Why "Spiritual Naturalism"?

Our response to the natural world is one of reverence and humility in the face of a mystery that transcends empirical knowing-now, certainly, and perhaps forever. "Agnostic" does not do justice to the celebratory aspect of our position. Nor does "pantheist" adequately express our sense of what nature hides. "Creation-based spirituality" has a respectable pedigree, although "creation" hints at an anthropomorphic Creator. "Religious naturalism" gets close to the mark.
