I don't think it's that religious. Bells in America is more of a symbol of 'liberty' than religion, I think that's what Jovi was going for. I agree Welcome is a far more religious song. What I like about BoF is that it can be interpreted as patriotic without explicitly being so, much like Undivided. Bon Jovi never takes the nauseating Mellencamp root.

The most 'spiritual', or at least philosophical Jovi song is easily and by far STBI.
