Just one other thing I wanted to say having thought further ...
Reading this thread, the impression comes of a faith which is very individual, with each person having their own sense of what they believe, how they understand what it is to be a Christian. And that is an important element.
But the other key thing about the faith is a parallel emphasis on Community, and relationships with others; i.e. living out life in a related, joined up way with other people. I live in a traditional rural village up north where the role of the church is still perhaps not too far removed from what it might have been 100 years ago. Most people go to church from time to time, the kids from the little school go regularly - no-one is particularly fervent, but it is a community thing.
The interesting thing is people say "Oh, I like church, for myself and for my kids, but its really just the community side of it I like, I don't really believe very fervently" as if, because its the community element they get something out of, this means they are not "real" Christians. But being in communion with others IS being a Christian. A good part of the faith is about DOING, not about what you THINK or believe.
I always used to go to chapel evensong at college because I loved the atmosphere and the singing. I used to say to myself, I am not really a christian I just go cos I like the music and the quiet. As I've got older, I much more tend to see God IN those things that I find beautiful. So if you feel moved by music at a church service, its not "just the music" - because the music IS God/the divine/the transcendent/holy - or whatever other inadequate label we might try to use for something that can't quite be labelled.
