Just skimmed through first pages of this thread--fascinating views!
I agree, there should be a "spiritual" category as well. Being spiritual does not necessarily mean being "religious".
My family is a crazy mix: I was raised as a child in the Presbyterian church until my Dad decided he was an atheist (easy for him, he's an engineer with that logical mind), grandmother and her family Jehovah's Witnesses, other grandmother Presbyterian, mother kind of agnostic, I think, one brother converted to Catholicism and the other is head of the Religious Studies Dept. at a college, and comes closest to the most spiritual person I know--yet is not a member of any religion. He has written books and is one of the leading scholars on Native American religion/spirituality, meditates an hour a day, believes in a kind of magic, dream interpretation and personal spiritual transformation, and is a Hermetic. Wow.
I only attended church a few times from teen years on, but always had feelings of the spiritual. That is something intangible and unmeasurable. When my husband and I had our first child (now 19 years old), I began to think about religion again--how did I want to raise our child? It took me on a quest. I wanted him to have the right values but not be brainwashed. I felt (and still feel) there is some kind of supreme Intelligence that can't be defined by our mortal minds. Things have happened to me over time that can't be explained. One is our daughter, who was born with a major heart defect (transposition of the great arteries). She went under the knife at 9 days old. I was on my knees, begging God to protect her and I swore I would do whatever was the will of God. Liana came through surgery not only with flying colors (she was the 21st patient to undergo the new surgical technique), but now at age 13, she is absolutely normal. Her cardiologist proclaimed she is the healthiest patient he has and no doctor could detect that she'd had anything wrong with her heart, if they didn't see her scars. Of course, an atheist would proclaim good surgical technique, and I would agree -- except there is an unkown "something" that I can only describe as feeling--that everything would be alright, I felt it immediately after I first got the news of her defect, and was calm and "knew" (sensed?) she was going to be fine. But my logical mind is the one that was on the knees, begging.
After all of that, when she was about 3, I discovered the Baha'i Faith, which I joined after only a few months. It holds the answers I seek, has given and continues to give a base of morals and values for my children (and me), and although I'm not strongly religious, I can never *not* be a Baha'i. If you don't know what that is, just go to bahai dot org. Basically, it is the belief that there is only one race, the human race, equality of all people (men and women in particular), all religions have validity, religion and science can agree, and of course, the Golden Rule--which is in every major religion.
That's my story!
