Why Does God Hate Yeast?

Rabbinic Perspectives: Conversations for Our TimeS

Rabbi Robert Levy
Emeritus Temple Beth Emeth, Ann Arbor MI; Chair, Rabbis and Cantors Retirement Plan; Faculty, École Rabbinique de Paris

This session in our new series will explore the issues surrounding the core accepted value of Pesach: the prohibition against consuming foods and drinks produced through leavening. These consumables are often synonymous with bread products but also include beer. The common element is yeast, which God does not appreciate as we humans do.

The core text for our discussion will be Exodus 12. Rashi calls Exodus 12 the Jewish starting point for the Torah, with the Book of Genesis and Exodus 1-11 being, in a sense, a prologue. Yet both Genesis and Exodus describe a universe radically different (and two steps removed) from the worldview of (1) classical rabbinic Judaism and (2) the modern world as we understand it.

God does hate yeast, but the real question is: What is the nature of the world that God loves as described in the Torah?
