The history of Judaism predates the period to which the term itself actually refers, in that Judaism formally applies to the post-Second Temple period, while its antecedents are to be found in the biblical "religion of Israel." The Bible is no longer considered a homogeneous work; the many traditions represented in it demonstrate variance and growth. While the historicity of the patriarchs' existence and of Moses as the giver of all laws is under question, certain dominant themes can be seen developing in this early period that have importance for later Judaism.
Central to these themes is the notion of monotheism, which most scholars believe to have been the outgrowth of a process that began with polytheism, progressed to henotheism (the worship of one god without denying the existence of others), and ended in the belief in a single Lord of the universe, uniquely different from all His creatures. He is compassionate toward His creation, and in turn humans are to love and fear (i.e., stand in awe of) Him. Because God is holy, He demands that His people be holy, righteous, and just, a kingdom of priests to assist in the fulfillment of His designs for humankind and the world.
Israel's chosenness consists of this special designation and the task that accompanies it. God promises the land of Canaan to Israel as their homeland, the place in which the Temple will be built and sacrificial worship of God carried out. The holy days were the Sabbath, Passover, Shavuot, and Sukkoth; and circumcision, dietary laws, and laws pertaining to dress, agriculture, and social justice characterized the structure of the biblical religion. Three types of leaders existed during this period: the priest ( kohen ), who officiated in the Temple and executed the laws; the prophet ( navi ), to whom was revealed God's messages to His people; and the sage ( hacham ), who taught practical wisdom and proper behavior. There was developing already in this early period a belief in the ultimate coming of God's kingdom on earth, a time of peace and justice. To this was added, after the destruction (586 B.C.) of the First Temple and the Babylonian captivity (which many saw as the consequence of idolatry and which may have been responsible for the final stage of the development from polytheism to monotheism), the expectation of national restoration under the leadership of a descendant of the Davidic house, the Messiah.
