This Second Edition represents Bellah's summation of his views on civil religion in America. In his 1967 classic essay "Civil Rights in America," Bellah argued that the religious dimensions of American society—as distinct from its churches—has its own integrity and required "the same care in understanding that any religion."

This edition includes his 1978 article "Religion and the Legitimation of the American Republic," and a new Preface.

The Cross of War documents the rise of “messianic interventionism”—the belief that America can and should intervene altruistically on behalf of other nations. This stance was first embraced in the Spanish-American War of 1898, a war that marked the dramatic emergence of the United States as an active world power and set the stage for the foreign policy of the next one hundred years. Responding to the circumstances of this war, an array of Christian leaders carefully articulated and defended the notion that America was responsible under God to extend freedom around the world—by force, if necessary. Drawing from a wide range of sermons and religious periodicals across regional and denominational lines, Matthew McCullough describes the ways that many American Christians came to celebrate military intervention as a messianic sacrifice, to trace the hand of God in a victory more painless and complete than anyone had imagined, and to justify the shift in American foreign policy as a divine calling.

In recent years a series of highly publicized controversies has focused attention on what are arguably the sixteen most important words in the U.S. Constitution: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof." The ongoing court battles over the inclusion of the words "under God" in the Pledge of Allegiance, the now annual cultural quarrel over "Merry Christmas" vs. "Happy Holidays," and the political promotion of "faith-based initiatives" to address social problems—all reflect competing views of the meaning of the religious liberty clauses of the First Amendment.

Such disputes, as Bruce T. Murray shows, are nothing new. For more than two hundred years Americans have disagreed about the proper role of religion in public life and where to draw the line between church and state. In this book, he reexamines these debates and distills the volumes of commentary and case law they have generated. He analyzes not only the changing contours of religious freedom but also the phenomenon of American civil religion, grounded in the notion that the nation's purpose is sanctified by a higher authority—an idea that can be traced back to the earliest New England colonists and remains deeply ingrained in the American psyche.

Throughout the book, Murray connects past and present, tracing the historical roots of contemporary controversies. He considers why it is that a country founded on the separation of church and state remains singularly religious among nations, and concludes by showing how the Supreme Court's thinking about the religious liberty clauses has evolved since the late eighteenth century.
