Through history, how have theologians understood Matthew 16:18–19?

Church & Practice

Researched by the Ignaria editorial team · Updated 2026-07-27

Matthew 16:18–19 is a classic “through history” question: the same words have grounded confession-centered readings, Petrine / papal claims, and shared ecclesial authority. The declared corpus can surface that development and disagreement; where one side is thinner in the library, the brief should stay honest rather than invent balance.
