CCC 424 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.
You don't agree with the Catholic catechism?
I assume a certain level of scriptural literacy, as well as English grammar, and so, perhaps, am more terse in my comments than you require. Try reading in your Bible both before and after the portion the Catechism quotes. Messiah blessed Simon. Messiah called Simon by the name Peter, a Greek rendition of the Aramaic name, Cephas, He already gave Simon much earlier, and promised to build His church on this rock. Messiah promises to give Peter the keys to the kingdom of heaven and the power to bind and loose. At least you are reading the Catechism of the Catholic Church. I hope that you can benefit as it is do very well written. At least it will not harm you, and if you can trade cynicism for love you shall prosper indeed.
Let me recommend this portion and see if the answer to your awkward question comes to you.
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 unshakable rock of the Church. His mission will be to keep this faith from every lapse and to strengthen his brothers in it.286
