My most recent response to "Spiritual, but not religious"
I am not a big fan of this whole religion is bad, spirituality is good point of view. Like many things it is an issue of social location.
Where I live, lots of upper middle class people buy spiritual products, read spiritual books and go on spiritual retreats, effectively insulating themselves from the struggles of most people in the world. They do not want to hear about current events, poverty or other problems because they are too busy being spiritual.
Sometimes, as a way of mixing up people's expectations I say "I am religious but not spiritual." Ultimately, I am a rationalist and don't really believe in supernatural dualism. In as much as religion is ethics, dedication and committment while spirituality is private individual experiences(which are oten mixed up with products and services that people purchase) I will often choose religion over spirituality. I will choose making a difference over mysticism any day.
Of course it is actually more complicated than this. WIthout spirituality, religion can decay into meaningless ritual (or a meaningless activism of gestures for that matter). I like to call it the knowledge of the spritiual fact of human solidarity versus the fiction of nations, races, classes and creeds. (even UUs tend to have difficulty with the nations part of this) All of us, human and nonhuman animals and all things come from the same source. This knowledge permeates and serves to inform all that we do. If this knowledge does not serve to bind us back together (look at the prefix re and the stem lig in the word religion) spirituality becomes just as shallow as meaningless ritual
What ever makes you feel whole, I support. But whatever helps you take your wholeness to the task of helping others be whole, I support even more.
