4. 3. Second Temple Sects (516 BCE – 70 CE)

During the Second Temple period, Judaism was not monolithic. The historian Josephus (37–100 CE) identified three major “philosophies”—the Pharisees, Sadducees, and Essenes—plus the Zealots as a political faction. Their disagreements shaped the future of the entire tradition.

Pharisees

The Pharisees (“separated ones”) claimed about 6,000 members at their height but represented the views of the common people. They championed the Oral Torah—the idea that Moses received not only the written text at Sinai but an accompanying oral tradition of interpretation. They believed in the resurrection of the dead, angels, divine providence balanced with free will, and the authority of rabbinic scholars to interpret the law. After the Temple’s destruction in 70 CE, the Pharisaic approach became the foundation of Rabbinic Judaism, the ancestor of all mainstream Jewish denominations today.

Sadducees

The priestly aristocratic party, the Sadducees (probably from “Zadok,” the Davidic-era high priest) rejected the Oral Torah, denied the resurrection of the dead and the existence of angels, and insisted only the Written Torah (Pentateuch) was authoritative. They controlled the Temple cult and the Sanhedrin. With the Temple’s destruction they lost their power base and vanished as a distinct group.

Essenes

An ascetic, semi-monastic sect numbering about 4,000, the Essenes lived communally, practiced celibacy (at least partially), shared property, and observed extreme ritual purity. They are widely identified with the community at Qumran that produced the Dead Sea Scrolls. Their calendar, theology, and apocalypticism diverged sharply from both Pharisees and Sadducees. They disappeared after the Jewish War (66–73 CE).

Zealots

More political faction than theological school, the Zealots advocated armed resistance to Roman rule. Their most radical wing, the Sicarii (“dagger-men”), carried out assassinations. The Zealot revolt culminated in the destruction of the Temple (70 CE) and the fall of Masada (73 CE).

5. 4. Rabbinic Judaism (70 CE – Present)

After the Temple’s destruction, the Pharisaic movement reorganized Jewish life around the synagogue, prayer, and Torah study rather than Temple sacrifice. Rabbi Yohanan ben Zakkai established an academy at Yavneh, and over the following centuries the rabbis compiled the foundational texts that define Judaism to this day:

Rabbinic Judaism is the trunk from which all modern Jewish denominations branch. Every movement—Orthodox, Conservative, Reform, Reconstructionist—defines itself in relation to the rabbinic tradition, whether by strict adherence, selective adaptation, or conscious departure.

Sephardi and Ashkenazi Traditions

By the medieval period, two great cultural-liturgical traditions had crystallized: Sephardi Jews (from the Iberian Peninsula, later dispersed to North Africa, the Ottoman Empire, and the Middle East) and Ashkenazi Jews (from the Rhine Valley, later dominant in Eastern Europe). They share the same core halakhah but differ in liturgical rite (nusach), pronunciation of Hebrew, legal rulings on certain matters, customs (minhagim), and culinary traditions. A third tradition, Mizrachi (Eastern), encompasses communities in Iraq, Iran, Yemen, and Central Asia, often grouped with Sephardim but with distinct customs.

6. 5. Karaite Judaism

Karaite Judaism is the most significant historical schism within the Jewish world. Emerging in 8th-century Mesopotamia (traditionally traced to Anan ben David, c. 760s CE), Karaism rejects the Oral Torah entirely—the Mishnah, Talmud, and all rabbinic authority—and holds that only the Written Torah (Tanakh) is divinely authoritative.

Core Principles

• Sola Scriptura: The Tanakh alone is the source of religious law
• Individual interpretation: Each Jew has the personal responsibility to study Torah and determine its meaning
• Rejection of rabbinic authority: Talmudic rulings are human opinions, not binding law
• Different calendar: Based on observation of the new moon and ripening of barley (aviv), not the fixed rabbinic calendar
• Different Shabbat rules: No lights or fire of any kind on Shabbat (unlike Rabbinic Judaism, which permits pre-lit flames)

Golden Age and Decline

Karaism experienced a Golden Age in the 9th–11th centuries, especially in Jerusalem, where Karaite scholars produced sophisticated biblical commentaries and grammars. The great Rabbanite scholar Saadia Gaon (882–942) considered the Karaites the greatest threat to rabbinic authority and wrote extensively against them, ironically helping sharpen rabbinic theology. At their peak, Karaites may have constituted up to 10% of the Jewish world. Today they number approximately 30,000–50,000, mostly in Israel (centered in Ashdod and Ramla), with about 2,000 in the United States (Daly City, California).

