Satan
Each sect of Judaism has its own interpretation of Satan's identity. Conservative Judaism generally rejects the Talmudic interpretation of Satan as a metaphor for the "yetzer hara", and regard him as a literal agent of God. Orthodox Judaism, on the other hand, outwardly embraces Talmudic teachings on Satan, and involves Satan in religious life far more inclusively than other sects. Satan is mentioned explicitly in some daily prayers, including during Shacharit and certain post-meal benedictions, as described in Talmud and the Jewish Code of Law. In Reform Judaism, Satan is generally seen in his Talmudic role as a metaphor for the "yetzer hara" and the symbolic representation of innate human qualities such as selfishness.
Pharisees
During the Second Temple era, when Jews were divided into sects, the Pharisees were one sect among many, and partisan. Each sect claimed a monopoly on the truth, and discouraged marriage between members of different sects. Members of different sects did, however, argue with one another over the correctness of their respective interpretations, although there is no significant, reliable record of such debates between sects. After the destruction of the Second Temple, these sectarian divisions ended. The Rabbis avoided the term "Pharisee," perhaps because it was a term more often used by non-Pharisees, but also because the term was explicitly sectarian. The Rabbis claimed leadership over all Jews, and added to the Amidah the "birkat haMinim", a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the wicked," and which is understood as a rejection of sectarians and sectarianism. This shift by no means resolved conflicts over the interpretation of the Torah; rather, it relocated debates between sects to debates within Rabbinic Judaism. The Pharisaic commitment to scholarly debate as a value in and of itself, rather than merely a byproduct of sectarianism, emerged as a defining feature of Rabbinic Judaism.
