unions; dashed lines are renewals that began inside a body; dotted gray lines are national organizations of one communion; a diamond marks a fork event where neither side is drawn as the one that left. Every line runs back to the post-apostolic church; no body descends from the assembly of Acts 2. Dashed gray boxes mark the institutional line after the apostles, shown as departure; no line of descent is drawn from Pentecost. A verdict appears on a box once its section is published.