7. 6. Orthodox Judaism: Overview

“Orthodox” is a modern label (first used in the early 19th century) for Jews who maintain that both the Written and Oral Torah were divinely revealed and that halakhah (Jewish law) is binding, eternal, and non-negotiable. Before the Enlightenment, this was simply “Judaism”—the label only became necessary to distinguish traditionalists from the Reform movement.

Core Beliefs

• Torah (Written and Oral) is the direct word of God, revealed to Moses at Sinai
• The 613 commandments (mitzvot) are eternally binding
• Halakhah evolves through interpretation but its principles are unchanging
• The rabbinic tradition (Talmud, codes, responsa) is authoritative
• Strict Shabbat observance, kashrut, family purity laws, daily prayer

Within Orthodoxy, there is enormous internal diversity—from ultra-Orthodox (Haredi) communities that minimize contact with secular society, to Modern Orthodox Jews who fully engage with the modern world while maintaining halakhic observance, to Sephardi Orthodox communities with their own rabbinic authorities and customs.

8. 7. Haredi (Ultra-Orthodox) Judaism

Haredi (“those who tremble” before God, from Isaiah 66:5) Judaism represents the most stringent form of Orthodox observance. Haredi communities emerged in the 19th century as a conscious reaction against the Haskalah (Jewish Enlightenment), the Reform movement, and the secularizing pressures of modernity. Their guiding principle: the Daas Torah—the idea that great Torah scholars possess a divinely guided wisdom that should direct all aspects of life, not just religious matters.

Defining Characteristics

• Strict separation from secular culture (limited internet, television, secular education)
• Distinctive dress: black hats, suits, and white shirts for men; modest dress with hair covering for married women
• Torah study as the supreme value; many men study full-time in kollel (advanced yeshiva for married men)
• Large families (average 6–7 children per family)
• Communal authority of the gadol (great Torah scholar) or rebbe
• Generally anti-Zionist or non-Zionist (with notable exceptions)

The Haredi world divides into two great streams: Hasidic (organized around dynastic rebbes and emphasizing mystical joy) and Lithuanian/Mitnagdic (organized around yeshivot and emphasizing Talmudic scholarship). Though historically bitter rivals, they now cooperate politically and socially against shared external challenges.

Demographics

Haredi Jews are the fastest-growing Jewish demographic, driving 70–80% of total Jewish population growth worldwide. Their fertility rate (6.5–6.7 children per woman) far exceeds all other Jewish groups. In Israel, Haredim constitute roughly 13% of the Jewish population and are projected to reach 25–30% by mid-century. In the U.S., major Haredi concentrations include Brooklyn (Williamsburg, Borough Park, Crown Heights), Lakewood (New Jersey), and Kiryas Joel (New York).

9. 8. Hasidic Judaism & Major Dynasties

Hasidism is a spiritual revival movement founded by Rabbi Israel ben Eliezer, the Baal Shem Tov (“Master of the Good Name,” c. 1700–1760), in Podolia (present-day Ukraine). Against the Talmudic intellectualism of the rabbinical establishment, the Baal Shem Tov taught that every Jew—not just scholars—could achieve communion with God through joyful prayer, song, dance, storytelling, and the cultivation of devekut (clinging to God).

Core Hasidic Concepts

• Devekut: Mystical attachment to God in every action
• Tzaddik/Rebbe: A charismatic righteous leader who serves as intermediary between the community and God
• Hitlahavut: Ecstatic enthusiasm in prayer
• Avodah be-gashmiyut: Serving God through the physical world (eating, drinking, mundane acts elevated to worship)
• Tikkun: Spiritual repair, drawing on Lurianic Kabbalah

Major Hasidic Dynasties

Total worldwide Hasidic population is estimated at ~750,000 (roughly 130,000 households), concentrated in Israel, the New York metropolitan area, London, Antwerp, and Montreal.

