Which is more important? Personally, I'm all for spirituality over organized religion.
My place of worship is the Church of the Sunday Morning Long Run, where I tend to feel more connected to a greater force than I would sitting in a pew singing hymns and having someone try to interpret scriptures for me.
Religion seems to be too devisive to be productive in its intended sense and -- whether I'm right or wrong -- I always get the impression that "religious" people worship their church more than they worship God (or whatever Higher Power in their lives).
