There is no established formulation of principles of faith that are recognized by all branches of Judaism. Central authority in Judaism is not vested in any one person or group - although the Sanhedrin, the supreme Jewish religious court, would fulfill this role if it were re-established - but rather in Judaism's sacred writings, laws, and traditions. There are a number of basic principles that were formulated by medieval rabbinic authorities. These are put forth as fundamental underpinnings inherent in the "acceptance and practice of Judaism".
