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. Other key doctrines include belief in a future resurrection of the dead, divine reward and punishment for the righteous and the sinners, the Election of Israel, and an eventual restoration of the Temple in Jerusalem under the Messiah.
Orthodox Judaism is not a centralized denomination. Relations between its different subgroups are sometimes strained, and the exact limits of Orthodoxy are subject to intense debate. Very roughly, it may be divided between Ultra-Orthodox or "Haredi", which is more conservative and reclusive, and Modern Orthodox Judaism which is relatively open to outer society. Each of those is itself formed of independent streams. They are almost uniformly exclusionist, regarding Orthodoxy as the only authentic form of Judaism and rejecting all competing non-Orthodox philosophies as illegitimate. While adhering to traditional beliefs, the movement is a modern phenomenon. It arose as a result of the breakdown of the autonomous Jewish community since the 18th century, and was much shaped by a conscious struggle against the pressures of secularization and rival alternatives. The strictly observant and theologically aware Orthodox are a definite minority among all Jews, but there are also numerous semi- and non-practicing persons who are officially affiliated or personally identifying with the movement. In total, Orthodox Judaism is the largest Jewish religious group, estimated to have over 2 million practicing adherents and at least an equal number of nominal members or self-identifying supporters.

|Jews and Judaism|
The earliest known mentioning of the term "Orthodox Jews" was made in the Berlinische Monatsschrift in 1795. The word "Orthodox" was borrowed from the general German Enlightenment discourse, and used not to denote a specific religious group, but rather those Jews who opposed Enlightenment. During the early and mid-19th century, with the advent of the progressive movements among German Jews and especially early Reform Judaism, the title "Orthodox" became the epithet of the traditionalists who espoused conservative positions on the issues raised by modernization. They themselves often disliked the alien, Christian, name, preferring titles like "Torah-true" (gesetztreu), and often declared they used it only for the sake of convenience. The Orthodox leader Rabbi Samson Raphael Hirsch referred to "the conviction commonly designated as Orthodox Judaism"; in 1882, when Rabbi Azriel Hildesheimer became convinced that the public understood that his philosophy and Liberal Judaism were radically different, he removed the word "Orthodox" from the name of his Rabbinical Seminary. By the 1920s, the term became common and accepted even in Eastern Europe, and remains as such.
Orthodoxy perceives itself ideologically as the only authentic continuation of Judaism throughout the ages, as it was until the crisis of modernity; in many basic aspects, such as belief in the unadulterated divinity of the Torah or strict adherence to precedent and tradition when ruling in matters of Jewish Law, Orthodoxy is indeed so. Its progressive opponents often shared this view, regarding it as a fossilized remnant of the past and lending credit to their own rivals' ideology. Thus, the term "Orthodox" is often used generically to refer to traditional (even if only at the default sense, of being unrelated to the modernist non-Orthodox movements) synagogues, prayer rites, observances, and so forth.
However, academic research has taken a more nuanced approach, noting that the formation of Orthodox ideology and organizational frameworks was itself a product of modernity. It was brought about by the need to defend and buttress the very concept of tradition, in a world where it was not self-evident anymore. When deep secularization and the dismantlement of communal structures uprooted the old order of Jewish life, traditionalist elements united to form groups which had a distinct self-understanding. This, and all that it entailed, constituted a great change, for the Orthodox had to adapt to the new circumstances no less than anyone else; they developed novel, sometimes radically so, means of action and modes of thought. "Orthodoxization" was a contingent process, drawing from local circumstances and dependent on the extent of threat sensed by its proponents: a sharply-delineated Orthodox identity appeared in Central Europe, in Germany and Hungary, by the 1860s; a less stark one emerged in Eastern Europe during the Interwar period. Among the Jews of the Muslim lands, similar processes on a large scale only occurred around the 1970s, after they immigrated to Israel. Orthodoxy is often described as extremely conservative, ossifying a once-dynamic tradition due to the fear of legitimizing change. While this was not rarely true, its defining feature was not the forbidding of change and "freezing" Jewish heritage in its tracks, but rather the need to adapt to being but one segment of Judaism in a modern world inhospitable to traditional practice. Orthodoxy developed as a variegated "spectrum of reactions" – as termed by Benjamin Brown – involving in many cases much accommodation and leniency. Scholars nowadays, mainly since the mid-1980s, research Orthodox Judaism as a field in itself, examining how the need to confront modernity shaped and changed its beliefs, ideologies, social structure, and halakhic rulings, making it very much distinct from traditional Jewish society.
A definite and conclusive credo was never formulated in Judaism; the very question whether it contains any equivalent of dogma is a matter of intense scholarly controversy. Some researchers attempted to argue that the importance of daily practice and punctilious adherence to Halakha (Jewish law) relegated theoretical issues to an ancillary status. Others dismissed this view entirely, citing the debates in ancient rabbinic sources which castigated various heresies with little reference to observance. However, while lacking a uniform doctrine, Orthodox Judaism is basically united in affirming several core beliefs, disavowal of which is considered major blasphemy. As in other aspects, Orthodox positions reflect the mainstream of traditional Rabbinic Judaism through the ages.
Attempts to codify these beliefs were undertaken by several medieval authorities, including Saadia Gaon and Joseph Albo. Each composed his own creed. Yet the 13 principles expounded by Maimonides in his Commentary on the Mishna, authored in the 1160s, eventually proved the most widely accepted. Various points – for example, Albo listed merely three fundamentals, and did not regard the Messiah as a key tenet – the exact formulation, and the status of disbelievers (whether mere errants or heretics who can no longer be considered part of the People Israel) were contested by many of Maimonides' contemporaries and later sages. Many of their detractors did so from a maximalist position, arguing that the entire corpus of the Torah and the sayings of ancient sages was of canonical stature, not just certain selected beliefs. But in recent centuries, the 13 Principles became standard, and are considered binding and cardinal by Orthodox authorities in a virtually universal manner.
