Naked Spirituality: A Life with God in 12 Simple Words." The groups I've been experimenting with for a couple years are built around maturing through stages similar to the "seasons" of spiritual growth that "Naked" lays out. What I have in mind is part house church, part meditation sitting, and part tough-love support group--all designed to help us maintain our "awakening" or "Christ consciousness" as we interact with others in our normal day.
So far I've found rich community in groups based on a format by James Jones and inspired by the books "Essential Spirituality" by Roger Walsh and "Integral Life Practice" by Ken Wilber and Terry Patten. As a next step, I'm drawn to the idea of mixing "spiritual but not religious" people
with the kind of open-hearted and open-minded Christians I'm meeting at
the Emerging Christianity Meetup in DC. I think they have much to teach those of us who may have thrown out the baby with the bathwater of the restrictive religions we grew up with.
