Let's examine the countless popes in Bible alonism, for every protesting denomination there is a self appointed figure who proports to interpret the public revelation of Scripture for all. It doesn't matter if he or she interprets doctrines in complete confliction to all others.
Catholics only have one Pope, and a singular Apostolic tradition to explain Scripture
Squabbles?
Even the devil can quote scripture to suit his purpose. This was demonstrated at the temptation of The Lord in the desert.
Bible alonism birthed relativism into the modern world, where each man thinks he can interpret what the Bible means to him.
Forget Truth setting you free, fallible human opinion is just as good they said.
Forget every heretic quotes scripture to support his pet heresy.
It's not the Authority of Scripture at question, it's the Authority of those who interpret Scripture that matters.
The Catholic Church has Apostolic Authority, first demonstrated by determining the Canon itself, no one else did that.
No, the RCC does not have Apostolic Authority, they imagine from Scripture what is not there.
You should know by now we are having none of this, Cathode.