During the Middle Ages, two systems of thought competed for theological primacy, their advocates promoting them as explanatory foundations for observance of the Law. One was the rationalist-philosophic school, which endeavored to present all commandments as serving higher moral and ethical purposes, while the other was the mystical tradition, exemplified in Kabbalah, which assigned each rite with a role in the hidden dimensions of reality. Sheer obedience, without much thought and derived from faithfulness to one's community and ancestry, was believed fit only for the common people, while the educated classes chose either of the two schools. In the modern era, the prestige of both suffered severe blows, and "naive faith" became popular. At a time when excessive contemplation in matters of belief was associated with secularization, luminaries such as Israel Meir Kagan stressed the importance of simple, unsophisticated commitment to the precepts passed down from the Beatified Sages. This is still the standard in the ultra-Orthodox world.
In more open Orthodox circles, attempts were made to formulate philosophies that would confront modern sensibilities. Notable examples are the Hegelian-Kabbalistic theology of Abraham Isaac Kook, who viewed history as progressing toward a Messianic redemption in a dialectic fashion which required the strengthening of heretical forces, or the existentialist thought of Joseph B. Soloveitchik, who was deeply influenced by Neo-Kantian ideals. On the fringes of Orthodoxy, thinkers who were at least (and according to their critics, only) sociologically part of it, ventured toward radical models. These, like the apopathic views of Yeshayahu Leibowitz or the Feminist interpretation of Tamar Ross, had little to no influence on the mainstream.
Orthodox Judaism affirms monotheism – the belief in one God.
The basic tenets of Orthodoxy, drawn from ancient sources like the Talmud as well as later sages, prominently and chiefly include the attributes of God in Judaism: one and indivisible, preceding all creation which he alone brought into being, eternal, omniscient, omnipotent, absolutely incorporeal, and beyond human reason. This basis is evoked in many foundational texts, and is repeated often in the daily prayers, such as in Judaism's creed-like Shema Yisrael: "Hear, O Israel, the Lord is our God, the Lord is One."
Maimonides delineated this understanding of a monotheistic, personal God in the opening six articles of his thirteen. The six concern God's status as the sole creator, his oneness, his impalpability, that he is first and last, that God alone, and no other being, may be worshipped, and that he is omniscient. The supremacy of God of Israel is even applied on non-Jews, who, according to most rabbinic opinions, are banned from the worship of other deities, though they are allowed to "associate" lower divine beings in their faith in God (this notion was mainly used to allow contact with Christians, proving they were not idolaters with whom any business dealings and the like are forbidden.)
The utter imperceptibility of God, considered as beyond human reason and only reachable through what he chose to reveal, was emphasized among others in the ancient ban on making any image of him. Maimonides and virtually all sages in his time and since then also stressed that the creator is incorporeal, lacking "any semblance of a body"; while almost taken for granted since the Middle Ages, Maimonides and his contemporaries noted that anthropomorphic conceptions of God were quite common in their time.
The medieval tension between God's transcendence and equanimity, on the one hand, and his contact and interest in his creation, on the other, found its most popular resolution in the esoteric Kabbalah. The Kabbalists asserted that while God himself is beyond the universe, he progressively unfolds into the created realm via a series of inferior emanations, or Sefirot, each a refraction of the perfect godhead. While widely received, this system also proved contentious and some authorities lambasted it as a threat to God's unity. In modern times it is upheld, at least tacitly, in many traditionalist Orthodox circles, while Modern Orthodoxy mostly ignores it without confronting the notion directly.
The defining doctrine of Orthodox Judaism is the belief that the Torah ("Teaching" or "Law"), both the Written scripture of the Pentateuch and the Oral tradition explicating it, was revealed by God to Moses on Mount Sinai, and that it was transmitted faithfully from Sinai in an unbroken chain ever since. One of the foundational texts of Rabbinic literature is the list opening the Ethics of the Fathers, enumerating the sages who received and passed on the Torah, from Moses through Joshua, the Elders, and Prophets, and then onward until Hillel the Elder and Shammai. This core belief is referred to in classical sources as "The Law/Teaching is from the Heavens" (Torah min HaShamayim).
The basic philosophy of Orthodoxy is that the body of revelation is total and complete; its interpretation and application under new circumstances, required of scholars in every generation, is conceived as an act of inferring and elaborating based on already prescribed methods, not of innovation or addition. One clause in the Jerusalem Talmud asserts that anything which a veteran disciple shall teach was already given at Sinai; and a story in the Babylonian Talmud claims that upon seeing the immensely intricate deduction of future Rabbi Akiva in a vision, Moses himself was at loss, until Akiva proclaimed that everything he teaches was handed over to Moses. The Written and Oral Torah are believed to be intertwined and mutually reliant, for the latter is a source to many of the divine commandments, and the text of the Pentateuch is seen as incomprehensible in itself. God's will may only be surmised by appealing to the Oral Torah revealing the text's allegorical, anagogical, or tropological meaning, not by literalist reading.
Lacunae in received tradition or disagreements between early sages are attributed to disruptions, especially persecutions which caused to that "the Torah was forgotten in Israel" — according to Rabbinic lore, these eventually compelled the legists to write down the Oral Law in the Mishna and Talmud. Yet, the wholeness of the original divine message, and the reliability of those who transmitted it through the ages, are axiomatic. One of the primary intellectual exercises of Torah scholars is to locate discrepancies between Talmudic or other passages, and then demonstrate by complex logical steps (presumably proving each passage referred to a slightly different situation etc.) that there is actually no contradiction. Like other traditional, non-liberal religions, Orthodox Judaism considers revelation as propositional, explicit, verbal and unambiguous, that may serve as a firm source of authority for a set of religious commandments. Modernist understandings of revelation as a subjective, humanly-conditioned experience are rejected by the Orthodox mainstream, though some thinkers at the end of the liberal wing did try to promote such views, finding virtually no acceptance from the establishment.
