Being a reformed theologian does not necessitate one be a true Christian. How many people? You seem to use this line quite often and now I am curious as to your evidence. Having a large following also does not necessitate truth.

Charismatics, at least ALL I know do not support Sola Scriptura instead supporting continued revelation. An incredible majority are Pelagian/Arminian as well. The entire movement is based upon some very grievous interpretations of scripture due to the notion that the all you need is yourself and a Bible for truth. How about that second working of the Spirit or the belief that tongues MUST follow baptism of the Spirit? Nearly the entirety of charismatic theologians are dispensational. I could go on, but suffice it to say that I personally believe that a vast majority of charismatics are simply deluded.

God bless,
