1. In its own words

The entity stated in its own words: its self-description, before any external description.

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.

Confidence: high

Protestant

Protestant names the family of churches that separated from Rome in the Reformation, or descend from those that did. It is a branch, not a single church: Lutheran, Reformed, Anglican, Baptist, Anabaptist, Methodist, and independent bodies share the Reformation's founding claims while differing on sacraments, ministry, and the church itself.

19. What this comparison cannot settle

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.

Sections this comparison cannot yet speak to, because the documentation is incomplete: Ultimate reality, The human person, Problem and solution, Ethics and hard cases, Community and governance, Contributions, Internal critique, External critique and reply, What each says about the other.

On the questions where these two panels disagree, the outcome turns on premises the reader brings: what counts as evidence, which authority is recognized, and what a human life is for. This instrument settles none of those.
