Judaism is the oldest of the monotheistic faiths. It affirms the existence of one God, Yahweh, who entered into covenant with the descendants of Abraham, God's chosen people. Judaism's holy writings reveal how God has been present with them throughout their history. These writings are known as the Torah, specifically the five books of Moses, but most broadly conceived as the Hebrew Scriptures (traditionally called the Old Testament by Christians) and the compilation of oral tradition known as the Talmud (which includes the Mishnah, the oral law).
According to Scripture, the Hebrew patriarch Abraham (20th century? B.C.) founded the faith that would become known as Judaism. He obeyed the call of God to depart northern Mesopotamia and travel to Canaan. God promised to bless his descendants if they remained faithful in worship. Abraham's line descended through Isaac, then Jacob (also called Israel; his descendants came to be called Israelites). According to Scripture, 12 families that descended from Jacob migrated to Egypt, where they were enslaved. They were led out of bondage (13th century? B.C.) by Moses, who united them in the worship of Yahweh. The Hebrews returned to Canaan after a 40-year sojourn in the desert, conquering from the local peoples the ?promised land? that God had provided for them.
The 12 tribes of Israel lived in a covenant association during the period of the judges (1200??1000? B.C.), leaders known for wisdom and heroism. Saul first established a monarchy (r. 1025??1005? B.C.); his successor, David (r. 1005??965? B.C.), unified the land of Israel and made Jerusalem its religious and political center. Under his son, Solomon (r. 968??928? B.C.), a golden era culminated in the building of a temple, replacing the portable sanctuary in use until that time. Following Solomon's death, the kingdom was split into Israel in the north and Judah in the south. Political conflicts resulted in the conquest of Israel by Assyria (721 B.C.) and the defeat of Judah by Babylon (586 B.C.). Jerusalem and its temple were destroyed, and many Judeans were exiled to Babylon.
During the era of the kings, the prophets were active in Israel and Judah. Their writings emphasize faith in Yahweh as God of Israel and of the entire universe, and they warn of the dangers of worshiping other gods. They also cry out for social justice.
The Judeans were permitted to return in 539 B.C. to Judea, where they were ruled as a Persian province. Though temple and cult were restored in Jerusalem, during the exile a new class of religious leaders had emerged?the scribes. They became rivals to the temple hierarchy and would eventually evolve into the party known as the Pharisees.
Persian rule ended when Alexander the Great conquered Palestine in 332 B.C. After his death, rule of Judea alternated between Egypt and Syria. When the Syrian ruler Antiochus IV Epiphanes tried to prevent the practice of Judaism, a revolt was led by the Maccabees (a Jewish family), winning Jewish independence in 128 B.C. The Romans conquered Jerusalem in 63 B.C.
During this period the Sadducees (temple priests) and the Pharisees (teachers of the law in the synagogues) offered different interpretations of Judaism. Smaller groups that emerged were the Essenes, a religious order; the Apocalyptists, who expected divine deliverance led by the Messiah; and the Zealots, who were prepared to fight for national independence. Hellenism also influenced Judaism at this time.
When the Zealots revolted, the Roman armies destroyed Jerusalem and its temple (A.D. 70). The Jews were scattered in the Diaspora (dispersion) and experienced much persecution. Rabbinic Judaism, developed according to Pharisaic practice and centered on Torah and synagogue, became the primary expression of faith. The Scriptures became codified, and the Talmud took shape. In the 12th century Maimonides formulated the influential 13 Articles of Faith, including belief in God, God's oneness and lack of physical or other form, the changelessness of Torah, restoration of the monarchy under the Messiah, and resurrection of the dead.
Two branches of European Judaism developed during the Middle Ages: the Sephardic, based in Spain and with an affinity to Babylonian Jews; and the Ashkenazic, based in Franco-German lands and affiliated with Rome and Palestine. Two forms of Jewish mysticism also arose at this time: medieval Hasidism and attention to the Kabbalah (a mystical interpretation of Scripture).
After a respite during the 18th-century Enlightenment, anti-Semitism again plagued European Jews in the 19th century, sparking the Zionist movement that culminated in the founding of the state of Israel in 1948. The Holocaust of World War II took the lives of more than 6 million Jews.
Jews today continue synagogue worship, which includes readings from the Law and the Prophets and prayers, such as the Shema (Hear, O Israel) and the Amidah (the 18 Benedictions). Religious life is guided by the commandments of the Torah, which include the practice of circumcision and Sabbath observance.
Present-day Judaism has three main expressions: Orthodox, Conservative, and Reform. Reform movements, resulting from the Haskala (Jewish Enlightenment) of the 18th century, began in western Europe but took root in North America. Reform Jews do not hold the oral law (Talmud) to be a divine revelation, and they emphasize ethical and moral teachings. Orthodox Jews follow the traditional faith and practice with great seriousness. They follow a strict kosher diet and keep the Sabbath with care. Conservative Judaism, which developed in the mid-18th century, holds the Talmud to be authoritative and follows most traditional practices, yet tries to make Judaism relevant for each generation, believing that change and tradition can complement each other. Because a Jewish identity is not dependent upon accepting the Torah, a strong secular movement also exists within Jewish life, including atheist and agnostic elements.
In general, Jews do not proselytize, but they do welcome newcomers to their faith.
