1. In its own words
The entity stated in its own words: its self-description, before any external description.
Christianity
Christianity began as a Jewish movement proclaiming Jesus as the Messiah and grew, through the early councils, the great schisms, and the Reformations, into the largest of the world religions. Its internal divisions are not decorations on a single body; they are the substance of its history, and this tree models them as first-class entities, from the ancient branches to the denominations and movements of today.

Confidence: high
Eastern Orthodox
The Eastern Orthodox Church is a communion of autocephalous churches, each governing itself, bound by the faith of the seven ecumenical councils and by eucharistic communion with one another. Its separation from the Oriental Orthodox turns on the Council of Chalcedon, and its separation from Rome on the schism of 1054 and all that followed.

| What this comparison cannot settle | populated: This comparison sets two self-descriptions side by side; it does not decide between them. A tradition is a living range of positions, and each panel renders the range this site has documented, which is not the whole of the tradition. Where a cell is marked not yet documented, the gap belongs to this site's documentation, not to the tradition. Questions of truth between the panels turn on premises the reader brings: what counts as evidence, what authority is recognized, and what a human life is for.
