Is Peter the Rock in Matthew 16:18?
The word for “Peter” in this verse is the Greek word petros which means a pebble. Jesus goes on to say that upon this rock, petra, he would build his church. The Greek word petra means a large rock such as the ridge of a mountain or the ledge of a cliff. In other words, Jesus is saying, “Peter, you are a tiny pebble, but I am going to build my church on a great big mountain ridge.” What is the giant rock that Jesus would build His church upon? It is nothing else but the confession of Peter that Jesus is the Son of God. Christ is the rock!
