Fathers:
Jerome: "The Church is founded upon Peter, although elsewhere the same is attributed to all the Apostles, and they all receive the keys of the kingdom of heaven, and the strength of the Church depends upon them all alike, yet one if the Twelve is chosen so that when a head has been appointed there may be no occasion for schism."
Cyprian of Carthage: "upon him [i.e., Peter] he builds his church, and to him hands over in trust his sheep to be fed and, although he might assign to all apostles equal power, he established one Chair and ordained by his own authority that Chair as the source of unity and its guiding principle. The remaiing apostles were of necessity that which Peter was, but the first place was granted to Peter . . . Can anyone believe that he himself sticks fast to the faith without sticking fast to the unity of Peter? Can someone be confident that he himself is in the Church if he deserts the Chair of Peter upon whom the Church is founded?"
Cyprian of Carthage: "On one man he builds his Churrch and although he assigns to all the apostles after the resurrection equal power . . . nevertheless in order that he might reveal their unity, he ordained by his own authority that the source of that same unity should begin from the one who began the series. The remaining apostles were necessarily also that which Peter was, endowed with an equal partnership both in honor and of power, but the starting point from which they begin is from their unity with him in ordr that the Church of Christ might be exemplified as one."
Isidore of Seville: "after Christ the order of priesthood began with Peter. For to him the pontificate in the Church was given first . . . He was therefore the first to receive the authority of binding and loosing . . . And since the other apostles also became equal sharers with Peter in honor and authority, they also preached the gospel dispersed throughout the world. Coming after them, there succeeded the bishops, who have been set up in the seats of the apostles."
Bede: "although it may seem that this power of loosing and binding was given by the Lord only to Peter, we must nevertheless know without any doubt that it was given to the other apostles . . . Indeed even now the same office is committed to the whole Church in her bishops and priests."
Augustine: "It's clear, you see, from many places in scripture that Peter can stand for, or represent, the Church; above all from that place where it says, To you will I hand over the keys of the kingdom of heaven . . . Did Peter receive these keys, and Paul not receive them? Did Peter receive them, and John and ames and the other apostles not receive them? Or are the keys not to be found in the Church, where sins are being forgiven every day? But because Peter symbolically stood for the Church, what was given to him alone was given to the whole Church. So Peter represented the Church; the Church is the body of Christ."
Augustine: "If it was said to Peter alone, Peter alone did this; he passed away, and went away; so who binds, who looses? I make bold to say, we too have these keys. And what am I to say? That it is only we who bind, only we who loose? No, you also bind, you also loose. Anybody who's bound, you see, is barred from your society; and when he's barred from your society, he's bound by you; and when he's reconciled he's loosed by you, because you too plead with God for him."
Leo the Great: Just as Peter became rock through participation with Christ, in a similar way the other apostles were granted authority only through participation with him. "Certainly the right to use this power was conveyed to the other apostles as well . . . Yet not without purpose is it handed over to one, though made known to all. It is entrusted in a unique way to Peter because the figure of Peter is set before all the rulers of the Church . . . for the aid of divine grace is ordered in such a way that the firmness given to Peter through Christ is conferred upon the apostles through Peter." Thus for Leo, Peter "received the fullness of blessing . . . so that, in loosing or binding the petitions of any whatsoever, only that should be ratified in heaven which had been settled by the judgment of Peter."
