Book excerpt: America's armed forces were the products of one of the most diverse and dynamic religious cultures in the western world and were the largest ever to be raised by a professedly religious society. Despite constitutional constraints, a pre-war 'religious depression', and the myriad pitfalls of war, religion played a crucial role in helping more than sixteen million uniformed Americans through the ordeal of World War II, a fact that had profound and far-reaching implications for the religious development of post-war America.--Provided by publisher.
