When I used to volunteer at a homeless shelter, there was a young girl I will call her Mary) and her fiance that were unfortunately having to stay there. Something about Mary's way of talking and her general demeanor told me that she might have been on the autistic spectrum. One evening, I was sitting with this girl, her fiance, and some other people in the community room. A woman came storming in, spouting gibberish. A malevolent energy was perceived by both myself and Mary.
I quietly speculated that the woman was being influenced by something of a dark nature. I was a bit nervous as that woman went and sat on the floor, still spouting negativity, swear words, and gibberish. Mary calmly said that the disturbed woman needed to be anointed. I agreed, and reminded her that we didn't have a priest on staff. She replied that if one did the anointing in the name of Christ, that it would work. She then went to her room and got a bottle of essential oil , and proceeded to approach the woman. I watched in fear as Mary drew close, fully expecting the disturbed woman to lash out at her. But from where I stood, all I saw was Mary pausing briefly in front of the woman seated on the floor, and then walking away.
I left shortly after that. The next day I was riding the bus, when I saw that same disturbed woman boarding. I watched her in shock. She spoke pleasantly to the driver, and seated herself. She was clean, and groomed and there was no negative energy around her. That simple anointing, done in perfect faith, had done the trick. That's my story about an amazing person.
