[OLD REGGIE]

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.

Oh I see??????????????????????

I am sitting on my desk chair.

I am sitting of my desk chair.

Same thing.

Logic 101.

[small voice in the wilderness]

The Catechism of the Catholic Church states that Peter is the rock upon which Christ would build His church. The official Roman Catholic position. Right?

what does this mean, then?

"Moved by the grace of the Holy Spirit and drawn by the Father, we believe in Jesus and confess: "You are the Christ, the Son of the living God. On the ROCK OF THIS FAITH CONFESSED BY ST. PETER, CHRIST BUILT HIS CHURCH. - Catechism of the Catholic Church.

Doesn't anyone find it curious that this was also stated?

[Deo volente]

Oh come on now, this is getting ridiculous!

Christ built His Church on the rock, which is Peter.

Peter is the rock on which Christ built His Church. Peter is the rock of the Church. It means the same thing.

You sit ON your desk chair. You don't sit on Peter, but Christ built His Church on Peter.
The “desk chair” attempt at linguistic equivalence is just plain silly.

[Cronos]

You do realise you are using the rules of English grammar to try and understand the rules of Aramaic and / or koine Greek grammar, right?

Next you would say that we don't have a grammatically clear explanation for God the FAther, Son and Holy Spirit being a Trinity
