Most common would be speaking in tongues.
I think the easiest way to distinguish Pentacostals/Charismatics is their beliefs in how the gifts of the spirit operate in believers today.
I grew up in a pentecostal/charismatic church and I'm tempted to tell you to put me in there but it's not very accurate anymore. Now I usually attend an Episcopal church but that's not in your list, and I don't know if I'd characterize myself as that anyway. I suppose boring, old "Protestant" is where I should be. It's like the catch-all for people who don't belong anywhere else.

Are you tempted to put csguy in the Catholic category? :chuckle:
