Title: Modern Orthodox Judaism
Content:  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 secular, 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.

Content:  Judaism and those who reject the Covenant forfeit their share in the World to Come. Establishing the core tenets of Judaism in the modern era is even more difficult, given the number and diversity of the contemporary Jewish denominations. Even if to restrict the problem to the most influential intellectual trends of the nineteenth and twentieth century, the matter remains complicated. Thus for instance, Joseph Soloveitchik's (associated with the Modern Orthodox movement) answer to modernity is constituted upon the identification of Judaism with following the halakha whereas its ultimate goal is to bring the holiness down to the world. Mordecai Kaplan, the founder of the Reconstructionist Judaism, abandons

Content:  Because Orthodox Judaism is so deeply entrenched in its tradition, the question of how to incorporate and adapt to modernity, in terms modern of culture and thought, lies at the center of disagreements between Orthodox groups. Modern Orthodox Jews view their interactions with the world around them and the development of society as an integral part of their theology. They do not view modernity as a threat; they embrace it. Modern Orthodox Jews are likely to view themselves as citizens of the modern world. Great Jewish thinkers such as Rabbi Samson Raphael Hirsch and Rabbi Joseph Soloveitchik sometimes integrated modern thought into their worldview. Hasidism is generally opposed to the idea of integrating modern ideas and culture into their well-established theological thought. Hasidic Jews do not wear modern clothing, while Modern Orthodox Jews find no objection to it, provided that the clothing is modest.

Content:  Various highly differing views (or non views) – ranging from traditionalist to revisionist – are thus offered under the banner of "Modern Orthodoxy". In fact, even among its leadership, there is limited agreement "on the philosophical parameters of modern Orthodoxy". The boundaries here, with respect to Haredi and Conservative Judaism, have therefore become increasingly indistinct. At the same time, some elements of Haredi Judaism appear to be more receptive to messages that have traditionally been part of the Modern-Orthodox agenda. Similarly, at Modern Orthodoxy's left, many appear to align with more traditional elements of Conservative Judaism. In discussing "Modern Orthodoxy", it is thus also important to clarify its position with reference to other movements in Judaism: see Comparison with other movements below. Further, given this wide range of views, some see the possibility that, in fact, "[t]here is no longer a cohesive, singular Modern Orthodoxy"; see further below.
Title: Young Judaea
Content:  Young Judaea is a peer-led Zionist youth movement that runs programs throughout the United States for Jewish youth in grades 2–12. In Hebrew, Young Judaea is called Yehuda Hatzair (יהודה הצעיר) or is sometimes referred to as Hashachar (השחר), lit. "the dawn". Founded in 1909, it is the oldest Zionist youth movement in the United States.
Title: Haredi Judaism
Content:   Haredi Judaism (יהדות חֲרֵדִית Yehadut Ḥaredit, ; also spelled Charedi in English; plural Haredim or Charedim) consists of groups within Orthodox Judaism which are characterized by their strict adherence to halakha (Jewish law) and traditions, in opposition to modern values and practices. Its members are usually referred to as ultra-Orthodox in English; however, the term "ultra-Orthodox" is considered pejorative by many of its adherents, who prefer terms like strictly Orthodox or Haredi. Haredi Jews regard themselves as the most religiously authentic group of Jews, although other streams of Judaism disagree. Some scholars have suggested that Haredi Judaism is a reaction to societal changes, including emancipation, the Haskalah movement derived from the Enlightenment, acculturation, secularization, religious reform in all its forms from mild to extreme, the rise of the Jewish national movements, etc. In contrast to Modern Orthodox Judaism, followers of Haredi Judaism are usually uncompromising in their adherence

Haredi is less accommodating to modernity and has less interest in non-Jewish disciplines, and it may be distinguished from Modern Orthodox Judaism in practice by its styles of dress and more stringent practices. Subsets of Haredi Judaism include Hasidic Judaism, which is rooted in the Kabbalah and distinguished by reliance on a Rebbe or religious teacher; their opponents Misnagdim (Lithuanian); and Sephardic Haredi Judaism, which emerged among Sephardic and Mizrahi (Asian and North African) Jews in Israel. "Centrist" Orthodoxy (Joseph B. Soloveitchik) is sometimes also distinguished.

Note that claims of this nature have been commonplace within Orthodox Judaism since the first "reforms" of Samson Raphael Hirsch and Azriel Hildesheimer. Thus, in Europe of the early 19th century, all of Judaism that differed from the strictest forms present at the time was called "Reform". Then, as now, Modern Orthodoxy took pains to distance its "reforms", which

In Central Europe, followed by Great Britain and the United States, Reform (or Liberal) Judaism developed, relaxing legal obligations (especially those that limited Jewish relations with non-Jews), emulating Protestant decorum in prayer, and emphasizing the ethical values of Judaism's Prophetic tradition. Modern Orthodox Judaism developed in reaction to Reform Judaism, by leaders who argued that Jews could participate in public life as citizens equal to Christians while maintaining the observance of halakha. Meanwhile, in

Content:  It is also noted that many Modern Orthodox are "behaviorally modern" as opposed to "ideologically modern", and, in truth, fall outside of "Modern" Orthodoxy, at least in the philosophical sense; see below. This phenomenon is sometimes termed "Social Orthodoxy". The distinction is as follows: The ideologically modern are "meticulously observant of Halakha", and their interaction with the secular comprises a tangible expression of their ideology, wherever it may lie on the spectrum described. The "behaviorally modern", on the other hand, define themselves as "Modern Orthodox" only in the sense that they are neither Haredi ("Ultra-Orthodox") nor Conservative: these, in other words, are "not deeply concerned with philosophical ideas", and, often, are not as careful in their observance. This "Orthodoxy of convenience" has maintained a certain stability over time: as long as these don't seek to legitimize their behaviour in halakhic terms, the leadership of the (Modern) Orthodox world have no particular difficulty with them.
