"Judaism: Practice and Belief" was published in 1992 and tested Sanders' thesis in the light of concrete Jewish practices. Sanders argued that there was a "Common Judaism", that is, beliefs and practices common to all Jews, regardless of which religious party they belonged to. After the reign of Salome Alexandra, the Pharisees were a small but very respected party which had a varying amount of influence within Judaism. The main source of power, however, was with the rulers and especially the aristocratic priesthood (Sadducees). Sanders argues that the evidence indicates that the Pharisees did not dictate policy to any of these groups or individuals.
