Steven K. Green, renowned for his scholarship on the separation of church and state, charts the career of the concept and helps us understand how it has fallen into disfavor with many Americans. In 1802, President Thomas Jefferson distilled a leading idea in the early American republic and wrote of a wall of separation between church and state. That metaphor has come down from Jefferson to twenty-first-century Americans through a long history of jurisprudence, political contestation, and cultural influence. This book traces the development of the concept of separation of church and state and the Supreme Court's application of it in the law. Green finds that conservative criticisms of a separation of church and state overlook the strong historical and jurisprudential pedigree of the idea. Yet, arguing with liberal advocates of the doctrine, he notes that the idea remains fundamentally vague and thus open to loose interpretation in the courts. As such, the history of a wall of separation is more a variable index of American attitudes toward the forces of religion and state. Indeed, Green argues that the Supreme Court's use of the wall metaphor has never been essential to its rulings. The contemporary battle over the idea of a wall of separation has thus been a distraction from the real jurisprudential issues animating the contemporary courts.

In a powerful challenge to conventional wisdom, Philip Hamburger argues that the separation of church and state has no historical foundation in the First Amendment. The detailed evidence assembled here shows that eighteenth-century Americans almost never invoked this principle. Although Thomas Jefferson and others retrospectively claimed that the First Amendment separated church and state, separation became part of American constitutional law only much later. Hamburger shows that separation became a constitutional freedom largely through fear and prejudice. Jefferson supported separation out of hostility to the Federalist clergy of New England. Nativist Protestants (ranging from nineteenth-century Know Nothings to twentieth-century members of the K.K.K.) adopted the principle of separation to restrict the role of Catholics in public life. Gradually, these Protestants were joined by theologically liberal, anti-Christian secularists, who hoped that separation would limit Christianity and all other distinct religions. Eventually, a wide range of men and women called for separation. Almost all of these Americans feared ecclesiastical authority, particularly that of the Catholic Church, and, in response to their fears, they increasingly perceived religious liberty to require a separation of church from state. American religious liberty was thus redefined and even transformed. In the process, the First Amendment was often used as an instrument of intolerance and discrimination.

In The Religion Clauses, Erwin Chemerinsky and Howard Gillman examine the extremely controversial issue of the relationship between religion and government. They argue for a separation of church and state. To the greatest extent possible, the government should remain secular. At the same, time they contend that religion should not provide a basis for an exemptions from general laws, such as those prohibiting discrimination or requiring the provision of services.
