Calvary Chapel's expository reading of Matthew 16:18 emphasizes the wordplay: Peter (Petros) and rock (petra). Jesus gives Peter special authority—'keys of the kingdom'—for pastoral leadership and teaching. This is understood as real authority for Peter and the apostles, though not the papal supremacy claimed by Catholic theology.

Chuck Smith's approach takes the text straightforwardly: Jesus builds his church through Peter's role as a leading apostle. The 'keys' represent authority to teach, bind, and loose (Matthew 18:18)—pastoral decisions made by church leaders. The passage establishes apostolic authority without requiring complex theological frameworks about church structures.
