Even after re-naming him Peter Jesus several times calls him Simon. The name Peter aka rock came because of Simons saying Jesus is the Son of GOD. Only Jesus is the true rock as foretold as the cornerstone in the Old Testament. Simon’s name change came about because of what was revealed to him which he professed and Jesus being the rock upon which Jesus will build his church. The new temple is Christ living within man. The temple in Jerusalem was destroyed within a few decades. The Apostles, Disciples, Elders, and believers, would worship Jesus in spirit just as He told the woman at the well. In GOD Given calling to minister, a street preacher is no less of a preacher than a Pope or a Priest in a remote nation any less a preacher than one as an example Billy Graham was. All serve the same Lord.
“Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”
We are all living stones being built up into God's dwelling place.
Peter is not the only one.
