WL Herberg’s Protestant-Catholic-Jew: An Essay in American Religious Sociology was originally published in 1955. It is a classic work in the sociology of religion, once described by the noted historian of American religion Martin E. Marty as “the most honored discussion of American religion in midtwentieth-century times.” But shortly after making this favorable judgment, Marty went on to assert that Herberg “failed to anticipate almost every important turn in subsequent American life.”
