I know this topic hasn't been updated in many years, but it concerns me. I have always had a lot of irrational fears as a young man concerning supernatural phenomenon like this. Roman miracles, and even phenomenon like reincarnation and aliens always left me tormented and disturbed, being that we were always taught growing up that it was demonic.
There are no real accounts of major cult leaders being delivered from their deception. It seems if you are in a cult or founded one, you are likely going to stay that way until you die. Also, no stories of anyone being tortured during alien abductions and then finding Jesus afterwards or realizing it was all a deception, and I do believe that many UFO related events like that have happened, and are either demonic or real. The reason it causes me so much fear is because it validates the power of institutions or beings who I see as being a bastion of mind control and fear. The new age and alien phenomenon in my opinion is a valid alternative explanation to what goes on in the world besides just Satan. I never saw a reason to think that if there are religions who perform miracles under the devil, then why not Christianity being a conspiracy of some malevolent being? I don't think we can actually disprove the possibility of some otherworldly beings outside of what Christianity claims to exist having some influence or control over the world. In other words, things like the resurrection of Jesus and the bible itself may contain deceptions and lies even if the miracles may have happened. Growing up suffering religious abuse and confusion left me permanently damaged in my mind that God truly was an instrument of fear and control, and my doubts have not went away. Seeing documentaries or information on alien phenomenon also left my mind troubled deeply. I never felt I could ever have enough trust in God after that, or that the new age explanation that the biblical God is some opressive demiurge type being like in the Matrix could explain why we must resist it. I could find many reasons to believe that what is taught in Christianity is truly irrational and destructive, even in spite of being self-professed Christian who believes there is in fact some miracles done in the name of it. Given my misfortunes with religious people and institutions, it was like a dream to find some kind of escape from this nightmare that had no hope, that is, the Christian faith. I tend to read the bible and find things that seem comforting, then hear people or figures in my imagination telling me it is a lie and I don't deserve it or am created to be tortured by God.
That being said, the bible speaks of principalities of demons residing in certain nations or bodies. We were always told because of sensational stories that Romans had more power because of the extravagant tales of their exorcisms, and Protestants or others were a fraud. But this allegedly validates any kind of false theology they teach and left me confused. Someone mentioned Padre Pio's rejection of the church in the beginning of his ministry is because he is the second Christ, his life meant to parallel the rejection of Jesus by the Jews, up until his eventual canonization, however, that would mean whatever antagonism he taught towards Orthodoxy would be valid. They say his stigmata was real because you cannot heal so quickly between the appearances of those stigmatas if you try to burn yourself.
I have had Roman catholic priests lie to me numerous times of witnessing astounding exorcisms, but also had an encounter with our local (emotionally abusive) bishop before he retired, who said he did not remember the last time he ever authorized an exorcism in the long decades since had been in office, and he had only ever performed one himself which was no different than what Bob Larson does. It wasn't like what they show on the Exorcist. I also had a former Roman priest who became Anglican tell me Roman priests, like pentecostals, embellish a lot of what they do. He said he was once exorcised by a Roman priest because of occult influences he had from his relative's involvement in a masonic lodge. There was nothing extravagant. He said a lot of priests don't even have much faith in this stuff anymore and the church is lacking exorcists in general. I have found a lot of Romans to be generally dishonest, rude and corrupt in general. I have my share of hurt from being demeaned by them in person, which has been part of my current mental health struggles.
