Let’s see if I can take a shot at this. I used to be very heavily into the Pentecostal/Charasmatic Church, which you will find a lot of your televangilists have backgrounds in (Pat Robertson, Benny Hinn, Oral Roberts, Robert Tildon, isn’t that enough!). I had the classic “my life was so bad until Jesus” type story, and many of the things I’m about to describ starting bothering me a lot once I started feeling better about myself. I am no longer in this movement, and no longer a Christian, but feel I can contribute here regardless.
In a nutshell, if you are a Christian and use these “powers” with faith in Jesus for the benefit of the church or potential members of the church (depends on which power) then it is ok. If you have a different faith, than it is from Satan and false.
Since we are talking about a large sect of Christianity (I refer to my church going days as being in “the cult”), I think it’s appropriate to use NT verses, specifically the gifts (powers) as described in 1 Corinthians 12:7-10.
And for information’s sake, I’ll try to expand a bit. There are nine gifts (called charims, hence the Charasmatic movement) here: Wisdom, Word of Knowledge, Faith, Healings, Miracles, Prophecy, Dicernment of Spirits, Tongues, and Intrepretation of Tongues. The problem here is that the NT doesn’t define exactly what these all entail, but that doesn’t stop them from “using” them and after spending a few years being indoctrinated into their way of thinking, I have some insight. Basically, almost all of these can be considered “pyschic” powers to some degree or another. To save space, I’ll only mention the biggies: Word of Knowlege, Healings, Prophecy, Tongues and Intrepetation. The others aren’t really talked about much (especially Wisdon, go figure).
Word of Knowledge: The ability through the Spirit to supernaturally see into someone’s life and either have enouraging words for them or tell them something they need to here. For example, the person with this gift would say “I see God breaking the chains that are holding you back, and from this day forward you will be free of that thing that is holding you back.” This can go on for a while and not seen as a prophecy, but more of a message from God into an individuals life. Another example is one the pastor told of walking through a grocery store, calling a woman by name and telling her about her cheating husband, and God wanted her to know that she is still loved even though she doesn’t think she is.
Healings: Speaks for itself. These people believe that certain ones have bestowed upon them a gift to go and heal the sick. Usually done by the laying on of hands. The most “famous” one in the church I went to would sit you down, sometimes do measurements on limbs, proclaim what is wrong with you, pray and many times proclaim you are healed. One woman had lower back pain, he sat her down, said it was caused by one leg being shorter than the other, prayed, and then claimed that one had grown and they are both the same length.
Prophecy: Very big. Basically fortune telling but it’s from God so it’s all right. I sat in with a supposed modern day “prophet” who went to each person in the room and prophesied over them, giving insight in their life and their future. For me? He said he saw me with my own ministry and I would do great things for Jesus. Talk about being off! I think he carried around Chick tracks.
Tongues: Probably the biggest. This was people speaking in different languages (if not human languages, then angelic) and was attainable by everyone if they just let their mind go. It was used in worship and to get one in the “mood” for prophecy or healing.
Interpretation: Those who claimed to understand what others were saying when speaking in tongues, not of their own mind, but superntaurally through the Spirit. Usually a message to the congregation to repent or obey or God loves you.
I think these all fall under the realm of pychic powers. However, it was always emphasized that these were gifts from God, and the person themselves had no “power” in and of themselves. The emotional (and sometimes physical) rush that occurs when these things happen is usually enough to keep the questions and doubts from coming.
