I know very little about the B'hai faith (I'm not even sure I'm spelling it correctly), but what I do know is that it teaches that ALL earthly religions are equally valid, with the corallary, of course, that they're all equally mistaken in so very many of the particulars that they preach.

What does that leave?

Well, one can still believe that a transcendant spiritual reality exists, and that it behooves all of us to transcend ego and love our neighbor as ourselves.

Do we really need to be sure of much more than that?
