A) In verse 18, Jesus declares, "Now I say to you that you are Peter, 'Petros' in Greek, meaning a small rock. In fact, upon this rock, 'Petra' in Greek, referring to several rocks collected together in a rock bed, I will build my church." The foundation of the church is not solely Peter, but all believers united in the confession of Jesus Christ. While Peter played a role, each believer, like a little rock, contributes to the building process.
