Judaism

Jewish practice is structured by halakha (Jewish law), though the degree of observance varies widely across denominations and individuals. [2][3]

Shabbat (the Sabbath) is observed from Friday evening to Saturday evening as a day of rest, worship, and family gathering. Observant Jews refrain from work (as defined by halakhic categories), attend synagogue services, share festive meals, and engage in study and prayer. [2][3]

Daily prayer traditionally includes three services: Shacharit (morning), Mincha (afternoon), and Ma'ariv (evening). The synagogue (also called shul or temple) is the center of communal worship, study, and gathering. Prayer services include the recitation of the Shema, the Amidah (standing prayer), and Torah readings on Shabbat and holidays. [2][3]

Kashrut (dietary laws) governs what foods may be eaten and how they must be prepared. Key principles include the prohibition of pork and shellfish, the separation of meat and dairy, and the requirement that meat come from animals slaughtered according to specific procedures (shechita). [2][3]

Life-cycle rituals include brit milah (circumcision on the eighth day for boys), bar/bat mitzvah (coming of age at 13/12), marriage under a chuppah (canopy), and burial followed by structured mourning periods (shiva, shloshim). [2][3]

Pilgrimage to Jerusalem, particularly to the Western Wall (the last remnant of the Second Temple complex), remains deeply significant. The annual cycle of holidays, including Rosh Hashanah, Yom Kippur, Sukkot, Passover, Shavuot, and Hanukkah, structures Jewish communal and family life. [2][3]

The Hebrew Bible (Tanakh) is the foundational scripture of Judaism, consisting of three sections: Torah (Teaching/Law, the Five Books of Moses), Nevi'im (Prophets), and Ketuvim (Writings). The Torah, Genesis, Exodus, Leviticus, Numbers, and Deuteronomy, is the most authoritative section, traditionally understood as divinely revealed to Moses at Sinai. [2][3]

"In the beginning God created the heaven and the earth.", Genesis 1:1, King James Version, 1611 (public domain). This opening verse establishes the monotheistic creation narrative foundational to Jewish (and later Christian and Islamic) theology. [6][2][3]

The Talmud is the central text of rabbinic Judaism, consisting of the Mishnah (compiled c. 200 CE by Rabbi Judah ha-Nasi) and the Gemara (rabbinic commentary and discussion, compiled c. 500 CE). Two versions exist: the Babylonian Talmud (Talmud Bavli, more authoritative) and the Jerusalem Talmud (Talmud Yerushalmi). The Talmud addresses law, ethics, philosophy, history, and narrative through a distinctive dialectical method. [2][3]

Additional important texts include the Midrash (collections of biblical interpretation), the Zohar (the central text of Kabbalah, Jewish mysticism), Maimonides' Mishneh Torah and Guide for the Perplexed, and the Shulchan Aruch (the standard code of Jewish law compiled by Joseph Karo in the 16th century). The tradition of commentary and interpretation (including Rashi, Tosafot, and later authorities) is itself considered sacred and authoritative. [2][3]

The global Jewish population is estimated at approximately 14 to 15 million, making Judaism one of the smaller major world religions by adherent count but one of the most historically influential. [1][4]

Israel has the largest Jewish population (approximately 6.9 million), followed by the United States (approximately 5.7-7.5 million, depending on the definition used). Significant Jewish communities also exist in France (approximately 450,000), Canada (approximately 390,000), the United Kingdom (approximately 290,000), Argentina (approximately 180,000), Russia, Australia, and Germany. [1][4]

The Holocaust (1941-1945) resulted in the murder of approximately six million Jews, roughly one-third of the world's Jewish population at the time, and devastated Jewish communities across Europe. The establishment of the State of Israel in 1948 created a new center of Jewish life and has been a defining event in modern Jewish history. [2][3]

Within Judaism, denominational affiliation varies by country. In the United States, the largest movements are Reform (approximately 35% of affiliated Jews), Conservative (approximately 18%), and Orthodox (approximately 10%), with many Jews unaffiliated or identifying as "just Jewish". In Israel, the religious landscape is divided between secular, traditional, religious (dati), and ultra-Orthodox (haredi) categories. [2][3][1][4]

