Halakha in the context of Hebrew Bible

Jewish Christians were the followers of a Jewish religious sect that emerged in Roman Judea during the late Second Temple period, under the Herodian tetrarchy (1st century AD). These Jews believed that Jesus was the prophesied Messiah and they continued their adherence to Jewish law. Jewish Christianity is the historical foundation of Early Christianity, which later developed into Nicene Christianity (which comprises the Roman Catholic, Eastern Orthodox, Oriental Orthodox, and Protestant traditions) and other Christian denominations.

Christianity started with Jewish eschatological expectations, and it developed into the worship of Jesus as the result of his earthly ministry in Galilee and Jerusalem, his crucifixion, and the post-resurrection experiences of his followers. Jewish Christians drifted apart from Second Temple Judaism, and their form of Judaism eventually became a minority strand within mainstream Judaism, as it had almost disappeared by the 5th century AD. Jewish–Christian gospels are lost except for fragments, so there is a considerable amount of uncertainty about the scriptures which were used by this group of Christians.

Comparative law is the study of differences and similarities between the law and legal systems of different countries. More specifically, it involves the study of the different legal systems (or "families") in existence around the world, including common law, civil law, socialist law, Canon law, Jewish Law, Islamic law, Hindu law, and Chinese law. It includes the description and analysis of foreign legal systems, even where no explicit comparison is undertaken. The importance of comparative law has increased enormously in the present age of internationalism and economic globalization.

Religious law includes ethical and moral codes taught by religious traditions. Examples of religiously derived legal codes include Christian canon law (applicable within a wider theological conception in the church, but in modern times distinct from secular state law), Jewish halakha, Islamic sharia, and Hindu law. In some jurisdictions, religious law may apply only to that religion's adherents; in others, it may be enforced by civil authorities for all residents.

In the Ottoman Empire, a millet (Turkish: [millet]; Ottoman Turkish: ملت, Arabic: مِلَّة) was an independent court of law pertaining to "personal law" under which a confessional community (a group abiding by the laws of Muslim sharia, Christian canon law, or Jewish halakha) was allowed to rule itself under its own laws.

Despite frequently being referred to as a "system", before the nineteenth century the organization of what are now retrospectively called millets in the Ottoman Empire was not at all systematic. Rather, non-Muslims were simply given a significant degree of autonomy within their own community, without an overarching structure for the millet as a whole. The notion of distinct millets corresponding to different religious communities within the empire would not emerge until the eighteenth century. Subsequently, the millet system was justified through numerous foundation myths linking it back to the time of Sultan Mehmed the Conqueror (r. 1451–81), although it is now understood that no such system existed in the fifteenth century. Heads of millets, or milletbaşı (Ethnarch), usually had absolute secular and ecclesiastical power over their communities, being answerable only to the Sultan.

A synagogue, or synagog also called a shul or a temple, is a place of worship for Jews and Samaritans. It serves as a house of prayer (with a main sanctuary and sometimes smaller chapels) where Jews attend religious services or ceremonies such as weddings, bar and bat mitzvahs, choir performances, and children's plays. Synagogues often also contain study rooms, social halls, administrative and charitable offices, classrooms for religious and Hebrew studies, and spaces for community gatherings. They frequently display commemorative, historic, or modern artwork alongside items of Jewish historical significance or exhibits about the synagogue itself.

Synagogues are buildings used for Jewish prayer, study, assembly, and reading of the Torah. The Torah (Pentateuch or Five Books of Moses) is traditionally read in its entirety over a period of a year in weekly portions during services, or in some synagogues on a triennial cycle. However, the edifice of a synagogue as such is not essential for holding Jewish worship. Halakha (Jewish law from the Mishnah – the "Oral Torah") states that communal Jewish worship can be carried out wherever a minyan, a group of at least 10 Jewish adult men, is assembled, often (but not necessarily) led by a rabbi. This minyan is the essence of Jewish communal worship, which can also be conducted alone or with fewer than ten people, but that excludes certain prayers as well as communal Torah reading. In terms of its specific ritual and liturgical functions, the synagogue does not replace the long-destroyed Temple in Jerusalem.

A mikveh or Mikvah (Hebrew: מִקְוֶה / מקווה, Modern: mīqve, Tiberian: mīqwe, pl. mikva'ot, mikvot, or (Ashkenazic) mikves, lit. 'a collection') is a bath used for ritual immersion in Judaism to achieve ritual purity.

