Good question. I recall a bumper sticker I saw that said Fundamentalist agnostic: I don't know and neither do you. Or some variant. When I have been to church lately, I do what you do. I also don't say grace with family at holiday functions. I have been asked by my nephew, why don't you go to church, uncle Phil? My spouse and I actually do Unitarian/Universalist services, but we are not doing them from a christian angle. So I guess I'm spiritual but not Christian. I can go on further, but only will do so if asked.
