Is it any wonder when you look at how much hinges on Peter being that "rock"??? Yet, even IF that was what Jesus meant, it still wouldn't automatically mean every man after Peter that Catholics claim were his successors were handed that same authority from Jesus. Quite a bit of presumption going on.
In other words, it ultimately comes down to, ‘Because I say so,’ not ‘because the Apostles said so.’
Ultimately, if Roman doctrine contradicts what Jesus and the Prophets and Apostles actually taught—ESPECIALLY in regards to justification and worship—the Romanists CAN’T be the ‘one true church.’
And all the shouting in the universe from the usual suspects can’t change that.
