Just to make it clear:
Is there anyone who says charismatic/pentecostal movement is not a cult and is not a charismatic himself?
Its quite understandable that charismatics will say they are not a cult...
To me, the simple definition of a cult would be that they consider anyone not in their "group" to not be saved. So JW's, Mormans, COC, etc, belong to this definition. Probably Word Faith, not because they don't consider non-WF people to be saved, but because they put them down, malign them and their faith. Yep, Word Faith is a cult, by my definition.
I attended Pentecostal and Charismatic Churches the first 15 years I was saved. I saw excesses and I saw deadness. I was in a large Pentecostal Church with 3000 members, lots of outreach, but never a single "gift" of the Holy Spirit. Many considered that church "dead!" Except for the fact that so many people came to Christ - is that not a sign the working of the Holy Spirit?
Anyway, I came to the conclusion that I did not believe what I was seeing in most of the churches were actually the gifts of the Holy Spirit. Instead, I think most of it was from the self and ego. That was not everyone, of course. I met some very wonderful, spirit led people. But the general milieu in those days (80's and 90's) was exhibitionism masquerading as people operating in the gifts.
However, although I walked away from that, I never heard one person say that non-charismatics were not saved. True, they put them down, said their lives were empty, but they did not ever say they weren't saved. (Well, except the Oneness or United Pentecostals, but they believed other Pentecostals weren't saved, too, because they didn't follow their twisted theology and ideology. So, let's not include them in the discussion.)
In conclusion, as a former charismatic, non-Pentecostal, I do not think that the Charismatic movement is a cult.
I hope that works for you!
