. Actually, you cannot take one phrase from the Bible while ignoring the argument being posited. Rome suffers badly from this error. Re: Matt 16...please, where is Rome in this?
Simon Peter answered and said: Thou art Christ, the Son of the living God. And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven. And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.The keys, as is shown in Is. 22, are the symbol of the Master of the Palace or the King's Vicar. An office is here bestowed upon Peter. Acts 1 also shows that the office of the apostles is not limited to the original twelve but is continued by their successors. The Bishop of Rome, i.e. the Pope, is the legitimate successor of St. Peter as the holder of the keys.
