Knowra Responsa Responsa Responsa are written rabbinic answers to questions of Jewish law and practice. They apply legal sources and interpretation to particular circumstances, forming a major record of Jewish legal reasoning.
She'elot u-Teshuvot : The Hebrew phrase for questions and answers, commonly used for rabbinic legal correspondence and responsa collections. The paired question and ruling give responsa their characteristic form.
Geonim : The heads of the Babylonian Talmudic academies from roughly the seventh through eleventh centuries. Their replies to distant communities established an early, influential responsa tradition.
Shabbat : The Jewish day of rest observed from Friday sunset until Saturday nightfall. Questions about permitted activity on Shabbat recur throughout responsa literature.
Mishneh Torah : Maimonides' comprehensive, systematically arranged code of Jewish law, completed in the twelfth century. Responsa often explain how a general rule in this code applies to a specific case.
Jewish legal history : The history of Jewish law, its interpretation, institutions, and practice across time. Responsa provide a detailed record of legal decisions and changing communal conditions.
Halakha : The collective body of Jewish law governing religious obligations and practice. Responsa interpret halakha in response to concrete cases.
Saadia Gaon : A tenth-century scholar and head of the Sura academy, known for works in Jewish law, philosophy, and biblical translation. His legal correspondence exemplifies responsa from the Geonic period.
Kashrut : The body of Jewish dietary laws governing permitted foods and their preparation. Responsa apply dietary rules to particular ingredients, equipment, and production methods.
Shulchan Aruch : Joseph Caro's sixteenth-century code of Jewish law, later supplemented for Ashkenazi practice by Moses Isserles. Its concise rulings often serve as a baseline for later responsa.
Jewish diaspora : The dispersion of Jewish communities beyond the historic land of Israel and their development across regions. Correspondence linked dispersed communities to rabbinic authorities and shared legal traditions.
