Lyric discussion by Hafgan 

I believe I see the connection of the 'Agnus Dei'-part and some of the lyrics. I think The song is about a mix of Catholic beliefs and Native American beliefs. There is no dubt thers some Catholic involvement in these lyrics.

I've heard that some N.A. took some of the Catholic sacraments into their beliefs (I recommend the short-story "The Man to send Rain Clouds" by Marmon Silko for further understanding of this.)

I think 'Healing waters' refers to the Catholic sacrament, and the N.A. use this to never get thirsty in the afterlife e.g. "Bury all my pain".
