Hi, Again!
I just wanted to add one more thing to my previous posting, which I forgot to mention. With regard to Christ's statement that "You are Peter and on this rock...", which we showed referred not to the person of Peter, but to the confession of faith that he made, another proof of this is the fact that in the Gospel, immediately after that, Christ says to Peter (or more accurately, to the devil who is trying to use Peter), "Get thee behind Me, Satan!"
So if we take all this at face value, at one moment Peter is worthy of having the whole Church founded on him, and in the next he is equated with Satan and told to "get thee behind Me". As can be plainly seen, the answer lies in what was said in previous posts -- not in what the Roman Catholics present as some special role bestowed on Peter as the foundation of the Church.
In Christ,
Damian
