A questions for Coldplay know-it-alls?

Well Viva La Vida is from a Christian point of view. It's about Jesus Christ when he went into the Garden of Gethsemene (I'm not sure how to spell that.) When it says "Waiting for my head on a silver plate," that's about John the Baptist. He was killed because a king told this lady that he would do what ever she wanted and she wanted his head. As far as I know, they don't have any other religious songs. Most of them are about family members dying or going through hard times.
