I'm fairly convinced that the "tongues" in Scripture are actual human languages, and that the ones we see in the charismatic movement today are either gibberish, or demonic.

I have had Charismatic friends whom I do believe to be genuinely regenerate. I don't think this is necessarily a salvation issue unless one elevates "tongues" or any other form of "special, personal revelation" to a plane comparable to (much less equal to or higher than) Scripture. But many Charismatics, like many other Evangelicals, are semi-Pelagian, and I do think this is a salvation issue; the person who thinks he or she is responsible for their own salvation still has self as his or her "God," and not God as He really and truly Is.
