My Demonic/Sludge possession in a Christian Church !!!

[Melektaus]

The christian bible says that "a prayer of Faith will heal". Prayer is Psychic Energy, same with faith. "the kingdom of Heaven is in you". We heal ourselves.
The Parasite ( sludge ) was a weak level entity ( hungry ), so could easily be cast out.
A powerful Demon, well, to the Christian, "good luck with that one".
And, if the person wants the Demon ?
As one preacher said about a lady,, "you could not cast the Demon out of her. She wants that Demon, and as long as she wants it she can have it".
And as far as knowing when a person is possessed by a Demon, a parasite/sludge, an angel imitating a Demon ( if they do that ), or mental illness, or a spell obsession by a sorcerer on the possessed person, I suppose one can only learn through trial and error.

there are ways to tell but you have to hone your senses enough to.
