Rabbi Joseph Albo criticised Maimonides’ thirteen articles of faith (‏עיקרים‎). Whilst recognising all of them as true, he would make a difference between fundamental principles (‏עיקרים‎) and secondary beliefs (‏שרשים‎). The former are all those dogmas by which Judaism falls and stands, without which Jewish faith cannot be imagined; the latter are those principles which are actually true, but Judaism can be conceived without them. To the former he counts, e.g., the belief in the existence of God, to the latter the belief that to Him alone prayer is to be offered. For Judaism cannot be conceived without the belief in God’s existence, but could be conceived without the belief that only God is to be prayed to. Albo further finds fault with Maimonides for not having embodied in the Creed the belief in man’s free-will, in the truth of the Biblical account of the miracles, in the Creatio ex nihilo, and the like. To these objections Maimonides would reply, that the articles enumerated by him were all actually fundamental, the question whether Judaism could be imagined without this or that principle being of no importance whatever; and that the dogmas named by Albo as omitted, were implied in the Thirteen Principles. According to Albo there are three fundamental principles (‏עיקרים‎): Existence of God, Revelation, and Reward and Punishment. The first includes four articles (‏שרשים‎): Unity of God, His Incorporeality, Eternity, and Perfection; the second implies three: God’s Omniscience, Divine inspiration, and Divine messengers (prophets); the third only one: Providence. Albo’s criticisms on Maimonides have passed away without effect. The Principles of Faith as formulated by Maimonides have found their way into the daily Prayer-book in prose and poetry, and have since formed an essential element in every text-book of Jewish religion. Modern theologians erroneously quote Albo in favour of rejecting some of the articles, because he speaks of three fundamental principles; but they forget that Albo never rejects any of the thirteen principles; he only insists on making a difference between those which are more and those which are less fundamental.
