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.