Jewish history spans approximately 3,500 years: [2][3]

c. 2000-1800 BCE: Traditional dating of the patriarchs (Abraham, Isaac, Jacob). c. 1300-1200 BCE: Exodus from Egypt and revelation at Sinai (traditional dating; historicity debated). c. 1000 BCE: United monarchy under David and Solomon; First Temple built in Jerusalem. 586 BCE: Babylonian destruction of the First Temple; Babylonian exile begins. 516 BCE: Second Temple completed after return from exile. c. 200 BCE-200 CE: Development of Pharisaic/rabbinic Judaism; composition of the Mishnah. 70 CE: Roman destruction of the Second Temple; beginning of the rabbinic period. c. 200 CE: Mishnah compiled by Rabbi Judah ha-Nasi. c. 500 CE: Babylonian Talmud completed. 1135-1204: Life of Maimonides (Rambam), the most influential medieval Jewish philosopher. 1290-1492: Expulsions from England (1290), France (1394), and Spain (1492). 18th century: Rise of Hasidism in Eastern Europe; beginning of the Haskalah (Jewish Enlightenment). 1897: First Zionist Congress organized by Theodor Herzl. 1941-1945: The Holocaust; six million Jews murdered. 1948: Establishment of the State of Israel. 20th-21st century: Growth of denominational diversity; ongoing Israeli-Palestinian conflict; global diaspora engagement. [2][3][1]

Modern Judaism encompasses several major denominations that differ in their approach to Jewish law, theology, and practice: [2][3]

Orthodox Judaism: Adheres to traditional halakha as binding and divinely ordained. Includes Modern Orthodox (engaged with secular society while maintaining strict observance) and Haredi/Ultra-Orthodox (more insular, with distinctive dress and lifestyle). Hasidic Judaism, a mystically-oriented movement within Orthodoxy, includes groups such as Chabad-Lubavitch, Satmar, and Breslov. [2][3]

Conservative Judaism (Masorti): Seeks to conserve Jewish tradition while allowing for historical-critical scholarship and measured adaptation to modern life. Accepts the binding nature of halakha but permits its evolution through the Committee on Jewish Law and Standards. Predominant in the United States. [2][3]

Reform Judaism (Progressive/Liberal): Emphasizes ethical monotheism, individual autonomy, and adaptation to contemporary life. Views halakha as a guide rather than binding law. Ordains women and, in most branches, welcomes LGBTQ+ members and clergy. The largest denomination in the United States. [2][3]

Reconstructionist Judaism: Founded by Mordecai Kaplan in the 20th century, views Judaism as an evolving religious civilization rather than a supernaturally revealed religion. Emphasizes community, culture, and ethical values. [2][3]

Additional movements include Jewish Renewal (drawing on mystical and meditative traditions) and Humanistic Judaism (secular, non-theistic). [2][3]

The Jewish calendar is lunisolar, with holidays beginning at sunset: [2][3]

Shabbat (weekly): The Sabbath, observed every Friday evening to Saturday evening, is the most frequent Jewish observance. Rosh Hashanah (September-October): The Jewish New Year, beginning a ten-day period of repentance. Marked by the blowing of the shofar (ram's horn). Yom Kippur (September-October): The Day of Atonement, the holiest day in the Jewish calendar. A 25-hour fast devoted to prayer, repentance, and reconciliation. Sukkot (September-October): The Festival of Booths, commemorating the Israelites' wandering in the wilderness. Families build and eat in temporary shelters (sukkot). Hanukkah (November-December): The Festival of Lights, commemorating the rededication of the Second Temple. Celebrated by lighting the menorah over eight nights. Purim (February-March): Celebrates the deliverance of the Jewish people as told in the Book of Esther. Marked by reading the Megillah, costumes, and festive meals. Passover/Pesach (March-April): Commemorates the Exodus from Egypt. The Seder meal, with its structured readings from the Haggadah, is the central ritual. Shavuot (May-June): Celebrates the giving of the Torah at Sinai. Marked by all-night study sessions and dairy foods. Tisha B'Av (July-August): A day of mourning commemorating the destruction of both Temples and other tragedies in Jewish history. [2][3]