10. 9. Mitnagdim (Lithuanian) Judaism

The Mitnagdim (“opponents”) represent the other great stream of Haredi Judaism. Led by the towering figure of the Vilna Gaon (Rabbi Elijah ben Solomon Zalman, 1720–1797), they rejected Hasidism’s mystical enthusiasm, its veneration of the rebbe as intermediary, and its perceived neglect of rigorous Talmud study. The Vilna Gaon even issued a cherem (ban of excommunication) against the Hasidim in 1772.

Core Emphases

• Talmud Torah: Intensive, analytical Talmudic study as the highest religious value
• Mussar: Ethical self-improvement movement (founded by Rabbi Israel Salanter, 1840s)
• Yeshiva system: The great Lithuanian yeshivot (Volozhin, Slabodka, Mir, Ponevezh) became the model for all Haredi yeshivot
• Gadol-centered authority: Deference to the greatest living Talmudic scholars (gedolei Torah)
• Sobriety in worship: Controlled, intellectual prayer style; suspicion of ecstatic or mystical excess

Major Lithuanian Yeshivot Today

Today, the Lithuanian-Mitnagdic stream constitutes roughly 40–45% of the Haredi world, with Hasidim making up the remaining 55–60%. In Israeli politics, Lithuanian Haredim are represented primarily by the Degel HaTorah party (within the United Torah Judaism alliance).

11. 10. Modern Orthodox & Religious Zionism

Modern Orthodoxy accepts the binding nature of halakhah while embracing engagement with the secular world—higher education, professional careers, secular culture, and political participation. Its intellectual foundations were laid by Rabbi Samson Raphael Hirsch (1808–1888) in Germany, with his philosophy of Torah im Derech Eretz (“Torah with the way of the land”), and systematized in America by Rabbi Joseph B. Soloveitchik (1903–1993), the dominant Modern Orthodox thinker of the 20th century.

Key Figures & Institutions

• Yeshiva University (New York): The flagship Modern Orthodox institution, combining Torah study with full university education
• Rabbi Joseph B. Soloveitchik (“The Rav”): Trained a generation of Modern Orthodox rabbis; author of The Lonely Man of Faith
• Open Orthodoxy: A more liberal wing (Rabbi Avi Weiss, Yeshivat Chovevei Torah, Yeshivat Maharat) that ordains women as clergy (“Maharat”); contested by mainstream Modern Orthodoxy

Religious Zionism

A closely related movement, Religious Zionism (Dati Leumi, “National Religious”) synthesizes Orthodox observance with Zionist ideology. Its theological architect was Rabbi Abraham Isaac Kook (1865–1935), first Ashkenazi Chief Rabbi of British Mandatory Palestine, who saw secular Zionism as an unconscious instrument of divine redemption. His son, Rabbi Zvi Yehuda Kook, radicalized this into the settler movement after 1967. The knitted kippah (kippah serugah) is the visual marker of this community.

12. 11. Conservative (Masorti) Judaism

Conservative Judaism (known as Masorti—“traditional”—outside North America) emerged in the mid-19th century as a middle path between Orthodox rigidity and Reform radicalism. Its intellectual roots lie in the Positive-Historical School of Zacharias Frankel (1801–1875) in Germany, who argued that halakhah is binding but has always evolved historically in response to changing circumstances.

Key Principles

• Halakhah is normative but subject to historical development and change through the Conservative Committee on Jewish Law and Standards
• Torah is divinely inspired but not literally dictated word-for-word by God
• Tradition and change: Innovations are permitted when they can be justified within the halakhic system
• Egalitarianism: Women count in a minyan, can be called to the Torah, and have been ordained as rabbis since 1985
• Driving on Shabbat to synagogue was controversially permitted in 1950
• LGBTQ inclusion: Full acceptance of gay and lesbian rabbis since 2006; same-sex marriage liturgy since 2012

Key Institutions

• Jewish Theological Seminary (JTS), New York: The flagship seminary, home to the great scholar Solomon Schechter (1847–1915) and later Abraham Joshua Heschel (1907–1972)
• Ziegler School, Los Angeles
• United Synagogue of Conservative Judaism: Congregational arm
• Camp Ramah: Network of summer camps that shaped generations of Conservative Jews

Demographic Crisis

Once the largest American Jewish denomination (41% of affiliated Jews in 1971), Conservative Judaism has experienced severe decline. By 2020 (Pew Research), only 17% of American Jews identified as Conservative, with members leaving for both Reform (more liberal) and Orthodox (more traditional) communities. The movement retains about 600 congregations in North America.

