Bruce Chilton and Jacob Neusner study the points of comparisons and contrast between formative Christianity and Judaism. By identifying three categories of authority in each of the two religious worlds, they show how they have both worked in compelling or failing to get someone to do a given action. The arguments are introduced by a general discussion of the founding figures of the two religions, Moses and Jesus, and how their inherent authority distilled itself through the structure of their religious institutions and intellectual thoughts.
