[OLD REGGIE]

You must not have read the entire excerpt you posted from the Catechism. Peter IS the rock upon which Christ built His Church. It's right there in front of you, plain as day.

"Christ, the 'living Stone',[1 Pet 2:4.] thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakable rock of the Church."

Yes, it was because of his unshakable faith that Peter was chosen, but the Lord clearly made him the rock on which the Church was built. Simon's name was changed by Jesus to Peter, which in Aramaic means "rock". "Petros" is the Greek transliteration.

If by your reference to "excerpt" you are correct in that I didn't post the entire Catechism. However, I did post the only two references to "Peter" and "rock". Sheesh, what do you want from me.

Forgive me in advance but I am going to highlight the key words which deny your definition by large colored, and bolded script.

Ready now:

"Christ, the 'living Stone',[1 Pet 2:4.] thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakable rock of the Church."

If you can't distinguish between "on" and "of" I can't help you. (Hint - "Because" is the qualifier")

I have no idea what point you're trying to make. Really.

Peter is the rock on which Christ built His Church; Peter is the “rock of the Church”. Same thing. No difference. Peter is not THE Church, of course, but He is the rock on which the Church was built.

“rock on...”, “rock of...”, same thing.

Be careful! LOL.

They’ll enjoy tarring you with the brush they seem so addicted to using on me! LOL.

I'm pretty much beyond help anyway, but ...

Wait! A rock or Peter ON the Church don't make no sense!
