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.
Sadducees
The Sadducees (; Hebrew: "Ṣĕdûqîm") were a sect or group of Jews that was active in Judea during the Second Temple period, starting from the second century BCE through the destruction of the Temple in 70 CE. The sect was identified by Josephus with the upper social and economic echelon of Judean society. As a whole, the sect fulfilled various political, social, and religious roles, including maintaining the Temple. The Sadducees are often compared to other contemporaneous sects, including the Pharisees and the Essenes. Their sect is believed to have become extinct some time after the destruction of Herod's Temple in Jerusalem in 70 CE, but it has been speculated that the later Karaites may have had some roots in—or connections with—Sadducaic views.
