The responsa literature, in which rabbis answer questions about halachah (Jewish law), is a vast treasury reaching back nearly fifteen centuries; Reform rabbis have been writing responsa since the 1800s. In Reading Reform Responsa, Rabbi Mark Washofsky, PhD, presents a deep dive into this literature, boldly arguing that Reform Judaism is indeed a movement fundamentally based on halachah. By inviting and guiding readers to understand Reform responsa with a critical eye, he shows that our movement has always been informed by Jewish law, as well as Reform history. A teacher and mentor of generations of students at Hebrew Union College-Jewish Institute of Religion, Rabbi Washofsky gives us a peek inside his classroom, making Reform responsa-and their history, framing, and context-engaging and accessible for all.
