It’s even much worse than you present in your link. The PTR ruse was created by the very Little Horn/Antichrist power that these Christians warn against. They are being led to the slaughter and don’t even realize it. Satan has them hopelessly fooled. The PTR theory is straight from Satan’s mind and will cause most Christians, who are alive at the end of the world, to lose their salvation. They totally discount the Antichrist and Mark of the Beast, because of their claim that they won’t be on the earth to be affected by them. They are also WRONG on their interpretation of Daniel’s 70 weeks and anything that has to do with a prophetic end-time Jewish nation of believers that convert to Christianity, 7 years, etc... It is ALL contrived and deflected by the Jesuits/Catholic church in their crafted theory (theories) of Futurism and Preterism. They invented them. It’s historical fact that the PTR believers refuse to acknowledge.
The book of Daniel says that the Little Horn power comes out of Pagan ROME and then lasts until the end of the world, which is something else that the PTR believers also refuse to acknowledge.
