The rock is Peter?

In Matthew 16:18 Jesus did not mean that the rock is Peter. When he said on this rock the rock was He. Christ was the rock that the Israelites drank in the wilderness. (1 Corinthians 10: 4) Is there 2 Rocks? If Peter is the rock, what about the rock that is Jesus? Peter said to Peter in Greek: "You are PETROS," meaning stone. The Greek word for the rock is not PETROS but PETRA. Peter was Jesus himself, and Peter was a Peter. (1 Peter 5: 1) Also, do not forget that the so-called Peter the rock of the Catholics was once imposed by Paul in front of the church (Galatians 2: 11-14). Peter was Good Apostle and witness to the Lord Jesus, but not to the rock. If we say so, we offend the Lord Jesus who is the real rock for the church.
