man, was just Gods instrument, He guided mans hand, so the scripture, is indeed infallible. To say otherwise, is calling God a liar. period. Scripture is infallible, it is in our interpretation of it, that errors come, not by the writers, but our understanding.
Good job giving the exact verse, its matthew 16:18-19, "and I say also unto 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 unto thee the keys of the kingdom of heaven, and whatsoever thou shalt bind on earth, shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven"
So, you see, you are at least partly right in that Jesus, tasked Peter with starting the early, church, which we can see He did in Acts. What you do not see, anywhere in acts-which is expressly written to the church, on how the church was to be run, was Peter fulfilling the role of "pope" in fact, nowhere in acts, does it say that there will be a "infallible" person leading the church. nowhere. Its not in there. So to use those verses to say that Peter, and all the "popes" that followed him, received "infallible" words of God directly from God, is an misinterpretation of the verse.
To say that your "not going into that even though youve done the research" is copout, it really is, shows you havent really done the research. And the first mention of the catholic church in any historical document didnt appear till some 80 years after Jesus died-long after Peter died. And, from research, the early catholic church, was nothing like todays-the early catholic church, was a very Bible Oriented church, the pope wasn't this person that got visions from God, but more of just a leader who admitted their fallicies. The early catholic church, was modeled after the church in acts, and was instrumental in putting together the holy Bible.
The problem was, that over time, the catholic church turned away from scripture, and towards church tradition. It wasnt a sudden thing, it was a slow degradation, hitting probably a new low when Martin Luther posted the 95 Thesis on the church wall in 1517, all 95 were solid, Biblical problems with the catholic church. The problem was, the church never learned from these, and just continued until what we have today-a church that stands more on tradtion, and what the pope says, then on what the Bible says, which is why were having this debate. We need to get back to scripture-not church tradition. It is church tradition, that is flawed, and infallible-not the Bible.