Judaism's leadership structures have evolved significantly over its long history: [2][3]

In the biblical period, leadership included patriarchs, judges, kings, and prophets. The priestly class (kohanim) conducted Temple worship, and the Levites assisted in ritual service. After the destruction of the Second Temple in 70 CE, the rabbinate emerged as the primary form of religious leadership. [2][3]

Rabbis serve as teachers, legal authorities, pastoral counselors, and community leaders. In Orthodox Judaism, rabbinical authority is derived from a chain of ordination (semicha) and mastery of halakhic literature. In Conservative, Reform, and Reconstructionist movements, rabbis are trained in seminaries that combine traditional learning with modern scholarship. [2][3]

The cantor (hazzan) leads liturgical music and prayer in synagogue services. In many communities, lay leaders and synagogue boards play significant governance roles. [2][3]

There is no single supreme authority in Judaism, no pope or central governing body. In Israel, the Chief Rabbinate (with Ashkenazi and Sephardi chief rabbis) has authority over certain matters of personal status (marriage, divorce, conversion) but is not universally recognized by all Jewish movements. In the diaspora, rabbinical organizations and denominational bodies provide guidance but not binding authority. [2][3]

Jewish symbolism reflects the tradition's long history and diverse cultural expressions: [2][3]

The Star of David (Magen David): A six-pointed star that became widely associated with Jewish identity from the 17th century onward and appears on the flag of Israel. The Menorah: A seven-branched candelabrum that was a central feature of the ancient Temple and is now the emblem of the State of Israel. The nine-branched Hanukkiah is used during Hanukkah. The Torah scroll: Handwritten on parchment, housed in the synagogue's ark (aron kodesh), and read publicly during services. The Mezuzah: A small case containing a scroll with the Shema, affixed to doorposts of Jewish homes. Tefillin (phylacteries): Small leather boxes containing Torah passages, worn during weekday morning prayers. The Kippah (yarmulke): A head covering worn during prayer and, by many observant Jews, at all times as a sign of reverence. [2][3]

Hebrew calligraphy and the Hebrew language itself carry deep symbolic significance, as the language of scripture, prayer, and, since the revival of Hebrew in the 19th-20th centuries, daily life in Israel. [2][3]

Jewish tradition honors a long lineage of prophets, sages, scholars, and leaders: [2][3]

Biblical figures include Abraham (the first patriarch, with whom God established the covenant), Moses (who received the Torah at Sinai and led the Exodus from Egypt), King David (who established Jerusalem as the capital), and the prophets Isaiah, Jeremiah, and Ezekiel. [2][3]

Rabbinic figures include Hillel and Shammai (1st century BCE-CE, whose debates shaped early rabbinic law), Rabbi Akiva (c. 50-135 CE), and Rabbi Judah ha-Nasi (compiler of the Mishnah). Maimonides (Moses ben Maimon, 1138-1204) was the most influential medieval Jewish philosopher, producing the Mishneh Torah and the Guide for the Perplexed. Rashi (1040-1105) authored the most widely studied commentaries on the Torah and Talmud. [2][3]

The Baal Shem Tov (c. 1700-1760) founded Hasidism, a mystical revival movement in Eastern Europe. Moses Mendelssohn (1729-1786) was a key figure of the Jewish Enlightenment (Haskalah). Theodor Herzl (1860-1904) founded modern political Zionism. [2][3]

Modern figures include Abraham Joshua Heschel (1907-1972), a theologian and civil rights activist; Joseph Soloveitchik (1903-1993), a leading Modern Orthodox thinker; and Elie Wiesel (1928-2016), Holocaust survivor and Nobel laureate. [2][3]

