What does the Bible say about Peter being the rock of the church?

While Peter is called a stone in John 1:42, Scripture teaches that the foundation of the church is built on Christ Himself, not on Peter as an individual. In Matthew 16:18, when Jesus speaks of Peter as the rock, He is referring to the confession of faith that Peter made—acknowledging Jesus as the Christ, the Son of the living God. This aligns with Ephesians 2:20, where Christ is described as the chief cornerstone, indicating that all believers are built upon Him as the foundation of their faith. The assertion that Peter alone is the rock undermines the sole sufficiency of Christ and is contrary to the teachings of the New Testament.
