The question is, who has apostolic succession that can be traced back to Jesus Christ. Peter was the rock on which the faith was meant to be built. Now, the Orthodox and Anglicans can trace a line of succession, because they can trace to when they split, but, they are still in open rebellion against God’s pilgrim church on Earth.
Funny how the same folks that sometimes say you cannot always interpret the Bible literally, somehow want to take that one verse (somewhat out of context) and interpret it with a very narrow and literal interpretation.
Some would prefer interpret that verse as something more along the lines of the “Church” will be founded on men “like Peter” who are strong spritually, endowed with leadership and faith of “a rock”. This also is reflected in the semi-autonomous nature of the early Church still reflected in the Bible, especially shown in the Apostle Paul’s writings.
An in-depth study of early church history, from the Apostolic age through the last century is fascinating - and eye-opening.
Then again, I don’t recall the term “Pope” or “Pontiff” being used by Jesus Christ either... (now to duck-and-cover)...
