What do I think about those videos? They're junk. And I am not... a Roman Catholic.
Because of the Protestant branches separating from the Catholic Church in past centuries in Europe, the persecutions by the RCC upon them (even wars), many of the Protestants thought then that the pope was the antichrist prophesied in the NT. He's not.
Judaism is also on that false boat against the RCC because of claimed persecutions upon them in the past also by members in the RCC. And since orthodox Jews are intent upon building another temple in Jerusalem and starting up Old Covenant worship again, with animal sacrifices, they would naturally want the world to think doing that is to truly follow God, when it is not.
Jerusalem is the end time prophetic barometer for the end of this world, not Rome.
