Jesus asked, Who do you say that I am? Peter responded, You are the Christ!, which means the promised Messiah. Jesus was very clear that the Father had revealed this to Peter. Jesus is building His Church on the miracle that ordinary people, like Peter, can confess something as wonderful as that. In fact, the Church is filled with ordinary people who do extraordinary things because they confess Jesus as Messiah and are empowered by the Holy Spirit.
