cos the Bible tells me so
Interesting. You seem to be sitting in judgment of the RCC's selection of a "pope" and determining that the Bible tells you everything is going to turn out all right, irrespective of what they have done. Such a position would imply that you have a personal interpretation of the Bible which overrides Rome, since Rome claims to control interpretation.
While you are using the same logic most biblicists use to evaluate Rome, you are certainly in conflict with the mother ship. They claim to have control over the interpretation of that Bible and would argue that they could not possibly make a mistake in selection. But, here you are saying the Bible trumps Rome...hmmm. Welcome to reality.
