# Catholic and Oriental Orthodox: a Diptych comparison Schema version 1.0. The Diptych displays; it does not score, rank, or adjudicate. ## 1. In its own words ### Catholic The Catholic Church is the largest single body in Christianity. It understands itself as the continuing church of the apostles, governed by bishops in communion with the Pope, and it carries the Latin Church and the Eastern Catholic Churches within one communion. - [Catholic](/tree/catholic) ### Oriental Orthodox The Oriental Orthodox communion gathers the Coptic, Syriac, Armenian, Ethiopian, Eritrean, and Malankara churches. Their separation from the Chalcedonian churches is the oldest standing division in Christianity, and modern dialogue has established that the ancient quarrel rested in large part on terminology rather than on the faith confessed. - [Oriental Orthodox](/tree/oriental-orthodox) ## 2. Scale and spread ### Catholic The Catholic Church counts about 1.38 billion baptized members, close to half of all Christians, organized in more than 3,000 dioceses. The largest populations stand in Latin America, Europe, and Africa, and the church is the largest single Christian body in the world. - [Catholic](/tree/catholic) ### Oriental Orthodox The Oriental Orthodox communion counts roughly 60 million adherents across its six autocephalous churches. The Ethiopian Orthodox Tewahedo Church is the largest, followed by the Coptic Orthodox Church in Egypt, with the Armenian, Syriac, Eritrean, and Malankara churches beside them. - [Oriental Orthodox](/tree/oriental-orthodox) ## 3.

What this comparison cannot settle ### Catholic 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. The instrument does not score, rank, or adjudicate. ### Oriental Orthodox This comparison sets two self-descriptions side by side; it does not decide between them.
