To put it crudely, if Christianity is a fantasy religion, then Judaism is a science fiction religion. If the former is individualistic, magical, and salvationist, the latter is collective, technical, and this-worldly.
That said, this Catholic never much cared for fantasy. Trolls, elves, dragons, and wizards all seemed silly to me.
That doesn't sound right. First of all, sacramental Xianity is very collectivist. And second, there's plenty of miracles, supernaturalism, and (while magic is forbidden) qabbalah in Judaism. And as for "this worldly?" This guy seems to have never heard of ha`olam haba'.