In Orthodox Judaism, these regulations are steadfastly adhered to; consequently, the mikveh is central to an Orthodox Jewish community. Conservative Judaism also formally holds to the regulations. The existence of a mikveh is considered so important that, according to halacha, a Jewish community is required to construct a kosher mikveh even before building a synagogue, and must go to the extreme of selling Torah scrolls, or even a synagogue if necessary, to provide funding for its construction.

The circumcision of Jesus is an event from the life of Jesus, according to the Gospel of Luke chapter 2, which states:

The eight days after his birth is traditionally observed 1 January. This is in keeping with the Jewish law which holds that males should be circumcised eight days after birth during a Brit milah ceremony, at which they are also given their name. The circumcision of Christ became a very common subject in Christian art from the 10th century onwards, one of numerous events in the Life of Christ to be frequently depicted by artists. It was initially seen only as a scene in larger cycles, but by the Renaissance might be treated as an individual subject for a painting, or form the main subject in an altarpiece.

Biblical law refers to the set of rules found in the Jewish Tanakh, and sometimes also Christian commentaries on these laws in the New Testament. Christianity and Judaism have different approaches to Jewish law.

A rabbi (/ˈræbaɪ/ ; Hebrew: רַבִּי, romanized: rabbī, IPA: [ʁəbːi]) is a spiritual leader or religious teacher in Judaism. A person becomes a rabbi by being ordained by another rabbi—known as semikhah—following a course of study of Jewish history and texts, including the Tanakh, Midrash, Mishnah, Tosefta, Talmud, Halakha, and rabbinic commentaries thereon. The basic form of the rabbi developed between the Second Temple (167 BCE–73 CE)—being heavily influenced by the Pharisees—and Rabbinic periods (70–640 CE), when learned teachers—overlapping with the Tannaim, Amoraim, Savoraim, and early Geonim—assembled to codify Judaism's written and oral laws. The title "rabbi" was first used in the first century CE. In more recent centuries, the duties of a rabbi became increasingly influenced by the duties of the Protestant Christian minister, hence the title "pulpit rabbis." Further, in 19th-century Germany and the United States, rabbinical activities such as delivering sermons, pastoral counseling, and representing the community to the outside all increased in importance.

Within the various Jewish denominations, there are different requirements for rabbinic ordination, and differences in opinion regarding who is recognized as a rabbi. Non-Orthodox movements, including Conservative Judaism, Reform Judaism, Reconstructionist Judaism, and Jewish Renewal, have set their requirements for semikhah based on what they consider halakhic reasons (as in Conservative Judaism) and ethical reasons (as in Reform and Reconstructionist) Judaism).

"Who is a Jew?" (Hebrew: מיהו יהודי, romanized: mihu yehudi, pronounced [ˈmi(h)u je(h)uˈdi]), 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 identity is also commonly defined through ethnicity. Opinion polls have suggested that the majority of modern Jews see being Jewish as predominantly a matter of ancestry and culture, rather than religion.

The Chief Rabbinate of Israel (Hebrew: הָרַבָּנוּת הָרָאשִׁית לְיִשְׂרָאֵל, romanized: Ha-Rabbanut Ha-Rashit Li-Yisra'el) is recognized by Israeli law as the supreme rabbinic authority for Judaism in Israel. It was established in 1921 under the British Mandate and operates on the basis of the Chief Rabbinate of Israel Law, 5740-1980. The Chief Rabbinate Council assists the two Chief Rabbis, who alternate in its presidency. It has legal and administrative authority to organize religious arrangements for Israeli Jews. It also responds to halakhic questions submitted by Jewish public bodies in the Jewish diaspora. The Council sets, guides, and supervises agencies within its authority.

The Chief Rabbinate of Israel consists of two Chief Rabbis: an Ashkenazi rabbi and a Sephardi rabbi; the latter is known as the Rishon leZion. The Chief Rabbis are elected for 10-year terms. The present Sephardi Chief Rabbi is David Yosef, and the Ashkenazi Chief Rabbi is Kalman Ber, both of whom began their terms in 2024.

Orthodox Judaism is a collective term for the traditionalist branches of contemporary Judaism. Theologically, it is chiefly defined by regarding the Torah, both Written and Oral, as literally revealed by God on Mount Sinai and faithfully transmitted ever since.