An important ramification of Torah min HaShamayim in modern times is the reserved, and often totally rejectionist, attitude of Orthodoxy toward the historical-critical method, particularly higher criticism of the Bible. A refusal by rabbis to significantly employ such tools in determining halakhic decisions, and insistence on traditional methods and the need for consensus and continuity with past authorities, is a demarcation line separating the most liberal-leaning Orthodox rabbinic circles from the most right-wing non-Orthodox ones.
While the Sinaitic event is perceived as the supreme and binding act of revelation, it is not the only one. Rabbinic tradition acknowledges matter handed down from the Prophets, as well as announcements from God later on. Secret lore or Kabbalah, allegedly revealed to illustrious figures in the past and passed on through elitist circles, is widely (albeit not universally) esteemed. While not a few prominent Rabbis deplored Kabbalah, and considered it a late forgery, most generally accepted it as legitimate. However, its status in determining normative halakhic decision-making, which is binding for the entire community and not just intended for spiritualists who voluntarily adopt kabbalistic strictures, was always highly controversial. Leading decisors openly applied criteria from Kabbalah in their rulings, while others did so only inadvertently, and many denied it any role in normative Halakha. A closely related mystical phenomenon is the belief in Magidim, supposed dreamlike apparitions or visions, that may inform those who experience them with certain divine knowledge.
Orthodox Judaism now do not include any opinions on eschatology which, in past centuries, were not mainstream views in Judaism. The prophecy of the coming of a Messiah is now central to Orthodox Judaism as it was always the Jewish belief. According to this doctrine, a Messiah will arise from King David's lineage, and will bring with him signs such as the restoration of the Temple, peace, and universal acceptance of God. The Messiah will embark on a quest to gather all Jews to the Holy Land, will proclaim prophethood, and will restore the Davidic Monarchy.
Classical Judaism did incorporate a tradition of belief in the resurrection of the dead.:p. 1 There is scriptural basis for this doctrine, quoted by the Mishnah::p. 24 "All Israelites have a share in the World-to-Come, as it is written: And your people, all of them righteous, Shall possess the land for all time; They are the shoot that I planted, My handiwork in which I glory (Isa 60:21)." The Mishnah also brands as heretics any Jew who rejects the doctrine of resurrection or its origin from the Torah.:p. 25 Those who deny the doctrine are deemed to receive no share in the World-to-Come.:p. 26 The Pharisees believed in both a bodily resurrection and the immortality of the soul. They also believed that acts in this world would effect the state of life in the next world.:p. 61 The Mishnah Sahendrin 10 clarifies that only those who follow the correct theology will have a place in the World to Come.:p. 66
There are other passing references to the afterlife in mishnaic tractates. A particularly important one in the Berakhot informs that the Jewish belief in the afterlife was established long before the compilation of the Mishnah.:p. 70 Biblical tradition categorically mentions Sheol sixty-five times. It is described as an underworld containing the gathering of the dead with their families.:p. 19 Numbers 16:30 states that Korah went into Sheol alive, to describe his death in divine retribution.:p. 20 The deceased who reside in Sheol have a "nebulous" existence and there is no reward or punishment in Sheol, which is represented as a dark and gloomy place. But a distinction is made for kings who are said to be greeted by other kings when entering Sheol.:p.21 Biblical poetry suggests that resurrection from Sheol is possible.:p. 22 Prophetic narratives of resurrection in the Bible have been labelled as external cultural influence by some scholars.:p. 23
The Talmudic discourse expanded on the details of the World to Come. This was to motivate Jewish compliance with their religious codes.:p. 79 In brief, the righteous will be rewarded with a place in Gan Eden, the wicked will be punished in Gehinnom, and the resurrection will take place in the Messianic age. The sequence of these events is unclear.:p. 81 Rabbis have supported the concept of resurrection with plenteous Biblical citations, and have shown it as a sign of God's omnipotence.
A relatively thorough observance of Halakha – rather than any theological and doctrinal matters, which are often subject to diverse opinions – is the concrete demarcation line separating Orthodox Jews from other Jewish movements. As noted both by researchers and communal leaders, the Orthodox subgroups have a sense of commitment towards the Law which is rarely manifest outside the movement, perceiving it as seriously binding.
Law, custom, and tradition
The Halakha, like any jurisprudence, is not a definitive set of rules, but rather an ever-expanding discourse: Its authority is derived from the belief in divine revelation, but interpretation and application are done by the rabbis, who base their mandate on biblical verses such as and thou shalt observe to do according to all that they inform thee. From ancient to modern times, the rabbinic discourse was wrought with controversy (machlokes) and sages disagreeing upon various points of the law. The Talmud itself is mainly a record of such disputes. Traditional belief, maintained by the Orthodox today, regards such disagreement as flowing naturally from the divinity of Jewish Law, which is presumed to potentially contain a solution for any possible predicament. As long as both contesting parties base their arguments according to received hermeneutics and precedents and are driven by sincere faith, both these and those are the words of the Living God (this Talmudic statement is originally attributed to a divine proclamation during a dispute between the House of Hillel and House of Shammai). Majority opinions were accepted and canonized, though many old disagreements remain and new ones appear ceaselessly. This plurality of opinion allows decisors, rabbis tasked with determining the legal stance in subjects without precedent, to weigh between a range of options, based on methods derived from earlier authorities. The most basic form of halakhic discourse is the responsa literature, in which rabbis answered questions directed from commoners or other rabbis, thus setting precedent for the next generations.
The system's oldest and most basic sources are the Mishna and the two Talmuds, to which were added the later commentaries and novellae of the Geonim. Those were followed by the great codes which sought to assemble and standardize the laws, including Isaac Alfasi's Hilchot HaRif, Maimonides' Mishneh Torah, and Jacob ben Asher's Arba'ah Turim. One of the latest and most authoritative codifications is the 1565 Shulchan Aruch, or "Set Table", which gained a canonical status and became almost synonymous, in popular parlance, with the halakhic system itself – though no later authority accepted it in its entirety (for example, all Orthodox Jews don phylacteries in a manner different from the one advocated there), and it was immediately contested or re-interpreted by various commentaries, most prominently the gloss written by Rabbi Moses Isserles named HaMapah. Halakhic literature continued to expand and evolve, with new authoritative guides being compiled and canonized, until the popular works of the 20th century like the Mishnah Berurah.
