XUSCR, you state
quote:
For argument sake only, let's assume that the scriptural references to Peter as the rock of Christ's church on Earth and the crazy statements about him having the keys to the kingdom and being able to loose and bind all mean what Rome says they mean.
You then draw the inference that Scripture mandates the RCC version of doctrine.
Buteven if we were to accept the RCC take on these scriptures, RCC doctrine is not necessarily verified.
Even with your take on the meaning of these Scriptures, you have to assume that Peter was the sole rock upon which the church would be built, an assumption which is contrary to the history recorded in Acts where both Paul and James were treated by the early church at least Peter's equals. There is even some evidence that Mary Magdalene was held in at least as high an esteem by the original as Peter. So either the factual record is wrong, or the early church did not understand Jesus' sayings as well as thr RCC does today.
You have to further assume that Peter in fact was the first bishop in Rome, an assumption that finds its basis not in the historical record but in later tradition. There is no contemporaneous documentation that Peter travelled to Rome, much less that he assumed a bishopric there. Traditions based on hearsay are less than persuasive in establishing doctrine as certain.
Further, you have to assume that the bishop of Rome at the time of Peter was the same office as the Bishop of Rome as presently constituted. This cannot be done successfully, as the best evidence is that the early popes were viewed completely differently than those following Constantine, much more so those of the "dark Ages' and even more so today. If the office of the Bishop of Rome is different today than thebishop of Rome at the time of Peter, then how can you say the RCC doctrine is correct? They have left the rock on which the church is to be built, even under the RCC understanding of these scriptures.
So, no, the Protestants are not hoist on their own petard in their reliance upon Scripture, even if the RCC interpretation of these scriptures is followed.
