Thanks for another thought provoking post. I am not convinced that religion and spirituality can be truly separated, they seem to me to be two lungs in the same chest. I think religion is not a category, as in dachsunds and terriers are dogs, but something qualitative. There is good religion and bad religion. A bad religion misses the mark, and should not really be given the name religion.
A religion without spirituality, or spirituality without religion seem to me incomplete.
