The CRC reads Matthew 16:18 as Jesus' affirmation of Peter's faith-confession, not as elevation of Peter to papal authority. In reformed ecclesiology, Christ alone is the foundation and head of the Church; Peter represents the apostolic office and faithful witness. The 'rock' points to the confession 'You are the Christ' as the bedrock of the Church's existence. This interpretation rejects Catholic primacy claims while honoring apostolic authority. Reformed theology emphasizes the Church as a covenant community of believers, not a hierarchical institution centered on one person.
