Nonsense.
Jesus was referring not to Peter, but to Himself in Matthew 16. This is borne out by the fact that He reprimanded Peter just a few verses later with, “Get thee behind me, Satan.”
There are several passages elsewhere which confirm that Jesus is the Rock.
1 Corinthians 3:11, Paul speaking: “For no other foundation can anyone lay, than that which is laid, which is Jesus Christ.”
Psalm 118:8: “It is better to trust in the Lord than to put confidence in man.”
Psalm 18:2, David speaking: “The Lord is my Rock...”
Psalm 18:31: “And who is a Rock, except our God?”
In Ephesians 2, Paul says Jesus is tne “chief cornerstone.”
Even Peter himself confirms it. In 1 Peter 1 4-6, he says that we all (including him) are stones in the building of the church, while Jesus is the cornerstone. “Coming to Him as to a living stone, rejected indeed by men, but chosen by God and precious, you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. Therefore it is also contained in the Scripture, Behold, I lay in Zion A chief cornerstone, elect, precious, And he who believes on Him will by no means be put to shame.”
In view of all these Scriptures, I place my trust in the one true Rock, the one Truth, who is Jesus Christ; as such, He is my salvation, and I am blessed indeed.
Except when Christ said this in Aramaic Peter’s name Kepha is equated with the word for rock, kepha.