The most important distinction within Halakha is between all laws derived from God's revelation (d'Oraita); and those enacted by human authorities (d'Rabanan), who are believed traditionally to have been empowered by God to legislate when necessary. The former are either directly understood, derived in various hermeneutical means or attributed to commandments orally handed down to Moses. The authority to pass measures d'Rabanan is itself subject to debate – for one, Maimonides stated that absolute obedience to rabbinic decrees is stipulated by the verse and thou shalt observe, while Nachmanides argued that such severeness is unfounded – though such enactments are accepted as binding, albeit less than the divine commandments. A Talmudic maxim states that, when in doubt regarding a matter d'Oraita, one must rule strenuously, and leniently when it concerns d'Rabanan. Many arguments in halakhic literature revolve over whether any certain detail is derived from the former or the latter source, and under which circumstances. Commandments or prohibitions d'Rabanan, though less stringent than d'Oraita ones, are an equally important facet of Jewish law. They range from the 2nd century BC establishment of Hanukkah, to the bypassing on the Biblical ban on charging interest via the Prozbul, and up to the 1950 standardization of marital rules by the Chief Rabbinate of Israel which forbade polygamy and levirate marriage even in communities which still practiced those.
Apart from these, a third major component buttressing Orthodox practice (and Jewish in general) is local or familial custom, Minhag. The development and acceptance of customs as binding, more than disagreements between decisors, is the main factor accounting for the great diversity in matters of practice across geographic or ethnic lines. While the reverence accorded to Minhag across rabbinic literature is far from uniform – ranging from positions like "a custom may uproot Halakha" to wholly dismissive attitudes – it was generally accepted as binding by the scholars, and more importantly, drew its power from popular adherence and routine.
The most important aspect of Minhag is in the disparities between various Jewish ethnic or communal groups, which also each possess a distinctive tradition of halakhic rulings, stemming from the opinions of local rabbis. Ashkenazim, Sephardim, Teimanim, and others have different prayer rites, somewhat different kosher emphases (since the 12th century at least, it is Ashkenazi custom not to consume legumes in Passover), and numerous other points of distinction. So do, for example, Hasidic Jews and non-Hasidic ones, though both originate from Eastern Europe. The influence of custom even elicited the complaint of scholars who noted that the common masses observe Minhag, yet ignore important divine decrees. Some well-known attributes distinguishing Orthodox Jews, like the donning a head-covering for males at all times or the keeping of separate sinks for dairy and meat products, are customs with little legal basis.
Rabbinic leadership, assigned with implementing and interpreting the already accumulated tradition, changed considerably in recent centuries, marking a major difference between Orthodox and pre-modern Judaism. Since the demise of the Geonim who led the Jewish world up to 1038, Halakha was adjudicated locally, and the final arbiter was mostly the communal Rabbi, the Mara d'Athra (Master of the Area). He was responsible to judicially instruct all members of his community. The emancipation and modern means of transport and communication all jointly made this model untenable. While Orthodox communities, especially the more conservative ones, have rabbis who technically fill this capacity, the public generally follows well-known luminaries whose authority is not limited by geography, and based on reverence and peer pressure more than the now-defunct legal coercion of the old community. These may be either popular chairs of talmudic academies, renowned decisors and, in the Hasidic world, hereditary Rebbes.
Their influence varies considerably: In conservative Orthodox circles, mainly ultra-Orthodox (Haredi) ones, rabbis possess strong authority and exercise their leadership often. Bodies such as the Council of Torah Sages, Council of Torah Luminaries, the Central Rabbinical Congress, and the Orthodox Council of Jerusalem are all considered, at least in theory, as the supreme arbiters in their respective communities. In the more liberal Orthodox sectors, rabbis are revered and consulted, but rarely exert such direct control.
Many Orthodox Jews can be identified by their manner of dress and family lifestyle. Orthodox men and women dress modestly by keeping most of their skin covered. Married women cover their hair, with either scarves (tichel), snoods, hats, or wigs. Orthodox men are expected to wear a ritual fringe called Tzitzit, and a skullcap (kippah). Many men grow beards, and Haredi men wear black hats with a skullcap underneath and suits. Modern Orthodox Jews are sometimes indistinguishable in their dress from general society, although they, too, wear kippahs and tzitzit; additionally, on Shabbat, Modern Orthodox men wear suits (or at least a dress shirt) and dress pants, while women wear fancier dresses or blouses.
Along with these practices, Orthodox Jews practice the laws of negiah, which means touch. Orthodox men and women do not engage in physical contact with those of the opposite sex outside of their spouse, or immediate family members (such as parents, siblings, and children).
Organization and demographics
Orthodox Judaism lacks any central framework or a common, authoritative leadership. It is not a "denomination" in the structural sense, but a variegated spectrum of groups, united in broadly affirming several matters of belief and practice, which also share a consciousness and a common discourse. Individual rabbis may, and often do, gain respect across boundaries, especially recognized decisors, but each community eventually obeys or reveres its own immediate leaders (for example, the ultra-Orthodox world shares a sense of common identity, yet constitutes several large distinct sub-sections, each including hundreds of independent communities with their own rabbis). Apart from this inherent plurality, the limits and boundaries of Orthodoxy are also a matter of great controversy. Indeed, the attempt to offer a definition that would encompass all communities and subgroups challenges scholars. Even the moderately conservative subgroups hotly criticize the more liberal ones for deviation from what they consider as inviolable principles, while strict hard-liners merely dismiss the latter as non-Orthodox. Contentious topics range from the abstract and theoretical, like the attitude to the historical-critical study of scripture, to the mundane and pressing, such as modesty rules for women and girls.
