Pirkei Avot—often translated as “Ethics of the Fathers”—is the most widely studied rabbinic text in Jewish tradition, yet it is also the most structurally strange book in the Mishnah. Unlike every other tractate, which organizes rules by topic (marriage, Shabbat, civil law), Pirkei Avot is a jumble of sayings linked only by the names of the sages who spoke them. Joseph G. Rosenstein, a distinguished mathematician turned Jewish text scholar, spent years teaching Pirkei Avot Mishnah by Mishnah before realizing that the standard method of study—moving verse by verse in order—causes readers to miss the themes that run underneath the surface. His new book, Pirkei Avot (Ethics of the Fathers): The Big Picture, pulls back to show those patterns.

What if Pirkei Avot has a bigger story to tell? In this episode, Rabbi Marc Katz sits down with Joseph G. Rosenstein to discuss Pirkei Avot (Ethics of the Fathers): The Big Picture (Academic Studies Press, 2026), a fresh approach to one of Judaism’s most beloved collections of rabbinic wisdom.

The 123 teachings of Pirkei Avot often seem to jump from one subject to another: Torah study, ethics, the afterlife, relationships, leadership, and the responsibilities of living a meaningful Jewish life. Rosenstein argues that beneath this seemingly disconnected collection is a larger conceptual framework. Instead of following the mishnayot in their traditional order, he groups them by theme, revealing connections that can be easy to miss when each teaching is studied on its own.

The result is a new way of seeing Pirkei Avot—not as a collection of isolated aphorisms, but as a coherent work that reflects how Judaism was reshaped in the generations following the destruction of the Temple. Rosenstein also turns the book’s ethical teachings into 90 concrete principles for living, organized into 16 themes and accompanied by kavvanot, short meditations designed to help readers put those ideas into practice.

Together, Rosenstein and Katz explore what Pirkei Avot is really trying to teach, why its teachings were assembled the way they were, and what happens when ancient rabbinic wisdom is read not simply as something to study, but as a guide for how to live.
