I think it’s worth noting that for most people (personally, I would say for anyone, but I’ll leave the door cracked), belief in gods isn’t a simple on-off switch. There’s a continuum, based not only on whether we believe in a god, but on what we believe about that god. If I believe in a personal deity who loves me, hears my prayers, intercedes on my behalf, and will determine my destination in the afterlife, I think anyone would say that I “believe in God.” But what if my deity is the kind that wound the clock at the beginning of time, setting in motion the events that led to human evolution (and thus me), but is invisible, impersonal, and doesn’t intervene directly in human (or any other) affairs? If I believe in a deity that may as well not exist, do I still “believe in God?” What if I’m one of the ones who believes that God is nature, or God is the energy all around us, or God is love?
I mean, my wife is an observant Reform Jew. She keeps kosher (pretty strictly compared to most RJs I’ve known), observes the holidays, hangs mezuzot in our home…and prays even though she is very doubtful that there’s an anthropomorphic deity listening at the other end of the line. She does it because the feeling of tribal identity, and of connection with ancient tradition, make her feel happy.
Would she qualify as “believing in God?”