As in any other broad religious movement, there is an intrinsic tension between the ideological and the sociological dimensions of Orthodox Judaism – while the leading elites and intellectuals define adherence in theoretical terms, the masses are inducted via societal, familial, and institutional affiliation. Rank-and-file members may sometimes neither be observant nor fully accept the tenets of faith.
Professors Daniel Elazar and Rela Mintz Geffen, according to calculations made around 1990, assumed in 2012 that there were at least 2,000,000 observant Orthodox Jews worldwide, and at least 2,000,000 additional nominal members and supporters who were identifying with the movement. These figures made Orthodoxy the largest Jewish religious denomination. Originally, Elazar produced an even higher estimate when he considered association by default and assumed higher affiliation rates, reaching a maximum of 5,500,000 that may be considered involved with Orthodoxy.
In the State of Israel, where the total Jewish population is about 6.5 million, 22% of all Jewish respondents to a 2016 PEW survey declared themselves as observant Orthodox (9% Haredim, or "ultra-Orthodox", 13% Datiim, "religious"). 29% described themselves as "traditional", a label largely implying little observance, but identification with Orthodoxy. The second largest Orthodox concentration is in the United States, where a 2013 PEW survey found that 10% of respondents identify as such, in a total Jewish population of at least 5.5 million. 3% were Modern Orthodox, 6% were ultra-Orthodox, and 1% were "other" (Sephardic, liberal Orthodox, etc.) In Britain, of 79,597 households with at least one Jewish member that held synagogue membership in 2016, 66% affiliated with Orthodox synagogues: 53% in "centrist Orthodox", and 13% in "strictly Orthodox" (further 3% were Sephardi, which technically eschews the title "Orthodox").
High birth rates are an important aspect of Orthodox demographics: They are the most reproductive of all Jews, and ultra-Orthodox communities have some of the highest rates in the world, with 6 children per an average household. Non-existent levels of intermarriage (unlike some liberal Jewish denominations, Orthodoxy vehemently opposes the phenomenon) also contribute to their growing share in the world's Jewish population. While American Orthodox are but 10% of all Jews, among children, their share rises immensely: An estimated 61% of Jewish children in New York belong to Orthodox households, 49% to ultra-Orthodox. Similar patterns are observed in Britain and other countries. With present trends sustained, Orthodox Jews are projected to numerically dominate British Jewry by 2031, and American Jewry by 2058. However, their growth is balanced by large numbers of members leaving their communities and observant lifestyle. Among the 2013 PEW respondents, 17% of those under 30 who were raised Orthodox disaffiliated (in earlier generations, this trend was far more prevalent, and 77% of those over 65 left). It is estimated that over 20% of those raised religious Zionist in Israel disaffiliate, and greater numbers adopt a secularized lifestyle and define themselves as "living on the spectrum (of religion)". Loose observance among young adults is common even when they retain formal affiliation.
Orthodox Judaism may be categorized according to varying criteria. The most recognizable sub-group are the Haredim (literally, "anxious" or "fervent"), also known as "ultra-Orthodox", "strictly Orthodox", and the like. They form the most conservative, strict, and self-segregating part of the Orthodox spectrum. Haredim are characterized by a minimal engagement with modern society and culture if not their wholesale rejection, by avowed precedence given to religious values, and by a high degree of rabbinic authority and involvement in daily life. In spite of many differences, Haredi rabbis and communities generally recognize each other as such, and therefore accord respect and legitimacy between them. They are organized in large political structures, mainly Agudath Israel of America and the Israeli United Torah Judaism party. More radical groups include the Central Rabbinical Congress and the Edah HaChareidis. Some Haredim also hold a lukewarm or negative assessment of the more modernist Orthodox. They are easily discerned by their mode of dress, often all black for men and very modest by religious standards for women (including hair covering, long skirts, etc.)
Apart from that, the ultra-Orthodox consist of a large spectrum of communities. They may be roughly classified into three different sub-groups. The first are the Hasidic Jews. The Hasidim originated in 18th-Century Eastern Europe, where they formed as a spiritual revival movement which defied the rabbinical establishment. The threat of modernity turned the movement into a bastion of conservatism and reconciled it with other traditionalist elements. Hasidim espouse a mystical interpretation of religion, with each Hasidic community aligned with a hereditary leader known as Rebbe (who is almost always, though not necessarily, an ordained rabbi). While the spiritualist element of Hasidism declined somewhat through the centuries, the authority of Rebbes is derived from the mystical belief that the holiness of their ancestors is inborn. They exercise tight control over the lives of their followers. Every single one of the several hundreds of independent Hasidic sects (also "courts" or "dynasties"), from large ones with thousands of member households to very small, has its own line of Rebbes. "Courts" often possess unique customs, religious emphases, philosophies, and styles of dress. Hasidim, especially on the Sabbath, don long garments and fur hats, which were once the staple of all Eastern European Jews, but are now associated almost exclusively with them. As of 2016, there were some 130,000 Hasidic households worldwide.
The second Haredi group are the "Litvaks" or "Yeshivish." They originated, in a loose fashion, with the Misnagdim, the opponents of Hasidism, who were mainly concentrated in old Lithuania. The confrontation with the Hasidism bred distinct ideologies and institutions, especially great yeshivas, learning halls, where the study of Torah for its own sake and admiration for the scholars who headed these schools was enshrined. With the advent of secularization, the Misngadim largely abandoned their hostility towards Hasidism. They became defined by affiliation with their yeshivas, and their communities were sometimes composed of alumni of the same institutes. The great prestige ascribed to those as centers of Torah study (after they were rebuilt in Israel and America, bearing the names of original Eastern European yeshivas destroyed in the Holocaust) swept many of a non-Misnagdic background, and the term "Litvak" lost its ethnic connotation. It is in fact granted to all non-Hasidic Haredim of European (Ashkenazi) descent. The "Litvak" sector is led mainly by heads of yeshivas.
