Judaism is the religion of the Jews. There are an estimated 14 million followers of the Jewish religion around the world. Most of the world's Jews are concentrated in three countries: the United States (six million), Israel (3.7 million), and the Soviet Union (2.5 million). Other nations with significant Jewish populations are France (650 thousand), Great Britain (400 thousand), Canada (300 thousand), Argentina (300 thousand), and Brazil (150 thousand).
Judaism was the first religion based on monotheism, the belief in one God. All of the major Western religions found their roots in Judaism.
A central tenet of Judaism is that God, the Creator of the World, made a special agreement called a covenant (berit in Hebrew) with Abraham, from whom the Jewish people descended. The covenant provided that the Jews would be blessed with God's love and protection if they remained true to God's law and faithfully worshipped Him, and be accountable for sins and transgression against God and His laws. The Jewish People have often been referred to throughout history as the "Chosen People" because of the belief that the Jews were singled out among all of the ancient peoples to receive God's laws and His blessings. According to Judaism, the Jews were chosen to be His servants although God is the universal Creator of all humanity. Jews traditionally do not encourage converts, although converts are accepted after they demonstrate knowledge about the faith and their sincerity in accepting its laws.
The tenets of Judaism include a belief in a coming Messiah (derived from the Hebrew, meaning, "the anointed one") who will unite the Jewish people and lead them under a Kingdom of God on earth and bring peace and justice to all mankind.
While Judaism recognizes an "afterlife," it is principally a "this world" religion. The Creator in Judaistic theology is all-knowing and does not have a corporal form.
Judaism is traditionally decentralized. There is no equivalent to a Pope or other central, international decision-making authority who determines religious dogma or practice. Each Jewish congregation is responsible for its own affairs and is usually, but not always, led by a spiritual leader called a rabbi. Many rabbis are trained in a seminary or university established for the purpose of furthering religious scholarship and teaching. Each of the major groups of Judaism (Orthodox, Conservative, Reform, and Reconstructionist) has its own institution in the United States for training rabbis, and each sect, and for that matter, each congregation, maintains its own practices, traditions, and interpretations of Jewish law.
Jewish worship and study often takes place at a synagogue, and religious services often include prayer and readings from the Torah. Services held in a synagogue are traditionally led by a rabbi and assisted by a cantor, who leads the chanting and songs which accompany prayer. Judaism traditionally emphasizes ethical conduct and the treatment of others "as one would wish to be treated themselves." Thus, the doctrine which does exist through written and oral Jewish law is continually being reinterpreted to respond to modern developments. The major body of Jewish law is found in the Torah, which consists of the Five Books of Moses (also known as the Pentateuch) and which forms the first part of the Old Testament. This law has been supplemented by oral law and interpretations of the law which comprise the Talmud.
There are 613 commandments included in the Torah, which also includes the "Ten Commandments." These 613 commandments govern Jewish law covering such areas as philanthropy, sacrifices, prayer, ritual purity, dietary laws, and observances of the Sabbath and other holy days. The Jewish system of law, also referred to as Halacha, includes a civil and criminal justice system which is followed by observant Jews. Halacha regulates Jewish life, such as marriage and divorce, burial, relationships with non-Jews and education.
