In his book Revelation and Authority, the Bible scholar Benjamin Sommer seeks to harmonize the tenets of Judaism with the current academic consensus that Jewish Scripture, and the Pentateuch in particular, were culled together from a number of disparate sources. To do so, Sommer develops a theology of “participatory” revelation, in which prophets don’t simply record God’s word but receive wordless divine communication that they then translate into human language through their own understanding. He uses this theory to explain the historical evolution of Judaism and deal with disturbing biblical teachings without denying that God’s law is in some sense binding. Jon D. Levenson writes in his review:
Professor Sommer brings the whole range of Jewish learning to bear—biblical, rabbinic, and medieval texts, and modern Jewish theologians, not to mention the occasional ḥasidic rebbe. But the book is not only a learned study: it is also a rarity in the Jewish world—a theologically serious book written by a Jew who is not only a scholar but also a practitioner of Judaism. Unlike so many in Jewish studies—especially Jewish scholars specializing in biblical studies—Sommer does not hide behind historicism but instead addresses the existential relevance of his material without embarrassment. He engages in what Christians tend to call “systematic” or “constructive” theology and does so, moreover, in a way that seeks to be both faithful to the pre-modern tradition and responsible to the methods and findings of modern critical thought.
Yet, to Levenson, there are serious flaws in the book’s arguments, perhaps most crucially in its claim that revelation is not limited to Moses but is available to many “human beings who respond to the revelation at Sinai” and even to all Israelites:
To me, and again locating ourselves only within the cultural universe of biblical Israel in general and the Pentateuch in particular, this move from the figure of Moses to human beings in general represents a dangerous slippage. For it drastically underestimates the unique and unparalleled role of Moses as the chosen intermediary of divine revelation. Here, an analogy with glossolalia, the speaking-in-tongues practiced by some charismatic Christians, might be helpful. The person with the gift of tongues makes sounds that ordinary people cannot decode; in order for the sounds to be comprehended, an interpreter must translate them. But that ability to interpret tongues is itself thought to be a spiritual gift. It is not a natural human endowment, and therefore it is not a strong analogy to the composition of biblical texts as modern historical critics tend to understand it—that is, as a purely human process.
Moses does indeed participate in the process of revelation, but only because of a gift with which God has graced him. He is the unique mediator of the laws; he is not their formulator. The radical, principled difference between the biblical and the historical-critical understandings of the process of composition must not be minimized. The former makes unapologetic use of notions of supernatural endowments that the latter excludes from the conversation a priori. To me, Sommer seems so eager to validate the participation of humans in the process of revelation that he fails to do justice to the special subcategory of humans called prophets and to the unique and unparalleled role among among them that much biblical and post-biblical tradition ascribes to Moses.
