Woops - you forgot to read the whole book to get the context. Here is what else the Catechism has to say about St. Peter:
CCC paragraph 881: The Lord made Simon alone, whom he named Peter, the "rock" of his Church. He gave him the keys of his Church and instituted him shepherd of the whole flock. "The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head." This pastoral office of Peter and the other apostles belongs to the Church's very foundation and is continued by the bishops under the primacy of the Pope.
Going back and forth on the exact meaning of the words in Matthew I6 is somewhat like doing the same to certain undefined terms in the Constitution, such as "commander-in-chief" One thing is clear: the writers of the Constitution conferred a title on the President and implicitly, a function, but it is history that has defined the limits of its exercise.
John 21:20 Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? 21 Peter, seeing him, saith to Jesus, Lord, and what shall this man do?
22 Jesus saith unto him, If I will that he tarry till I come, what is that to thee? ... follow thou me.
23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?
24 This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.

Read the entire Catechism? No I haven't. Have you? I did; however, read Paragraph 881. I took the liberty of highlighting the operative word. There is a massive difference between a claim that Peter is the rock
of his Church and the claim that Peter is
the Rock.
1Corinthians 10:
[4] and all drank the same supernatural drink. For they drank from the supernatural Rock which followed them, and the Rock was Christ.
According to Scripture there is only one Rock upon which the Church is built.

Of course one as familiar with the Catechism as you didn't miss the following:
552 Simon Peter holds the first place in the college of the Twelve; (283) Jesus entrusted a unique mission to him. Through a revelation from the Father, Peter had confessed: "You are the Christ, the Son of the living God." Our Lord then declared to him: "You are Peter, and on this rock I will build my Church, and the gates of Hades will not prevail against it." (284) Christ, the "living Stone", (285) thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakeable rock of the Church. His mission will be to keep this faith from every lapse and to strengthen his brothers in it. (286)
I'm not surprised that you might be confused by the choice of words in the three seperate Paragraphs. If all else fails, try Scripture.
