 Verification of divine law. One of the formative factors in Albo’s philosophy was the anti-Christian polemic. For this reason, one of the questions that engages him is the method of distinguishing between the true divine law, meaning the Torah of Moses, and a false religion that also claims to be of divine origin, meaning Christianity. Albo proposes two criteria for distinguishing between the two. Firstly, the true divine law is the one whose beliefs do not contradict any one of the necessary principles of divine law. Secondly, the true divine law provides incontrovertible proof of the credibility of its messenger, who informs the world of the law’s existence and divine origin (treatise 1, chapter 18). An important study on this issue argued that the first point is problematic, because it assumes that philosophy defines the basic beliefs of divine law and thus determines which law is truly divine. This is in opposition to the Averroistic approach, which disallows the use of philosophy for verifying religious matters. The solution for this problem lies in an alternate understanding of the role of philosophy in inter-religious debate. Philosophy does not serve as an affirming mechanism to validate certain beliefs, but only as a negating tool for identifying beliefs that stand in direct conflict with the basic rules of logic. In other words, Albo does not use philosophy to prove the validity of the beliefs of Judaism, but rather to reject Christianity as a false religion in light of its beliefs that stand in contradiction to philosophy (Lasker 1980).