13. 12. Reform Judaism

Reform Judaism is the largest Jewish denomination in the United States (37% of American Jews, Pew 2020) and the most theologically liberal. It originated in early 19th-century Germany as Jewish intellectuals, newly emancipated by Enlightenment ideals, sought to modernize Jewish worship and belief.

Historical Development

• 1810: Israel Jacobson opens the first Reform temple in Seesen, Germany, introducing organ music, vernacular sermons, and mixed seating
• 1819: Hamburg Temple opens with a reformed prayer book
• 1840s–1870s: German Jewish immigrants bring Reform to America; Rabbi Isaac Mayer Wise founds Hebrew Union College (1875) and the Union of American Hebrew Congregations
• 1885: The Pittsburgh Platform declares Judaism a “progressive religion,” rejects the binding authority of ritual law, and drops hope for a return to Zion
• 1937: The Columbus Platform partially reverses course, reaffirming the value of traditional practices and supporting Zionism
• 1972: Sally Priesand becomes the first woman ordained as a rabbi in America (and in the movement)
• 1983: Patrilineal descent resolution: children of Jewish fathers and non-Jewish mothers accepted as Jewish (a major break with traditional matrilineal descent)
• 1990s–present: Increasing embrace of traditional ritual, Hebrew liturgy, and Israel engagement alongside progressive social positions

Core Principles

• Autonomy of the individual: Each Jew makes informed, personal choices about religious practice
• Ethical monotheism as the enduring core of Judaism
• Torah is divinely inspired but humanly authored—revelation is ongoing
• Halakhah as guidance, not obligation
• Social justice (tikkun olam) as a central religious value
• Full egalitarianism: women, LGBTQ individuals fully included in all aspects of religious life

Key Institutions

• Hebrew Union College–Jewish Institute of Religion (HUC-JIR): Campuses in Cincinnati, New York, Los Angeles, Jerusalem
• Union for Reform Judaism (URJ): ~850 congregations in North America
• Central Conference of American Rabbis (CCAR): Rabbinical body

14. 13. Reconstructionist Judaism

The smallest of the four major American denominations, Reconstructionist Judaism was founded by Rabbi Mordecai Kaplan (1881–1983), who taught at the Conservative movement’s Jewish Theological Seminary for over 50 years before his ideas crystallized into a separate movement.

Kaplan’s Key Ideas

• Judaism as a civilization: Not merely a religion but an evolving civilization encompassing language, culture, art, history, ethics, and folkways alongside theology
• God as a process: Kaplan rejected the supernatural, personal God and defined God as “the Power that makes for salvation”—a naturalistic, process theology
• Halakhah has a vote, not a veto: Tradition should be consulted but cannot override communal moral reasoning
• Chosenness rejected: Kaplan removed references to the “chosen people” concept from the liturgy, viewing it as ethically problematic
• Democratic community: Rabbis guide but the community decides

Institutional History

• 1922: Kaplan’s daughter Judith becomes the first American bat mitzvah
• 1935: Kaplan publishes Judaism as a Civilization
• 1955: The Reconstructionist Rabbinical Association separates from the Conservative movement
• 1968: Reconstructionist Rabbinical College (RRC) founded in Wyncote, Pennsylvania
• 2018: Movement rebrands as Reconstructing Judaism

Today the movement has about 100 congregations and ~1% of American Jews identify as Reconstructionist. Despite its small size, its influence has been disproportionate: Kaplan’s ideas about community, civilization, and bat mitzvah have permeated all non-Orthodox denominations.