Orthodox Judaism therefore advocates a strict observance of Jewish law, or halakha, which is to be interpreted and determined only according to traditional methods and in adherence to the continuum of received precedent through the ages. It regards the entire halakhic system as ultimately grounded in immutable revelation, essentially beyond external and historical influence. More than any theoretical issue, obeying the dietary, purity, ethical and other laws of halakha is the hallmark of Orthodoxy. Practicing members are easily distinguishable by their lifestyle, refraining from doing numerous routine actions on the Sabbath and holidays, consuming only kosher food, praying thrice a day, studying the Torah often, donning head covering and tassels for men and modest clothing for women, and so forth. Other key doctrines include belief in a future bodily resurrection of the dead, divine reward and punishment for the righteous and the sinners, the Election of Israel as a people bound by a covenant with God, and an eventual reign of a salvific Messiah who will restore the Temple in Jerusalem and gather the people to Zion.

Haredi Judaism (Hebrew: יהדות חֲרֵדִית, romanized: Yahadut Ḥaredit, IPA: [χaʁeˈdi]) is a branch of Orthodox Judaism that is characterized by its strict interpretation of religious sources and its accepted halakha (Jewish law) and traditions, in opposition to more accommodating values and practices. Its members are often referred to as ultra-Orthodox in English, a term considered pejorative by many of its adherents, who prefer the term strictly Orthodox or Haredi (plural: Haredim). Haredim regard themselves as the most authentic custodians of Jewish religious law and tradition which, in their opinion, is binding and unchangeable. They consider all other expressions of Judaism, including Modern Orthodoxy, as "deviations from God's laws", although other movements of Judaism would disagree.

Some scholars have suggested that Haredi Judaism is a reaction to societal changes, including political emancipation, the Haskalah movement derived from the Enlightenment, acculturation, secularization, religious reform in all its forms from mild to extreme, and the rise of the Jewish national movements. In contrast to Modern Orthodox Jews, Haredim segregate themselves from other parts of society, although some Haredi communities encourage young people to get a professional degree or establish a business. Furthermore, some Haredi groups, like Chabad-Lubavitch, encourage outreach to non-observant and unaffiliated Jews.

Modern Orthodox Judaism (also Modern Orthodox or Modern Orthodoxy) is a movement within Orthodox Judaism that attempts to synthesize Jewish values and the observance of Jewish law with the modern world.

Modern Orthodoxy draws on several teachings and philosophies, and thus assumes various forms. In the United States, and generally in the Western world, Centrist Orthodoxy underpinned by the philosophy of Torah Umadda ("Torah and secular knowledge") is prevalent. In Israel, Modern Orthodoxy is dominated by Religious Zionism; however, although not identical, these movements share many of the same values and many of the same adherents.

Reform Judaism, also known as Liberal Judaism or Progressive Judaism, is a major Jewish denomination that emphasizes the evolving nature of Judaism, the superiority of its ethical aspects to its ceremonial ones, and belief in a continuous revelation which is closely intertwined with human reason and not limited to the theophany at Mount Sinai. A liberal strand of Judaism, it is characterized by little stress on ritual and personal observance, regarding Jewish law as non-binding and the individual Jew as autonomous, and by a great openness to external influences and progressive values.

The origins of Reform Judaism lie in mid-19th-century Germany, where Rabbi Abraham Geiger and his associates formulated its basic principles, attempting to harmonize Jewish tradition with modern sensibilities in the age of emancipation. Understanding Jewish tradition in terms of historical-critical methods and modern philosophy, seeing it as constantly evolving, the early Reform movement sanctioned a conscious adaptation of religious life and the ommission of observances and beliefs considered irrelevant or superstitious. In the public sphere it removed parts of the liturgy pertaining to concepts discarded by it, like bodily resurrection of the dead or the restoration of the sacrifical cult in Jerusalem, and translated much of the prayer from Hebrew to the vernacular German. In the private sphere it condoned and legitimized the widespread abandonment of personal observance of dietary, Sabbath and other ritual laws. European Reform was often conservative, having to co-exist with traditionalist elements within long-established communities. Brought to America by German-born rabbis, the denomination gained prominence in the United States, flourishing from the 1860s to the 1930s in an era known as "Classical Reform". In the American setting, Reform Judaism was free to exercise its ideas without restriction, adopting a universalist approach with little place for Jewish particularism and disposing of most traditional practice. Almost all of the liturgy was in English, converts and male babies were not required to undergo circumcision, and many congregations celebreated the Sabbath also on Sunday. The arrival in America of numerous Eastern European Jewish immigrants, who were generally traditional, led to a renewed interest in observance and collective identity, officially enshrined by the 1937 Columbus platform. Since the 1970s, the movement has adopted a policy of inclusiveness and acceptance, inviting as many as possible to partake in its communities rather than adhering to strict theoretical clarity, becoming extremely diverse. It is strongly identified with progressive and liberal agendas in political and social terms, mainly under the traditional Jewish rubric tikkun olam ("repairing of the world"). Tikkun olam is a central motto of Reform Judaism, and acting in its name is one of the main channels for adherents to express their affiliation. The movement's most significant center is in North America.

