Judaism is an Abrahamic, monotheistic, and widely an ethnic religion. It comprises the collective spiritual, cultural, and legal traditions of the Jewish people, having originated as an organized religion in the Middle East during the Bronze Age. Contemporary Judaism evolved from Yahwism, the cultic religious movement of ancient Israel and Judah, around the 6th/5th century BCE, and is thus considered to be one of the oldest monotheistic religions. Religious Jews regard Judaism as their means of observing the Mosaic covenant, which was established between God and the Israelites, their ancestors. Along with the Samaritanism, Judaism is one of the two oldest Abrahamic religions.
Orthodox Judaism is the collective term for the traditionalist branches of contemporary Judaism. Theologically, it is chiefly defined by regarding the Torah, both Written and Oral, as revealed by God to Moses on Mount Sinai and faithfully transmitted ever since.
There is no established formulation of principles of faith that are recognized by all branches of Judaism. Central authority in Judaism is not vested in any one person or group - although the Sanhedrin, the supreme Jewish religious court, would fulfill this role if it were re-established - but rather in Judaism's sacred writings, laws, and traditions.
Haredi Judaism consists of groups within Orthodox Judaism that are characterized by their strict interpretation of religious sources and their accepted halakha and traditions, in opposition to more accommodating or modern values and practices. Its members are usually referred to as ultra-Orthodox in English; however, the term "ultra-Orthodox" is considered pejorative by many of its adherents, who prefer terms like strictly Orthodox or Haredi. Haredi Jews regard themselves as the most religiously authentic group of Jews, although other movements of Judaism disagree.
The relationships between the various denominations of Judaism are complex and include a range of trends from the conciliatory and welcoming to hostile and antagonistic.
Torah Judaism refers to schools of thought in Judaism perceived to be most adherent to the Torah and mitzvot. The term is often used by Orthodox Jewish groups to refer to their own system of beliefs.
Modern Orthodox Judaism is a movement within Orthodox Judaism that attempts to synthesize Jewish values and the observance of Jewish law with the modern world.
Jewish fundamentalism refers to fundamentalism in the context of Judaism. The term fundamentalism was originally used in reference to Christian fundamentalism, a Protestant movement which emphasizes a belief in biblical literalism. Today, it is commonly used in reference to movements that oppose modernist, liberal, and ecumenical tendencies within society as well as modernist, liberal and ecumenical tendencies within specific religions and it is often coupled with extremist ideologies and/or political movements. The use of this definition is important in a Jewish context because the two movements which are most commonly associated with Jewish fundamentalism, Religious Zionism and Haredi Judaism, stray far from biblical literalism due to the importance of the Oral Law within Judaism. In fact, Karaism, the Jewish movement which is well-known due to its emphasis on biblical literalism, is rarely considered fundamentalist.
Jewish religious movements, sometimes called "denominations", include diverse groups within Judaism which have developed among Jews from ancient times. Today in the west, the most prominent divisions are between traditionalist Orthodox movements and modernist movements such as Reform Judaism originating in late 18th century Europe, Conservative originating in 19th century Europe, and other smaller ones.
Conversion to Judaism is the process by which non-Jews adopt the Jewish religion and become members of the Jewish ethnoreligious community. It thus resembles both conversion to other religions and naturalization. The procedure and requirements for conversion depend on the sponsoring denomination. Furthermore, a conversion done in accordance with one Jewish denomination is not a guarantee of recognition by another denomination. Normally, though not always, the conversions performed by more stringent denominations are recognized by less stringent ones, but not the other way around. A formal conversion is also sometimes undertaken by individuals whose Jewish ancestry is questioned or uncertain, even if they were raised Jewish, but may not actually be considered Jews according to traditional Jewish law.
Norman Lamm was an American Modern Orthodox rabbi, scholar, academic administrator, author, and Jewish community leader. He was the Chancellor of Yeshiva University until he announced his retirement on July 1, 2013.
"Who is a Jew?" is a basic question about Jewish identity and considerations of Jewish self-identification. The question pertains to ideas about Jewish personhood, which have cultural, ethnic, religious, political, genealogical, and personal dimensions. Orthodox Judaism and Conservative Judaism follow Jewish law (Halakha), deeming people to be Jewish if their mothers are Jewish or if they underwent a halakhic conversion. Reform Judaism and Reconstructionist Judaism accept both matrilineal and patrilineal descent as well as conversion. Karaite Judaism predominantly follows patrilineal descent as well as conversion.
Jewish atheism refers to the atheism of people who are ethnically and culturally Jewish. Contrary to popular belief, the term "Jewish atheism" is not a contradiction because Jewish identity encompasses not only religious components, but also ethnic and cultural ones. Jewish law's emphasis on descent through the mother means that even religiously conservative Orthodox Jewish authorities would accept an atheist born to a Jewish mother as fully Jewish.
Schisms among the Jews are cultural as well as religious. They have happened as a product of historical accident, geography, and theology.
Religion in Israel is manifested primarily in Judaism, the ethnic religion of the Jewish people. The State of Israel declares itself as a "Jewish and democratic state" and is the only country in the world with a Jewish-majority population. Other faiths in the country include Islam, Christianity and the religion of the Druze people. Religion plays a central role in national and civil life, and almost all Israeli citizens are automatically registered as members of the state's 14 official religious communities, which exercise control over several matters of personal status, especially marriage. These recognized communities are Orthodox Judaism, Islam, the Druze faith, the Catholic Church, Greek Orthodox Church, Syriac Orthodox Church, Armenian Apostolic Church, Anglicanism, and the Baháʼí Faith.
Early criticism of Judaism and its texts, laws, and practices originated in inter-faith polemics between Christianity and Judaism. Important disputations in the Middle Ages gave rise to widely publicized criticisms. Modern criticisms also reflect the inter-branch Jewish schisms between Orthodox Judaism, Conservative Judaism, and Reform Judaism.
Hashkafa is the Hebrew term for worldview and guiding philosophy, used almost exclusively within Orthodox Judaism. A hashkafa is a perspective that Orthodox Jews adopt that defines many aspects of their lives. Hashkafa thus plays a crucial role in how these interact with the world around them, and influences individual beliefs about secularity, gender roles, and modernity. In that it guides many practical decisions—where to send children to school, what synagogue to attend, and what community to live in—hashkafa works in conjunction with halakha or Jewish law.
The baal teshuva movement is a description of the return of secular Jews to religious Judaism. The term baal teshuva is from the Talmud, literally meaning "master of repentance". The term is used to refer to a worldwide phenomenon among the Jewish people.
Hiloni, plural hilonim, is a social category in Israel, designating the least religious segment among the Jewish public. The other three subgroups on the scale of Jewish-Israeli religiosity are the masortim, "traditional"; datiim, "religious"; and haredim, "ultra-religious" ("ultra-Orthodox"). In the 2018 Israel Central Bureau of Statistics' survey, 43.2% of Jews identified as hiloni.
Masortim is an Israeli Hebrew term for Jews who perceive and define themselves as neither strictly religious (dati) nor secular (hiloni). Their affinity is mainly to mohels and rabbis of Orthodox Judaism, and in 2015 they comprised roughly one-third of the Jewish population in Israel.
