None of your lovely quotes diminishes the primacy of Peter, nor do they diminish the Petrine Ministry.
I am happy to provide a number of lovely quotes myself, however, this shouldn’t be a battle of cut and paste. However, for context, here are the relevant passages. I recommend using this link (http://www.usccb.org/beliefs-and-teachings/what-we-believe/catechism/catechism-of-the-catholic-church/epub/index.cfm)as it hotlinks to the footnotes and other relevant materials.
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.”8 On the rock of this faith confessed by St. Peter, Christ built his Church.9 (683, 552)
552 Simon Peter holds the first place in the college of the Twelve;283 Jesus entrusted a unique mission to him. Through a revelation from the Father, Peter had confessed: “You are the Christ, the Son of the living God.” Our Lord then declared to him: “You are Peter, and on this rock I will build my Church, and the gates of Hades will not prevail against it.”284 Christ, the “living stone,”285 thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakeable rock of the Church. His mission will be to keep this faith from every lapse and to strengthen his brothers in it.286 (880, 153, 442, 424)
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.”287 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.”288 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 apostles289 and in particular through the ministry of Peter, the only one to whom he specifically entrusted the keys of the kingdom. (881, 1445, 641, 881)
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. (553, 642)
Thanks for PROVING that Cathoplicism can't seem to make up it's collective mind on things.
