He has described himself (in the past) as being "spiritual but not religious" and said that he "doesnt believe in organized religion". Many of the songs on Core deal with this- Naked Sunday, Wicked Garden, Sin, Where The River Goes, all have religious undertones. He seemed to have a lot of confusion when he was younger and question a lot, as most younger people (including myself) tend to do ("when all is over and we return to dust, who will be my judge and which one do i trust?"). He does mention God and religious metaphors from time to time in lyrics, and its always interesting to me that with each album they seem to grow and become better defined and less cloudy. Its quite possible he has become more religious or even catholic, etc. Im sure his beliefs have changed a lot since he got married & had a family too.
