Raavad was thus an opponent to the codification of the Halakha; but he was even more strongly opposed to the construction of a system of dogmas in Judaism, particularly according to the method followed by Maimonides, who often set up the concepts of the Aristotelian philosophy as Jewish theology. For example: Maimonides (in accordance with his philosophical conviction) declared God's incorporeality to be a principle of faith, or, as he formulates it, "whosoever conceives God to be a corporeal being is an apostate". In Raavad's circles a certain mystical anthropomorphistic conception of the Deity was common, and naturally Raavad resented a statement which practically declared his friends to be apostates. He, therefore, appended to Maimonides' formula this brief but emphatic criticism: "Why does he call such persons apostates? Men better and worthier than he have held this view, for which they believe they have found authority in the Scriptures and in a confusing view of the aggadah." While the phrase concerning the aggadah shows that Raavad himself was not a corporealist, he nevertheless opposed Maimonides' elevating incorporeality into a dogma. When Raavad conversely found Maimonides' opinions on the World to Come and the eternity of the world to be heretical, he has no word of vituperation for Maimonides, but merely contented himself with recording his difference of opinion. Thus, the ultra-conservative Talmudist showed himself to be more theologically tolerant than the greatest of the medieval Jewish philosophers.