The third ultra-Orthodox movement is the Sephardi Haredim, who are particularly identified with the Shas party in Israel and the legacy of Rabbi Ovadia Yosef. Originating in the Mizrahi (Middle Eastern and North African Jews) immigrants to the country who arrived in the 1950's, most of the Sephardi Haredim were educated in Litvak yeshivas, both adopting their educators' mentality and developing a distinct identity in reaction the racism they encountered. Shas arose in the 1980's with the purported aim of reclaiming Sephardi religious legacy, in opposition to Israeli secularism on one hand and the hegemony of European-descended Haredim on the other. While living in strictly observant circles (there are several hundreds of Sephardic-Haredi communal rabbis) they, unlike the insular Hasidim or Litvaks, maintain a strong bond with the lax or nonobservant masses of Israeli Mizrahi society.
Apart from the Haredim, other Orthodox pursue other paths. In the West, especially in the United States, "Modern Orthodoxy", or "Centrist Orthodoxy", is a broad umbrella term for communities which seek an observant lifestyle and traditional theology, but either do not strictly reject the modern world or ascribe a positive role to engagement with it. In America, the Modern Orthodox form a cohesive community and identity group, highly influenced by the legacy of leaders such as Rabbi Joseph B. Soloveitchik, and concentrated around Yeshiva University and institutions like the Orthodox Union or National Council of Young Israel. They affirm a strict obedience to Jewish Law, the centrality of Torah study, and the importance of positive engagement with modern culture. American Modern Orthodoxy underwent growing polarization in recent decades. Both its liberal-leaning wing, that includes organizations such as Edah and Yeshivat Chovevei Torah, and conservative elements, like the Hebrew Theological College, drifted away from the center. Some progressives adopted the name "Open Orthodoxy", intending to enact controversial policies. The "Open Orthodox" were condemned by most Orthodox circles, and decried as heretics by not a few.
In Israel, Religious Zionism represents the largest Orthodox public. While Centrist Orthodoxy's fault-line with the ultra-Orthodox is the attitude to modernity, a fervent adoption of Zionism marks the former. Religious Zionism not only supports the State of Israel, it ascribes an inherent religious value to it; the dominant ideological school, influenced by Rabbi Abraham Isaac Kook's thought, regards the state in messianic terms. Religious Zionism is not a uniform group, and fragmentation between its strict and conservative flank (often named "Chardal", or "National-Haredi") and more liberal and open elements has increased since the 1990s. The National Religious Party, once the single political platform, dissolved, and the common educational system became torn on issues such as gender separation in elementary school or secular studies.
In Europe, "Centrist Orthodoxy" is represented by bodies like the British United Synagogue and the Israelite Central Consistory of France, both the dominant official rabbinates in their respective countries. The laity is often non-observant, retaining formal affiliation due to familial piety or a sense of Jewish identity. Another large non-observant demographic usually considered aligned with Orthodoxy are the Israeli Masortim, or "traditional". This moniker originated with Mizrahi immigrants who were both secularized and reverent toward their communal heritage. However, Mizrahi intellectuals in recent years developed a more reflective, nuanced understanding of this term, eschewing its shallow image and not necessarily agreeing with the formal deference to Orthodox rabbis. Self-conscious Masorti identity is still limited to small, elitist circles.
Even more than in Europe's formal state rabbinates, Orthodox Judaism exerts a powerful, transnational authority through its control of the Chief Rabbinate of Israel. Regulating Jewish marriage, conversion, adoption, and dietary standards in the country, the Chief Rabbinate influences both Israel's population and Jews worldwide.
Until the latter half of the 18th century, Jewish communities in Central and Western Europe were autonomous entities, another estate in the corporate order of society, with their own distinct privileges and obligations. They were led by the affluent wardens' class (parnasim), and judicially subject to rabbinical courts, which ruled in most civil matters. The rabbinical class held the monopoly over education and morals, much like the Christian clergy. Jewish Law was considered normative and enforced upon obstinate transgressors (common sinning was, of course, rebuked but tolerated) with all communal sanctions: imprisonment, taxation, flogging, pillorying, and especially excommunication. Cultural, economic, and social exchange with Christian society was limited and regulated.
This state of affairs came to an end with the rise of the modern, centralized state, which sought to appropriate all authority. The nobility, clergy, urban guilds, and all other corporate estates were gradually stripped of their privileges, inadvertently creating a more equal and secularized society. The Jews were but one of the groups affected: Excommunication was banned, and rabbinic courts lost almost all their jurisdiction. The state, especially since the French Revolution, was more and more inclined to tolerate the Jews only as a religious sect, not as an autonomous entity, and sought to reform and integrate them as useful subjects. Jewish emancipation and equal rights were also discussed. Thus, the Christian (and especially Protestant) differentiation between "religious" and "secular" was applied to Jewish affairs, to which these concepts were traditionally alien. The rabbis were bemused when the state expected them to assume pastoral cares, foregoing their principal role as judiciary. Of secondary importance, much less than the civil and legal transformations, were the ideas of Enlightenment which chafed at the authority of tradition and faith.
By the turn of the century, the weakened rabbinic establishment was facing masses of a new kind of transgressors: They could not be classified nor as tolerable sinners overcome by their urges (khote le-te'avon), neither as schismatics like the Sabbateans or Frankists, against whom all communal sanctions were levied. Their attitudes did not fit the criteria set when faith was a normative and self-evident part of worldly life, but rested on the realities of a new, secularized age. The wardens' class, which wielded most power within the communities, was rapidly acculturating, and often sought to oblige the reforming agenda of the state. Rabbi Elazar Fleckeles, who returned to Prague from the countryside in 1783, recalled that he first faced there "new vices" of principled irreverence towards tradition, rather than "old vices" like gossip or fornication. In Hamburg, Rabbi Raphael Cohen attempted to reinforce traditional norms. Cohen ordered all the men in his community to grow a beard, forbade holding hands with one's wife, and decried women who wore wigs instead of visible headgear to cover their hair; Cohen taxed and otherwise persecuted members of the priestly caste who left the city to marry divorcees, men who appealed to state courts, those who ate food cooked by gentiles and other transgressors. Hamburg's Jews repeatedly appealed to the authorities, which eventually justified Cohen. Yet the unprecedented meddling in his jurisdiction profoundly shocked him, and dealt a blow to the prestige of the rabbinate.
