+Mt 16: 13-19
When Jesus went into the region of Caesarea Philippi he asked his disciples, “Who do people say that the Son of Man is?”
They replied, “Some say John the Baptist, others Elijah, still others Jeremiah or one of the prophets.”
He said to them, “But who do you say that I am?”
Simon Peter said in reply, “You are the Messiah, the Son of the living God.”
Jesus said to him in reply, “Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father.
And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it.
I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.”

The Catechism of the Catholic Church
The episcopal college and its head, the Pope
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. “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.
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.” “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.”
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.”
884 “The college of bishops exercises power over the universal Church in a solemn manner in an ecumenical council.” But “there never is an ecumenical council which is not confirmed or at least recognized as such by Peter’s successor.”
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.”
886 “The individual bishops are the visible source and foundation of unity in their own particular Churches.” As such, they “exercise their pastoral office over the portion of the People of God assigned to them,” assisted by priests and deacons. But, as a member of the episcopal college, each bishop shares in the concern for all the Churches. The bishops exercise this care first “by ruling well their own Churches as portions of the universal Church,” and so contributing “to the welfare of the whole Mystical Body, which, from another point of view, is a corporate body of Churches.” They extend it especially to the poor, to those persecuted for the faith, as well as to missionaries who are working throughout the world.
887 Neighboring particular Churches who share the same culture form ecclesiastical provinces or larger groupings called patriarchates or regions. The bishops of these groupings can meet in synods or provincial councils. “In a like fashion, the episcopal conferences at the present time are in a position to contribute in many and fruitful ways to the concrete realization of the collegiate spirit.”
