תורה שבעל פה, Torah sheba'al peh
Contemporary Jewish polemics use the term “Torah mi-Sinai” to mean a doctrinal belief in the Mosaic authorship of the Torah. The Sages, however, use the term differently, to claim that all of Torah, written and oral, including their very own words, come from Sinai. But is this claim meant to be taken literally?
By erasing the boundaries between Written and Oral Torah, and removing any clear content from God’s revelation of law, Sommer undermines the concept of authoritative halakha that he wishes to refine.