An ideological challenge to rabbinic authority, in contrast to prosaic secularization, appeared in the form of the Haskalah (Jewish Enlightenment) movement which came to the fore in 1782. Hartwig Wessely, Moses Mendelssohn and other maskilim called for a reform of Jewish education, abolition of coercion in matters of conscience, and other modernizing measures. They bypassed rabbinic approval and set themselves, at least implicitly, as a rival intellectual elite. A bitter struggle ensued. Reacting to Mendelssohn's assertion that freedom of conscience must replace communal censure, Rabbi Cohen of Hamburg commented: The very foundation of the Law and commandments rests on coercion, enabling to force obedience and punish the transgressor. Denying it is akin to denying the sun at noon.
However, maskilic-rabbinic rivalry ended rather soon in most Central Europe, for the governments imposed modernization upon their Jewish subjects with regard to neither. Schools replaced traditional Cheders, and standard German began to supplant Judeo-German. Differences between the establishment and the Enlightened became irrelevant, and the former often embraced the views of the latter (now antiquated, as more aggressive modes of acculturation replaced the Haskalah's program). In 1810, when philanthropist Israel Jacobson opened a reformed synagogue in Seesen with a modernized ritual, he encountered little protest.
Hamburg Temple dispute
It was only the foundation of the Hamburg Temple, in 1818, which mobilized the conservative elements. The organizers of the new Hamburg synagogue, who wished to appeal to acculturated Jews with a modernized ritual, openly defied not just the local rabbinic court that ordered them to desist, but published learned tracts which castigated the entire rabbinical elite as hypocritical and obscurant. The moral threat they posed to rabbinic authority, as well as halakhic issues such as having a gentile play an organ on the Sabbath, were combined with severe theological issues. The Temple's revised prayerbook omitted or rephrased petitions for the coming of the Messiah and renewal of sacrifices (post factum, it was considered as the first Reform liturgy). More than anything else, this doctrinal breach alarmed the traditionalists. Dozens of rabbis from across Europe united in support of the Hamburg rabbinic court, banning the major practices enacted there and offering halakhic grounds for forbidding any change in received custom. Most historians concur that the 1818-1821 Hamburg Temple dispute, with its concerted backlash against Reform and the emergence of a self-aware conservative ideology, marks the beginning of Orthodox Judaism.
The leader and organizer of the Orthodox camp during the dispute, and the most influential figure in early Orthodoxy, was Rabbi Moses Sofer of Pressburg, Hungary. Historian Jacob Katz regarded him as the first to fully grasp the realities of the modern age. Sofer understood that what remained of his political clout would soon disappear, and that he largely lost the ability to enforce observance; as Katz wrote, "obedience to Halakha became dependent on recognizing its validity, and this very validity was challenged by those who did not obey." He was also deeply troubled by reports from his native Frankfurt and the arrival from the west of dismissed rabbis, ejected by progressive wardens, or pious families, fearing for the education of their children. These émigrés often became his ardent followers.
Sofer's response to the crisis of traditional Jewish society was unremitting conservatism, canonizing every detail of prevalent norms in the observant community lest any compromise will legitimize the progressives' claim that the law was fluid or redundant. He was unwilling to trade halakhic opinions with those he considered as merely pretending to honor the rules of rabbinic discourse, while intending to undermine the very system. Sofer also awarded customs with absolute validity, regarding them as uniformly equivalent to vows; he warned already in 1793 that even the "custom of ignoramuses" (one known to be rooted solely in a mistake of the common masses) was to be meticulously observed and revered. Sofer was frank and vehement about his conservative stance, stating during the Hamburg dispute that prayers in the vernacular were not particularly problematic, but he forbade them because they constituted an innovation. He succinctly expressed his attitude in a wordplay he loaned from the Talmud: "The new (Chadash, originally meaning new grain) is forbidden by the Torah anywhere." Regarding the new, ideologically-driven sinners, Sofer commented in 1818 that they should have been anathemized and banished from the People Israel like the heretical sects of yore.
Unlike most if not all rabbis in Central Europe, who had little choice but to compromise, Sofer enjoyed unique circumstances. He too had to tread carefully during the 1810s, tolerating a modernized synagogue in Pressburg and other innovations, and his yeshiva was nearly closed by warden Wolf Breisach. But in 1822, three poor (and therefore traditional) members of the community, whose deceased apostate brother bequeathed them a large fortune, rose to the wardens' board. Breisach died soon after, and the Pressburg community became dominated by the conservatives. Sofer also possessed a strong base in the form of his yeshiva, the world's largest at the time, with hundreds of students. And crucially, the large and privileged Hungarian nobility blocked most imperial reforms in the backward country, including those relevant to the Jews. Hungarian Jewry retained its pre-modern character well into the first half of the 19th century, allowing Sofer's disciples to establish a score of new yeshivas, at a time when these institutions were rapidly closing in the west, and a strong rabbinate in the communities which appointed them. A generation later, a self-aware Orthodoxy was already well entrenched in the country. Hungarian Jewry gave rise both to Orthodoxy in general, in a sense of a comprehensive response to modernity, and specifically to the traditionalist, militant Ultra-Orthodoxy.
