The Lord said to Peter, "Thou art of stone." For the strength of his belief, and for the steadfastness of his profession he received that name, because he had attached himself with firm mind to Christ, who is called 'stone' by the apostle Paul. "And I will build my church upon this stone:" that is, on that faith which thou professest. All God's church is built on that stone, that is, upon Christ; for he is the foundation of all the fabrics of his own church. All God's churches are accounted as one congregation, and that is constructed of chosen men, not of dead stones; and all the building of those living stones is founded on Christ; for we, through that belief, are accounted his limbs, and he is the head of us all. He who builds not from that foundation, his work falls to great perdition. Jesus said, "The gates of hell may not aught against my church." Sins and erroneous doctrine are the gates of hell, because they lead the sinful, as it were through a gate, into hell-torment. Many are the gates, but none of them can do aught against the holy church, which is built upon that fast stone, Christ; for the faithful man, through the protection of Christ, avoids the perils of diabolical temptations. He said, "I will commit to thee the key of the kingdom of heaven." That key is not of gold nor of silver, nor forged of any substance, but is the power which Christ gave him, {371} that no man shall come into God's kingdom, unless the holy Peter open to him the entrance. "And whatsoever thou shalt bind on earth, that shall be bound in heaven; and whatsoever thou shalt unbind on earth, that shall be unbound in heaven." This power he then gave to Peter and likewise afterwards, ere his ascension, to all his apostles, when he blew on them, thus saying, "Receive the Holy Ghost: the sins of those men which ye forgive shall be forgiven; and from those to whom ye refuse forgiveness, forgiveness shall be withdrawn." The apostles will not bind any righteous man with their anathema, nor also mercifully unbind the sinful, unless he with true repentance return to the way of life. The same power has the Almighty granted to bishops and holy mass-priests, if they carefully hold it according to the evangelical volume. But the key is especially committed to Peter, that every people may with certainty know, that whosoever deviates from the unity of the faith which Peter then professed to Christ, to him will be granted neither forgiveness of sins nor entrance into the kingdom of heaven. OF THE PASSION OF THE APOSTLES PETER AND PAUL. We will after this gospel relate to you the lives and end of those apostles in a short narrative, because their passion is everywhere fully set forth in the English tongue.
