One of the foundational elements of modern Judaism, tikkun olam (typically translated as repairing the world) is the belief that the wrongs of the world must be solved by humanity, working together for the common good of all. Originating in the early days of the Rabbinic period (around the writing of the Talmuds), tikkun olam has seen added depth through both the lenses of Lurianic Kabbalah (originating with Rabbi Luria in 15th and 16th century Europe) and modern Jewish thought. Throughout all of these developments, though, a key piece has remained: The world is made better by each working towards the good of all. We’ll look at how the idea has changed over the years, how it’s viewed by each of the four major, modern sects (Reform, Reconstructionist, Conservative, and Orthodox) of Judaism, and how it informs the practice of social justice for Unitarian-Universalists.
