I did not bother to read since it's likely a Protestant Heretic making things up. There is one Church only and it is not Protestant. Protestants do not have authority to do anything.

The Antichrist will likely pretend to be Christian and likely be some Protestant Heretic.

I expect he will show himself in about a year and there will be about 3.5 years of good times before trouble starts big and then a thousand years of peace, judgement and a new heaven and new earth. Most Protestants and all Muslims will be in Hell with Satan.

There are a few Christians mislead by Heretic organizations that will get salvation but most will not.

Jesus founded on Church and Saint Peter was put in charge as the first leader of it so he is the first Pope. Case closed 2000 years now.
