It would be one thing to self-consciously explore/explicate the “uncrystallized” theological ideas that are so integral to Jewish religious life, bringing to bear one’s favored philosophical outlook. One could appeal to aid from the neo-Kantians, or Wittgenstein, or Levinas, or for that matter Aristotle. One would then need to face a crucial question: how much and in what ways one’s favored way of thinking maps on to that of the Rabbis. It’s quite another to claim, as is the thrust of much medieval philosophical theology, that Biblical and Rabbinic theological ideas are captured, virtually without remainder, by some favored philosophical explication.
