God's got it...

Old style [essentially pre-gospel] church singing from a Faith with very deep roots. Don't presume it's continued existence isn't a complicated phenomena. Shoot, these folks aren't even protestants. Their conception of "God's Grace" sees to that.

I'm absolutely not trying to be flip, in fact I'm doing my best to show heartfelt respect for a True Church. If anyone is responsible for carrying the old "moaning" hymn and call and response praise songs into the next century, it'll be these folks. Respect where respect is due.
