Satan fears seeing the Catholic Church totally reunited more than anything other than the return of Christ.
The One, Holy, Catholic, and Apostolic Church Jesus Christ Himself founded whipped Satan and his well entrenched demons once already by leading the world to Christ and could do it again. Satan knows that even though the Self Alone crowd are too blind to see it.
That would set Satan back to the same point he was at when he pumped up Iz Lame to counter Christianity with violence instead of faith in the demons behind pagan gods that had worked so well for so long prior to Christ. A setback like that would mean while Satan has been keeping a lot of people out of heaven, he hasn't made any progress other than that for fourteen hundred years.
So, of course if Satan can he will raise up a counter religion. He tries all the time to do so. People who one minute brag about how many people are leaving the Catholic Church and the next blabber about the Catholic Church being used by Satan are really funny.
Satan will use whatever is most effective and according to the same people who see the Catholic Church as evil, what's most effective isn't the Catholic Church. It's the very anti-Catholic emerging/evangelical/spiritual Churches. So, that's what Satan will use, whatever markets best in the ten major mega churches. It would be far easier for Satan to merge mega churches that ignore most sin and that appeal to Mooze Lames for a number of reasons than to use the Catholic Church. Especially since those mega churches all grew out of the Protestant and Protestant derived heresies of Self Alone.
If it's possible, it'll be possible because of Satan raising up some new, super spiritual, Televangelist who can heal right through your big screen TV to prophecy that Christ isn't going to Rapture Christians, he's going to return and rule rather than judge just any day.
So what is your solution against the Mega Churches???
