This opening paragraph is a work of fiction. But I agree that Christians don’t need the Catholic ORG Magicsteeringthem. There are some nice reference books in the Vatican vaults though ...
Protestants claim the Bible is the only rule of faith, meaning that it contains all of the material one needs for theology and that this material is sufficiently clear that one does not need apostolic tradition or the Church’s magisterium (teaching authority) to help one understand it. In the Protestant view, the whole of Christian truth is found within the Bible’s pages. Anything extraneous to the Bible is simply non-authoritative, unnecessary, or wrong—and may well hinder one in coming to God.
When a lie is most effective it has the false intermingled with truth. The last sentence in that paragraph is nonsensical.
