Amazing that you think Matthew 16:19 is non-biblical and mythical.
Mat 16:19 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 on earth, it shall be loosed also in heaven.
What are the keys to the Kingdom of Heaven???
Never said that. Its the CATHOLIC view of this verse that is non-biblical and mythical. There is nothing in the Keys of the Kingdom that apply to Popes or the Catholic Church. It was applied to Peter and Peter ALONE.
"....nothing in the exegesis, leads one to conclude that the office was meant for anyone other than the apostle Peter. The findings have indicated no real basis to assume that the text is outlining the basis for a succession of supreme pontiffs who claim their authority from Peter."
"This is important because the Catholic Church maintains that the institution of the papacy is of divine, not human, origin. Matt 16:18 is used to substantiate this. If this claim is true, then one would certainly expect to find the “doctors of the church” referring to the institution of the papacy and linking it to this verse. For the most part, though, (with the exception of Jerome and the bishops of Rome), such references are not present in the writings of the fathers. Yes, it is true that Rome possessed a position of pre-eminence in the early Church; no historian or theologian would dispute this. However, the question is whether the primacy promised to Peter in Matt 16:17-19 and actually exercised by him is to be transferred to bishops of the Roman Church."
