Being privately spiritual but not religious just doesn't interest me. There is nothing challenging about having deep thoughts all by oneself. What is interesting is doing this work in community, where other people might call you on stuff, or heaven forbid, disagree with you. Where life with God gets rich and provocative is when you dig deeply into a tradition that you did not invent all for yourself.
