Mark 3:16 – Jesus gave Simon the name Peter or Cephas which means a stone (John 1:42).
Matthew 16:18 – “And I also say to you that you are Peter, and on this Rock I will build My church, and the gates of Hades shall not prevail against it.”
Jesus was saying, “Yes, Peter, You are blessed because My Father revealed to you that I am the Christ, the Son of the living God. I say to you, Peter (a stone) on this Rock (Myself) I will build My church and the gates of Hades (the grave) will not prevail against it.” Like Jesus, His church will have victory over the grave.
Peter had declared who Jesus was in John 6:69. “Also we have come to believe and know that You are the Christ, the Son of the living God.”
In Luke 9:18-21, Jesus asked His disicples, “Who do the crowds say that I am?” So, they answered and said, “John the Baptist, but some say Elijah; and others say that one of the old prophets has risen again.” He said to them, “But who do you say that I am?” Peter answered and said, “The Christ of God.” And He strictly warned and commanded them not to tell this to anyone.
Peter’s name was not changed from stone to rock. Jesus did not build His church on Peter who had spoken up and said who Jesus was . Jesus built the church on Himself, the Rock, the Christ, the Son of the living God. That is why He is the Head of the church. Peter was one of the stones that built the church like we are the many parts that make up the body of the church. We are members of the body of Christ and He is the Head.
Peter himself said that we as “living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ” (1 Peter 2:5).
Jesus is the chief cornerstone (1 Peter 2:7). Isaiah 28:16 says, “A precious cornerstone, a sure foundation.”
Jesus is a sure foundation. He is a Rock–immovable not like Peter, a stone that is easily dislodged. Jesus is the Foundation of the church and of our faith. 1 Corinthians 10:4 says, “For they drank of that spiritual Rock that followed them, and that Rock was Christ.”
