The catechism states that Christ built his Church on Peter's confession:
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.

CCC 1444 In imparting to his apostles his own power to forgive sins the Lord also gives them the authority to reconcile sinners with the Church. This ecclesial dimension of their task is expressed most notably in
Christ's solemn words to Simon Peter: "I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."
"The office of binding and loosing which was given to Peter was also assigned to the college of the apostles united to its head."
CCC 553 Jesus entrusted a specific authority to Peter: "I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."
The "power of the keys" designates authority to govern the house of God, which is the Church. Jesus, the Good Shepherd, confirmed this mandate after his Resurrection: "Feed my sheep." The power to "bind and loose" connotes the authority to absolve sins, to pronounce doctrinal judgments, and to make disciplinary decisions in the Church. Jesus entrusted this authority to the Church through the ministry of the apostles and
in particular through the ministry of Peter, the only one to whom he specifically entrusted the keys of the kingdom.
CCC 880 When Christ instituted the Twelve, "he constituted [them] in the form of a college or
permanent assembly, at the
head of which he placed Peter, chosen from among them." Just as "by the Lord's institution,
St. Peter and the rest of the apostles constitute a single apostolic college, so in like fashion
the Roman Pontiff, Peter's successor, and
the bishops, the successors of the apostles, are related with and united to one another."
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.400 "The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head."401 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.
882 The
Pope, Bishop of Rome and Peter's successor, "is the perpetual and visible source and foundation of the unity both of the bishops and of the whole company of the faithful."402 "For the Roman Pontiff, by reason of his office as Vicar of Christ, and as
pastor of the entire Church has full,
supreme, and universal power over the whole Church, a power which he can always exercise unhindered."403
883 "The
college or body of bishops has no authority unless united with the Roman Pontiff, Peter's successor, as its head." As such, this college has "supreme and full authority over the universal Church; but this power cannot be exercised without the agreement of the Roman Pontiff."404
884 "The college of bishops exercises power over the universal Church in a solemn manner in an ecumenical council."405 But "there never is an ecumenical council which is not confirmed or at least recognized as such by Peter's successor."406
885 "This college, in so far as it is composed of many members, is the expression of the variety and universality of the People of God; and of the unity of the flock of Christ, in so far as it is assembled under one head."407
