I personally have dealt with many possessed people...people declared MPD and institutionalized by the State...who traced the origin of the entrance of the evil spirits to the time they first "spoke in toungues".
I have heard the devils speak, calling Jesus a liar, claiming the person they possess, distorting the body of the possessed one.
These are people who met Satan in church, in a Charismatic church, in a toungues talking church.
One was delivered, and went to the state facility every weekend, preaching to the inmates. One of them was his daughter.
One had voices, idk how many. She would fall into a trance, staring blankly ahead, repeating what "the voices say".
I am working with an Indian now, who had a "mental breakdown", in a roomfull of people "praying in their heavenly language". He has had thoughts of murder, rage and hatred, since, and is now a felon, due to expressing these thoughts.
He was at a charismatic bible college, training for the ministry.
Of course, being Armenian, they blamed him when he crumbled, telling him his faith faltered.
What an evil movement. Wizards, nicolaitans, shaman, Balaams.
You will never again convince me that God is in your evil, I have seen too much.
Anathema.
