Peter is NOT the Rock, God the Father is. You are wrong on multiple counts.
"For they drank of that spiritual Rock that followed them, and that Rock was Christ."
Christ is not God the Father.
Also, who was called "Cephas"?
So you are saying that this verse is not the “inspired word of God” or He was mistaken, or what?
Isaiah 44:8, "Is there any God besides Me, or is there any other Rock? I know of none."
