In this dissertation, an interdisciplinary project combining American religious history, American immigration history, and methods from cultural and social history, I will explore the important issue of religious pluralism for contemporary American religious communities by studying one of the most extreme cases of religious plurality in the world. Aside from recounting Flushing’s significant place in the history of religious freedom and toleration in America, I will show what factors have led to such an extraordinary case of religious plurality on Bowne Street and modern Flushing and describe the range of ethnic relations there to help illustrate the kinds of processes at work elsewhere in the U.S. We will be able to glimpse the future of American religion in Flushing particularly well not only because the striking exaggeration of its diversity makes the issues more sharply defined, but also because the area and its local tradition of religious freedom and toleration mirrors the nation and the same ideology of the First Amendment in microcosm.
