Rabbi Professor David Hartman in
Israelis and Jewish Tradition: An Ancient People Debating Its Future
Rabbinic Judaism developed a new paradigm that differed from the dominant biblical model. I believe that had Jews retained the biblical framework alone they would have gone insane. An event-based theology would have driven them into collective manic depression.... What saved them from this manic-depressive relationship with God was a text-centered theology that made God's presence in history a function of the presence of the Torah. As long as we were the carriers of learning and continued to interpret God's word, God was present. In addition to the central significance given to the study of the Torah, the presence of God was felt in all aspects of life because of the expanded range of halakhic obligation.
