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.
Religious denomination
Jewish religious movements, sometimes called "denominations" or "branches", include different groups which have developed among Jews from ancient times. Today, the main division is between the Orthodox, Reform, and Conservative lines, with several smaller movements alongside them. This threefold denominational structure is mainly present in the United States, while in Israel the fault lines are between the religious Orthodox and the non-religious.
