Not even close. If you listen to the lyrics you hear some spiritual stuff in there. But by no means "christian." In an interview Maria Brink said "I don't even know what makes you a Christian band. I mean we all believe in God and I write about God, and we have a spiritual side, but I don't think we're called a Christian band, not that I know of anyway"
That does not constitute a christian band to sing about god. There has to be some sort of message in there other than believing in god and writing about it.
