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 [Scientific] 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.

Modern Orthodoxy

Modern Orthodoxy comprises a fairly broad spectrum of movements each drawing on several distinct, though related, philosophies, which in some combination provide the basis for all variations of the movement today; these are discussed below.

Characteristics

In general, Modern Orthodoxy's "overall approach.. is the belief that one can and should be a full member of modern society, accepting the risks to remaining observant, because the benefits outweigh those risks". Jews should engage constructively with the world that they are in to foster goodness and justice within both themselves and the larger community, such as by avoiding sin in their personal lives while also caring for the unfortunate.
