Jn 21, 18-19 He said to him, "Follow me."

(Jn 21, 18-19) He said to him, "Follow me."

[18] Amen, amen, I say to you, when you were younger, you used to dress yourself and go where you wanted; but when you grow old, you will stretch out your hands, and someone else will dress you and lead you where you do not want to go." [19] He said this signifying by what kind of death he would glorify God. And when he had said this, he said to him, "Follow me."

(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" (Mt 16:19). 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" (Jn 21:15-17; Cf. 10:11). The power to "bind and loose" connotes the authority to absolve sins, to pronounce doctrinal judgements, and to make disciplinary decisions in the Church. Jesus entrusted this authority to the Church through the ministry of the apostles (Cf. Mt 18:18), and in particular through the ministry of Peter, the only one to whom he specifically entrusted the keys of the kingdom. (CCC 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" (LG 23). "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" (LG 22; cf. CD 2,9). (CCC 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" (LG 22; cf. CIC, can 336).
