That video and their speaking in supposed tongues is a ridiculous sham. Its not Christian and has nothing to do with genuine Christianity no matter what they call themselves.
Tongues that were spoken in The Bible were known languages but not previously spoken or known by those men who spoke them on the day of Pentecost. It wasn't just a bunch of jibberish, it wasn't taught and it was only spoken with Jews present.
However wrong they are, its still their children to raise. At least they aren't teaching their kids to blow themselves up in order to get to heaven.
"If ye love wealth greater than liberty, the tranquility of servitude greater than the animating contest for freedom, go home from us in peace. We seek not your counsel, nor your arms. Crouch down and lick the hand that feeds you; May your chains set lightly upon you, and may posterity forget that ye were our countrymen."
Samuel Adams