The 1818-1821 controversy also elicited a very different response, which first arose in its very epicenter. Severe protests did not affect the Temple's congregants, eventually leading the wardens of Hamburg's Jewish community to a comprehensive compromise for the sake of unity. They dismissed the elderly, traditional Chief Dayan Baruch Oser and appointed Isaac Bernays. The latter was a university graduate, clean-shaven and modernized, who could appeal to the acculturated and the young. Bernays signified a new era, and is believed by historians to be the first modern Rabbi, fitting the demands of the emancipation: his contract forbade him to tax, punish or employ coercion, and he lacked any political or judiciary power. He was also forbidden from interfering the Temple's conduct. Though conservative in the principal issues of faith, in aesthetic, cultural and civil matters, Bernays was a reformer and resembled the Temple leaders. He introduced secular studies for children, wore a cassock like a Protestant clergyman, and delivered frequent vernacular sermons. He forbade the spontaneous, informal character of synagogue conduct typical of Ashkenazi tradition, and ordered prayers to be somber and dignified. Bernays' style reunified the Hamburg community by drawing most of the Temple's members back to the main synagogue, having their aesthetic demands (rather than the theological ones, raised by a learned few) met.
The combination of religious conservatism and embrace of modernity in everything else was emulated elsewhere, earning the epithet "Neo-Orthodoxy." Bernays and his like-minded, such as Rabbi Jacob Ettlinger, fully accepted the platform of the moderate Haskalah, which now lost its progressive edge. While old-style traditional life were still quite extant in Germany until the 1840s, rapid secularization and acculturation turned Neo-Orthodoxy into the strict right-wing of German Jewry. It was fully articulated by Bernays' disciples Samson Raphael Hirsch and Azriel Hildesheimer, active in mid-century. Hirsch, a Hamburg native who was ten during the Temple dispute, combined fierce Orthodox dogmatism and militancy against rival interpretations of Judaism, with leniency on many modern issues and an elated embrace of German culture. Neo-Orthodoxy also spread to other parts and Western Europe.
While insisting on strict observance, the movement both tolerated and actively advocated modernization: Formal religious education for girls, virtually unheard of in traditional society, was introduced; modesty and gender separation were relaxed in favour of the prevalent norms of German society, while men went clean-shaven and dressed like their non-Jewish compatriots; and exclusive Torah study virtually disappeared, supplanted with more basic religious studies (while German Bildung was incorporated), which were to provide children with practical halakhic knowledge for life in the secular world. Synagogue ritual was reformed in semblance of prevalent aesthetic conceptions, much like non-Orthodox synagogues though without the ideological undertone, and the liturgy was often abbreviated. Neo-Orthodoxy mostly did not attempt to thoroughly reconcile its conduct and traditional halakhic or moral norms (which, among others, banned Torah study for women). Rather, it adopted compartmentalization, de facto limiting Judaism to the private and religious sphere while yielding to outer society in the public sphere. While conservative Rabbis in Hungary still thought in terms of the now-lost communal autonomy, the Neo-Orthodox acknowledged, at least de facto, the confessionalization of Judaism under emancipation, turning it from an all-encompassing structure defining every aspect of one's life, into a private religious conviction.
Wissenschaft des Judentums
In the late 1830s, modernist pressures in Germany shifted from the secularization debate, progressing even into the "purely religious" sphere of theology and liturgy. A new generation of young, modern university-trained rabbis (many German states already required communal rabbis to possess such education) sought to reconcile Judaism with the historical-critical study of scripture and the dominant philosophies of the day, especially Kant and Hegel. Influenced by the critical "Science of Judaism" (Wissenscahft des Judentums) pioneered by Leopold Zunz, and often in emulation of the Liberal Protestant milieu, they reexamined and undermined beliefs held as sacred in traditional circles, especially the notion of an unbroken chain from Sinai to the Sages. The more radical among the Wissenschaft rabbis, unwilling to either limit critical analysis or its practical application, coalesced around Rabbi Abraham Geiger to form the full-fledged Reform Judaism. Between 1844 and 1846, Geiger organized three rabbinical synods in Braunschweig, Frankfurt and Breslau, to determine how to refashion Judaism in present times.
The Reform conferences were met with uproar by the Orthodox. Warden Hirsch Lehren of Amsterdam and Rabbi Jacob Ettlinger of Altona both organized anti-Reform manifestos, vehemently denouncing the new initiatives, signed by scores of rabbis from Europe and the Middle East. The tone of the undersigned varied considerably along geographic lines: letters from the traditional societies in Eastern Europe and the Ottoman Empire, implored local leaders to petition the authorities and have them ban the movement. Signatories from Central and Western Europe used terms commensurate with the liberal age. All were implored by the petitioners to be brief and accessible; complex halakhic arguments, intended to convinced the rabbinic elite in past generations, were replaced by an appeal to the secularized masses, the new target audience.
The struggle with Wissenschaft criticism profoundly shaped the Orthodox. For centuries, Ashkenazi rabbinic authorities espoused Nahmanides' position that the Talmudic exegesis, which derived laws from the Torah's text by employing complex hermeneutics, was binding d'Oraita. Geiger and others presented exegesis as an arbitrary, illogical process, and consequently defenders of tradition embraced Maimonides' marginalized claim that the Sages merely buttressed already received laws with biblical citations, rather than actually deriving them through exegesis. As Jay Harris commented: An insulated orthodox, or, rather, traditional rabbinate, feeling no pressing need to defend the validity of the Oral Law, could confidently appropriate the vision of most medieval rabbinic scholars; a defencive German Orthodoxy, by contrast, could not... Thus began a shift in understanding that led Orthodox rabbis and historians in the modern period to insist that the entire oral law was revealed by God to Moses at Sinai. 19th-Century Orthodox commentaries, like the one authored by Malbim, invested great effort to amplify the notion that the Oral and Written Law were intertwined and inseparable. Another contended issue was the Second Day of Festivals, condemned by modernists as a rabbinic decree for which the avowed rationale (lack of a permanent calendar) was clearly defunct. Orthodox thinkers devised novel justifications for upholding the Second Day, often more ideological than strictly halakhic.
