The central religious belief of Judaism is that there is only one God. Monotheism was uncommon at the time Judaism was born, but according to Jewish tradition, God himself revealed it to Abraham, the ancestor of the Jewish people. Beginning with Abraham, God has always taken special care of the Hebrews (who would later become the Jews). After rescuing them from slavery in Egypt, God revealed the Ten Commandments to Moses, and many more religious and ethical guidelines in the Torah ("the Law"). Many of the guidelines (mitzvah) emphasized ritual purity and the importance of remaining set apart from the surrounding polytheistic cultures.
Aside from its staunch monotheism, Judaism has few essential beliefs.
Jewish identity arises primarily from belonging to an ancient people
and upholding its traditions. Dogma, while important, is secondary.
Although the medieval thinker Rabbi Maimonides once enumerated "13 Articles of Faith,"
many Jews do not accept all these, and Jewish beliefs vary widely on
theological matters such as human nature and the afterlife.
Divisions within Judaism, known as movements, have developed in modern times as varying responses to secularism and modernity. Orthodox Judaism is the most conservative group, retaining nearly all traditional rituals and practices. At the opposite end of the spectrum, Reform Jews retain their Jewish identity and some traditions but take a liberal approach to many Jewish beliefs and practices. Conservative Judaism lies in the middle of the spectrum, taking a moderate approach in its application of Judaism to the modern world.
Judaism Beliefs
Judaism has no official creed or universal doctrinal requirements for membership. In general, a person can be considered "Jewish" whether he adheres to a complete system of beliefs about God and the afterlife, holds only a few simple beliefs that give meaning to ritual, or even (at least in liberal Judaism) does not believe in God at all.
This diversity in Jewish belief arises in part because actions (good deeds and the mitzvot), not beliefs, are the most important aspect of Jewish religious life. In addition, the term "Jewish" can be used to describe a race and a culture rather than a religion, so some who identify themselves as Jewish may have little interest in the beliefs and practices associated with the religion of Judaism.
Nevertheless, the Torah and Talmud have a great deal to say about God, humanity, and the meaning of life, and Jewish history has seen significant theological and mystical inquiry into religious concepts. These beliefs are of great significance not only for Judaism itself, but also for their direct influence on Christianity and Islam, currently the two largest religions in the world.
The great 12th-century Rabbi Maimonides put together "13 Articles of Faith" that he believed every Jew ought to adhere to. These have been widely accepted as a proper expression of the Jewish faith and they still appear in Jewish prayer books today. So while it is not necessary to believe all of these articles to be Jewish (and in fact many Jews would likely question one or more of the articles) they serve as a good general summary of religious Judaism. The 13 Articles of the Jewish Faith proposed by Maimonides are these: God exists, God is one and unique, God is incorporeal, God is eternal, Prayer is to God only, The prophets spoke truth, Moses was the greatest of the prophets, The Written and Oral Torah were given to Moses, There will be no other Torah, God knows the thoughts and deeds of men, God will reward the good and punish the wicked, The Messiah will come, and The dead will be resurrected.A fundamental Jewish belief about human beings is that they are created in the image of God. This does not mean that we look like God, for God is incorporeal. The general rabbinical interpretation of this concept is that humans have the ability to reason. The Torah and Talmud alike focus on the purpose of earthly life, which is to fulfill one's duties to God and one's fellow man. Succeeding at this brings reward, failing at it brings punishment. Whether rewards and punishments continue after death, or whether anything at all happens after death, is not as important.
In Judaism, the eternal destination for the righteous is Gan Eden (the Garden of Eden). It is generally described as a place of great joy and peace. Talmudic imagery includes: sitting at golden banquet tables (Babylonian Talmud, tractate Taanit 25a) or at stools of gold (Babylonian Talmud, tractate Ketubot 77b), enjoying lavish banquets (Babylonian Talmud, tractate Baba Batra 75a), or celebrating the Sabbath, enjoying sunshine and intercourse (Babylonian Talmud, tractate Berachot 57b). The Jewish concept of the afterlife for the wicked is less developed. Known as Gehinnom (Gehenna in Yiddish) or Sheo'l, it has its foundations in the dark pit described in the Torah (see above) and an actual place where a pagan cult conducted rituals included burning children. The messianic age is a period in human history that will be initiated when the messiah comes. At that time the righteous dead will be resurrected, but the wicked will not. The messianic age will be a time of peace and the restoration of the land and organizations of Israel.
Differences between Jewish denominations, which are more commonly known as "movements," reflect varying responses to changing times and cultures. The historical Jewish movements (Pharisses, Sadduccees, and Essenes) were responses to the Roman rule of Israel, while the major modern movements (Reform, Orthodox, and Conservative) are responses to the modern, secular culture of Europe and America.
Orthodox Judaism is the most traditional expression of modern Judaism. Orthodox Jews believe the entire Torah - including "Written," the the Pentateuch, and "Oral," the Talmud) was given to Moses by God at Sinai and remains authoritative for modern life in its entirety. According to a 1990 nationwide survey, 7 percent of American Jews are Orthodox.
Reform Judaism is the most liberal expression of Judaism. In America, Reform Judaism is organized under the Union for Reform Judaism (known as the Union of American Hebrew Congregations until 2003), whose mission is "to create and sustain vibrant Jewish congregations wherever Reform Jews live." About 1.5 million Jews in 900 synagogues are members of the Union for Reform Judaism.
Conservative Judaism may be said to be a moderate position between Orthodox and Reform Judaism. It seeks to conserve the traditional elements of Judaism, while allowing for modernization to a less radical extent than Reform Judaism. The teachings of Zacharias Frankel (1801-75) form the foundation of Conservative Judaism.
Hasidic (or Chasidic) Judaism arose in 12th-century Germany as a mystical movement emphasizing asceticism and experience born out of love and humility before God. The austere religious life of these early Hasids ("pious ones") is documented in the Sefer Hasidim ("Book of the Pious"). The modern Hasidic movement was founded in Poland in the 18th century by Israel ben Eliezer, more commonly known as the Baal Shem Tov ("Master of the Good Name") or "the Besht" (an acronym for Baal Shem Tov).
The mystical form of Judaism is Kabbalah. Broadly speaking, Kabbalah refers to Jewish mysticism dating back to the time of the second Temple. For many years a carefully guarded oral tradition, it became systematized and dispersed in the Middle Ages. The kabbalistic viewpoint was expressed most importantly in the Yalkut Re'uveni by Reuben Hoeshke in 1660, but also made its way into prayer books, popular customs and ethics. The focus of the Kabbalah is the simultaneous transcendence and immanence of God, with the latter described in terms of the sefirot, or attributes of God.
