Hey John…
Could you show me the biblical passage where Jesus said that He built His church on the confession of Simon, renamed Peter? He does not make that declaration in Matthew 16?
As I am sure you know the only reason why the Greek translation uses Petros and Petra is because Peter couldn’t be given a feminine name.
Clearly the Pauline letters refer to Simon as Cephas, which means Rock and not pebble.
The Aramaic name for little rock is Kevna, which Paul would have used in lieu of Cephas, which means massive Rock. The Greek word for pebble or small stone is lithos, which surely would have been used in lieu of petros, if Jesus planned to rename Simon a pebble or small rock.
