Please elaborate on the aspects of charismatic theology that make you feel uncomfortable.
I have already done that, although it's across two different threads, one on Bethel and one on suffering.
I don't believe their supernatural claims concerning healings and resurrections. They promote the idea that healings are guarantees in this lifetime, and that they are entitled as believers to them. They claim that they can do all the miracles of Jesus individually. They believe that there are apostles and prophets today, and often use this claim to exalt themselves. They do not believe that suffering is an integral part of being conformed to the image of Christ. Additionally, most are Arminians and hold what I consider to be a deficient theology.
They claim God speaks to them audibly.
They often hold a two-tier view of Christianity, with the "spirit filled" ones, like themselves, on the top, and the normal Christians on the bottom.
Additionally, many of them set themselves up, in essence, like witch doctors who can deliver others from demons. They blame sins upon demon possession, rather than taking personal responsibility for them.
Of course, I realize that not every charismatic holds every one of these views, and I am lumping a wide variety of people together, but many do in fact hold these views. Just about every charismatic I've interacted with eventually conveys some claim like one of the above.
My grandmother was a Pentecostal. She basically "cursed" my aunt, speaking in some kind of weird voice, because my aunt divorced her husband due to childlessness and alcoholism. She later had a child by a second husband, and the child had cerebral palsy.
My understanding is that she thought the child was cursed because of her sin. If she hadn't been exposed to the curse of my Pentecostal grandmother, though, she wouldn't have believed that.
Now, I fully acknowledge she sinned in divorcing her husband, but I don't think God cursed the child as a result. This is the result of my grandmother's claims.
If this type of behavior were isolated to my grandmother, I wouldn't have a big issue with charismaticism but it is not. There are all kinds of immature, idiotic claims made by charismatics. Many of them think God is their cosmic genie, and if they declare something, it's going to happen because they are in control.