15. 14. Other Movements: Renewal, Humanistic, Secular

Jewish Renewal

Founded by Rabbi Zalman Schachter-Shalomi (1924–2014), a Chabad-trained rabbi who became a countercultural spiritual seeker, Jewish Renewal draws on Hasidic mysticism, Kabbalah, meditation, chanting, and ecstatic prayer while embracing egalitarianism, environmentalism, and interfaith dialogue. It is trans-denominational—participants come from Orthodox, Conservative, Reform, and secular backgrounds. The movement’s rabbinical seminary is ALEPH: Alliance for Jewish Renewal. Estimated adherents: a few thousand in organized communities, with broader influence on synagogue worship across denominations.

Humanistic Judaism

Founded in 1963 by Rabbi Sherwin Wine (1928–2007) in Detroit, Humanistic Judaism defines Judaism as the cultural and historical experience of the Jewish people rather than a religion centered on God. Services celebrate Jewish holidays, lifecycle events, and identity without any prayers to or mentions of God. The movement has about 30 congregations in North America and affiliates in 13 countries through the International Institute for Secular Humanistic Judaism.

Secular/Cultural Judaism

A broad, informal category encompassing Jews who identify strongly with Jewish culture, history, ethics, humor, food, and community while practicing little or no religion. By the 2020 Pew survey, 27% of American Jews describe themselves as having “no religion” (“Jews of no religion”). Organizations include the Workmen’s Circle (founded 1900, rooted in Yiddish socialist culture) and the Congress of Secular Jewish Organizations. In Israel, the term hiloni (“secular”) describes roughly 40–45% of the Jewish population.

16. 15. Historical Communities: Samaritans, Beta Israel, Kaifeng

Samaritans

The Samaritans represent arguably the oldest surviving schism in Israelite religion, predating even the Second Temple period. They consider themselves descendants of the ancient Israelite tribes of Ephraim and Manasseh and reject the label “Jewish,” preferring Shamerim (“keepers/observers” of the Torah).

• Scripture: Accept only their own version of the Pentateuch (the Samaritan Torah), which differs in about 6,000 places from the Masoretic text
• Holy site: Mount Gerizim near Nablus (ancient Shechem), not Jerusalem’s Temple Mount
• Temple: Built their own temple on Gerizim (destroyed by John Hyrcanus c. 110 BCE); still sacrifice the Passover lamb there annually
• Reject: All post-Pentateuchal books, the Oral Torah, and rabbinic authority
• Population: About 900 today (split between Holon, Israel, and Kiryat Luza on Mount Gerizim)—the smallest surviving ethno-religious community in the world, recovered from a low of ~150 in the early 20th century

Beta Israel (Ethiopian Jews)

The Beta Israel practiced a pre-rabbinic form of Judaism called Haymanot, based on the Torah and additional texts (the Orit, including Joshua, Judges, and Ruth) in the Ge’ez language. They had no knowledge of the Talmud, Hanukkah, or Purim. Their religious leaders were kessoch (priests), and they maintained a unique monastic tradition with ascetic abba (monks)—unparalleled in the rest of the Jewish world.

• Unique holiday: Sigd—a pilgrimage festival to a mountaintop to renew the covenant with God (recognized as an Israeli national holiday since 2008)
• Aliyah: Operation Moses (1984) and Operation Solomon (1991) airlifted most Beta Israel to Israel; today about 160,000 Ethiopian Jews live in Israel
• Integration challenges: Disputes over the validity of their Judaism led the Israeli Chief Rabbinate to require symbolic conversion and re-marriage under Orthodox law

Kaifeng Jews

A Jewish community existed in Kaifeng, China, from at least the Song Dynasty (c. 960–1127 CE), probably arriving via the Silk Road from Persia. They built a synagogue (last rebuilt 1663, destroyed by flood 1860s) and maintained Jewish practices for centuries while gradually assimilating into Chinese culture. Today a few hundred descendants maintain some awareness of their heritage, but the community no longer practices Judaism in any organized form.

17. 16. Population Distribution

The global Jewish population stands at approximately 15.8 million (2025), with 7.3 million in Israel and 6.3 million in the United States.
