Theology is just not important in Judaism, or in any other religion, really. There's no orthodoxy, as you have it in the Catholic Church. No complicated creeds to which everybody must subscribe. No infallible pronouncements by a pope. Nobody can tell Jews what to believe. Within reason, you can believe what you like... We have orthopraxy instead of orthodoxy. Right practice rather then right belief. That's all. You Christians make such a fuss about theology, but it's not important in the way you think. It's just poetry, really, ways of talking about the inexpressible.
