 Rabbi Joseph Albo, for instance, in "Sefer Ha-Ikkarim" counts three principles of faith, while Maimonides lists thirteen.While some later rabbis have attempted to reconcile the differences, claiming that Maimonides' principles are covered by Albo's much shorter list, alternative lists provided by other medieval rabbinic authorities seem to indicate some level of tolerance for varying theological perspectives.Though to a certain extent incorporated in the liturgy and utilized for purposes of instruction, these formulations of the cardinal tenets of Judaism carried no greater weight than that imparted to them by the fame and scholarship of their respective authors.
