Your question stressed me
Before opening the thread I had sworn it is. Now, I have had a deep look into google. But I found no proof. And there are no song lyrics online. Therefore I have read every booklet of my four "Katagory V" CDs. This is good for my english knowledges
The answer is not easy. First softly "proof": The band is from Salt Lake City (Mormons!). Secondly: They are singing about different questions of life (life, death, lies, friendship and so on). They do it in a style, somebody could think, the lyrics are christainly inspired.
I found one song only with obvious explicit christianly content. The song is called "Sands of Time" from the CD "Hymns of Dissension":
Can you see the full moon risingCan you see the sun turn blackCan you see the messiah's coming backHope, you understand, what I have written in "german englisch"
