Matthew Hedstrom

The most critical of these new religious developments for twentieth-century religious liberalism were a renewed and transformed emphasis on mystical practice and experience, the healing ministry known as mind cure, and the rise of modern psychology. These three interrelated spiritual innovations spread as significant components of popular religion in large part through the mass print media. Rather than religious movements dependent on revivalism or church life, these were first and foremost discourses, creatures of the printed word. Initially explored only by an avant-garde of liberal intellectuals late in the nineteenth century, the new books and ideas emerging at the margins of liberal Protestantism eventually reached a nation-wide middle-class audience. The mass media unleashed by nineteenth-century evangelicalism enabled the alternative spiritualities of the twentieth century to flourish, especially with the rise of religious middlebrow culture in the decades after World War I.
