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.
Origins of Rabbinic Judaism
Judaism at this time was divided into antagonistic factions. The main camps were the Pharisees, Saducees, and Zealots, but also included other less influential sects. This led to further unrest, and the 1st century BC and 1st century AD saw a number of charismatic religious leaders, contributing to what would become the Mishnah of Rabbinic Judaism, including Yochanan ben Zakai and Hanina Ben Dosa. The ministry of Jesus, according to the account of the Gospels, falls into this pattern of sectarian "preachers" or "teachers" with devoted "disciples" (derived from the Greek word for "students").