Conservative Judaism, also known as Masorti Judaism, is a Jewish religious movement that regards the authority of Jewish law and tradition as emanating primarily from the assent of the people through the generations, more than from divine revelation. It therefore views Jewish law, or Halakha, as both binding and subject to historical development. The Conservative rabbinate employs modern historical-critical research, rather than only traditional methods and sources, and lends great weight to its constituency, when determining its stance on matters of practice. The movement considers its approach as the authentic and most appropriate continuation of Halakhic discourse, maintaining both fealty to received forms and flexibility in their interpretation. It also eschews strict theological definitions, lacking a consensus in matters of faith and allowing great pluralism.

Reconstructionist Judaism is a Jewish movement based on the concepts developed by Rabbi Mordecai Kaplan (1881–1983)—namely, that Judaism is a progressively evolving civilization rather than just a religion. The movement originated as a semi-organized stream within Conservative Judaism, developed between the late 1920s and the 1940s before seceding in 1955, and established a rabbinical college in 1967. Reconstructionist Judaism is recognized by many scholars as one of the five major streams of Judaism in America alongside Orthodox, Conservative, Reform, and Humanistic.

There is substantial theological diversity within the movement. Halakha (Jewish law) is not considered normative or binding, but rather serves as the basis for the ongoing evolution of meaningful Jewish practice. In contrast with the Reform movement's stance during the time he was writing, Kaplan believed that "Jewish life [is] meaningless without Jewish law." One of the planks he wrote for the proto-Reconstructionist Society for the Jewish Renaissance stated, "We accept the halakha, which is rooted in the Talmud, as the norm of Jewish life, availing ourselves, at the same time, of the method implicit therein to interpret and develop the body of Jewish Law by the actual conditions and spiritual needs of modern life." The movement also emphasizes positive views toward modernity. It has an approach to Jewish customs that aims toward communal decision-making through a process of education and distillation of values from traditional Jewish sources.

In its primary meaning, the Hebrew word mitzvah (/ˈmɪtsvə/; Hebrew: מִצְוָה, mīṣvā [mit͡sˈva], plural מִצְווֹת mīṣvōt [mit͡sˈvot]; "commandment") refers to a commandment from God to be performed as a religious duty. Jewish law (halakha) in large part consists of discussion of these commandments. According to religious tradition, there are 613 such commandments.

In its secondary meaning, the word mitzvah refers to a deed performed in order to fulfill such a commandment. As such, the term mitzvah has also come to express an individual act of human kindness in keeping with the law. The expression includes a sense of heartfelt sentiment beyond mere legal duty, as "you shall love your neighbor as yourself" (Leviticus 19:18).

The Shulchan Aruch (Hebrew: שֻׁלְחָן עָרוּך, romanized: šulḥān ʿaruḵ, lit. 'Set Table' [ʃulˈħɔn ʕaˈruχ]), often called "the Code of Jewish Law", is the most widely consulted of the various legal codes in Rabbinic Judaism. It was authored in the city of Safed in what is now Israel by Joseph Karo in 1563 and published in Venice two years later. Together with its commentaries, it is the most widely accepted compilation of halakha or Jewish law ever written.

The halachic rulings in the Shulchan Aruch generally follow Sephardic law and customs, whereas Ashkenazi Jews generally follow the halachic rulings of Moses Isserles, whose glosses to the Shulchan Aruch note where the Sephardic and Ashkenazi customs differ. These glosses are widely referred to as the mappā "tablecloth" to the "Set Table". Almost all published editions of the Shulchan Aruch include this gloss, and the term has come to denote both Karo's work as well as Isserles', with Karo usually referred to as "the Meḥabbēr" (הַמְחַבֵּר, "Author") and Isserles as "the Rema" (a Hebrew acronym of his name).