Jewish ethics are grounded in the Torah and the extensive body of rabbinic interpretation that has developed over millennia. [2][3]

The concept of tikkun olam ("repair of the world") has become a central ethical principle in modern Judaism, particularly in Reform and Conservative movements, emphasizing the Jewish responsibility to work toward social justice and the betterment of society. [2][3]

The 613 mitzvot (commandments) encompass both ritual obligations (between humans and God) and ethical obligations (between humans). The latter include requirements of charity (tzedakah, understood as justice rather than mere generosity), honest business dealings, fair treatment of workers, care for the vulnerable, and the pursuit of justice. [2][3]

"Justice, justice shall thou pursue" (Deuteronomy 16:20, KJV, 1611, public domain) is a frequently cited ethical imperative. The rabbinic principle of pikuach nefesh (the preservation of human life) overrides virtually all other commandments, reflecting the supreme value placed on life. [6][2][3]

Jewish medical ethics, business ethics, environmental ethics, and social ethics draw on halakhic reasoning applied to contemporary situations. The tradition of machloket l'shem shamayim ("argument for the sake of heaven") values ethical debate and disagreement as a means of arriving at truth. [2][3]

Jewish teachings on the afterlife are less systematized than those of Christianity or Islam, and views vary significantly across texts, periods, and denominations. [2][3]

The Hebrew Bible contains relatively little explicit teaching about life after death. Early Israelite religion focused primarily on this-worldly concerns, the covenant, the land, and communal well-being. The concept of Sheol appears in some biblical texts as a shadowy underworld where the dead reside, but it is not equivalent to the Christian concept of hell. [2][3]

By the Second Temple period, beliefs in resurrection and an afterlife had developed, particularly among the Pharisees. The Talmud discusses Olam Ha-Ba (the World to Come), Gan Eden (paradise), and Gehinnom (a place of purification, typically understood as temporary rather than eternal). [2][3]

Maimonides included belief in the resurrection of the dead as one of his Thirteen Principles of Faith. However, he and other philosophers also discussed the immortality of the soul in more philosophical terms. [2][3]

Modern Jewish denominations hold varying views. Orthodox Judaism generally affirms belief in resurrection and the World to Come. Reform Judaism tends to emphasize the ethical legacy one leaves rather than literal afterlife beliefs. Conservative Judaism maintains traditional language while allowing for diverse interpretations. Across all movements, Judaism places primary emphasis on how one lives in this world rather than on reward or punishment in the next. [2][3]

Judaism traces its origins to the ancient Israelites of the eastern Mediterranean, with traditional narratives centering on the patriarchs Abraham, Isaac, and Jacob and the revelation of the Torah to Moses at Mount Sinai. [2][3]

Historical scholarship situates the emergence of Israelite religion in the context of ancient Near Eastern cultures during the 2nd millennium BCE. The earliest archaeological evidence of Israelite identity dates to approximately the 13th-12th centuries BCE. The relationship between the biblical narratives and historical events remains a subject of scholarly debate. [2][3]

The First Temple period (c. 1000-586 BCE) saw the establishment of the monarchy under Saul, David, and Solomon, the construction of the Temple in Jerusalem, and the development of prophetic literature. The Babylonian exile (586-538 BCE) following the Temple's destruction was a transformative period that shaped Jewish identity around text, law, and communal practice rather than Temple sacrifice alone. [2][3]

The Second Temple period (516 BCE-70 CE) witnessed the development of diverse Jewish groups including Pharisees, Sadducees, Essenes, and Zealots. The destruction of the Second Temple by Rome in 70 CE ended the sacrificial cult and gave rise to rabbinic Judaism, the form of Judaism that has continued to the present day. [2][3]

The rabbinic period (c. 70-600 CE) produced the Mishnah and Talmud, establishing the legal and interpretive framework that would govern Jewish life for centuries. Subsequent periods of diaspora, persecution, cultural flowering (such as the Golden Age of Spain), and modern emancipation have all shaped the Judaism practiced today. [2][3]
