the Land is Law principle must be universally applied and subject virtually everything to current norms and needs, far beyond its weight in conventional Jewish Law. While Reform rabbis in 19th-century Germany had to accommodate conservative elements in their communities, at the height of "Classical Reform" in the United States, halakhic considerations could be virtually ignored and Holdheim's approach embraced. In the 1930s and onwards, Rabbi Solomon Freehof and his supporters reintroduced such elements, but they too regarded Jewish Law as too rigid a system. Instead, they recommended that selected features will be readopted and new observances established in a piecemeal fashion, as spontaneous minhag (custom) emerging by trial and error and becoming widespread if it appealed to the masses. The advocates of this approach also stress that their responsa are of non-binding nature, and their recipients may adapt them as they see fit. Freehof's successors, such as Rabbis Walter Jacob and Moshe Zemer, further elaborated the notion of "Progressive Halakha" along the same lines. Messianic age and election Reform sought to accentuate and greatly augment the universalist traits in Judaism, turning it into a faith befitting the Enlightenment ideals ubiquitous at the time it emerged. The tension between universalism and the imperative to maintain uniqueness characterized the movement throughout its entire history. Its earliest proponents rejected Deism and the belief that all religions would unite into one, and it later faced the challenges of the Ethical movement and Unitarianism. Parallel to that, it sought to diminish all components of Judaism that it regarded as overly particularist and self-centered: petitions expressing hostility towards gentiles were toned down or excised, and practices were often streamlined to resemble surrounding society. "New Reform" laid a renewed stress on Jewish particular identity, regarding it as better suiting popular sentiment and need for preservation. One major expression of that, which is the first clear Reform doctrine to have been formulated, is the idea of universal Messianism. The belief in redemption was unhinged from the traditional elements of return to Zion and restoration of the Temple and the sacrificial cult therein, and turned into a general hope for salvation. This was later refined when the notion of a personal Messiah who would reign over Israel was officially abolished and replaced by the concept of a Messianic Age of universal harmony and perfection. The considerable loss of faith in human progress around World War II greatly shook
