A rabbi is a spiritual leader or religious teacher in Judaism. One becomes a rabbi by being ordained by another rabbi—known as semikha—following a course of study of Jewish history and texts such as the Talmud. The basic form of the rabbi developed in the Pharisaic and Talmudic eras, when learned teachers assembled to codify Judaism's written and oral laws. The title "rabbi" was first used in the first century CE. In more recent centuries, the duties of a rabbi became increasingly influenced by the duties of the Protestant Christian minister, hence the title "pulpit rabbis." Further, in 19th-century Germany and the United States, rabbinic activities such as sermons, pastoral counseling, and representing the community to the outside all increased in importance.

Judaism is an Abrahamic, monotheistic, ethnic religion that comprises the collective spiritual, cultural, and legal traditions of the Jewish people. Religious Jews regard Judaism as their means of observing the Mosaic covenant, which they believe was established between God and the Jewish people. The religion is considered one of the earliest monotheistic religions.
