Short answer

Christ is the one foundation and the head of his Church, and he chose to build it on Peter, to whom he gave the name Rock. The Fathers read the rock of Matthew 16:18 as Peter, as the faith Peter confessed, and as Christ, and some of them give more than one of these readings. The readings do not compete. Peter is rock because of the faith he confessed, that faith rests on Christ, and the Catechism holds all three together.
