Judaism was founded around 2000 B.C.E. when Abraham reportedly made a covenant with God. There are three main divisions of Judaism. They are Orthodox, Conservative, and Reform Jews. Orthodox Jews are people who must follow all Jewish laws and traditions. Conservative Jews recognize law and tradition, but are open to new ideas.Reform Jews allow each generation to accept, reject, and modify traditions.
The synagogue is the house of worship and the center of Jewish education and communal affairs. Rabbi literally means teacher in Hebrew. The Rabbi is the spiritual leader, teacher, and interpreter of the Jewish law. Each congregation chooses it's own rabbi. There is no world leader or ruling body with authority over practice. Judaism is a monotheistic religion.
