So can a demon control the host or just significantly weaken them to fight sin?
It depends on the level of possession. Malachi Martin in his book, “Hostage to the Devil”, describes the final level of possession as being “perfectly possessed” where the demon has ultimate (if not complete) power over the individual. He describes these individuals as sometimes perfectly charming, even charismatic, but something about them is definitely “off”.
Have you ever met someone and think to yourself, “He/she seems fine, perfectly pleasant, even charismatic. But there is something not quite right about him/her, and I can’t put my finger on it…”? These kinds of demonically possessed people seem to have a magnetic personality.
The “perfectly possessed” are apparently generally pretty rare. I tend to believe that a some celebrities and even politicians may be perfectly possessed. I think it is safe to say that many brutal yet charismatic dictators throughout history were quite possibly perfectly possessed.
Sgt. Ralph Sarchie’s book, “Beware the Night”, is another excellent book on the subject. Sarchie was a policemen and lay exorcist with firsthand experience dealing with the demonic. Both books can be quite frightening to read, so you are forewarned.
How does someone get possessed by demons? What type of things do you get involved in for this to happen? I’m rather naive. I’ll keep my innocence
As someone mentioned earlier, it is a gradual process. You can open yourself up to the demonic by dabbling in occult activities like witchcraft and the like, delving into drugs and alcohol, participating in seances, etc. Ouija boards seem to be particularly harmful for some reason.
Daily Mass, saying the rosary, wearing a scapular, reading the Bible, etc. are all ways to “spiritually” protect yourself. Basically, stay on the straight and narrow.
