Most Catholics and crypto-Catholics shan't understand any of it. Sad, really.

I'm not Catholic. I really don't know where you're getting that concept from.

You can still be Catholic without revering the Antichrist Beast Pope. This is called crypto-Catholicism, and it takes many forms. Futurism, Praeterism, Satan's Little Season, the Rapture. That's all Catholic doctrine that was introduced to the Protestant denominations of Christendom.
