Until you can show us Sola Scriptura in the Bible, you should speak no further.
There is no Pope in the Bible
There is no "Trinity" in the Bible, either. There is no table of contents for your Bible specified in Scripture. But you still use a Bible.
And unless you can show me something of mutually-agreed authority (perhaps the Catholic Bible?), then I refuse to believe the Pope has any authority. It simply looks pulled from one’s butt.
