Book excerpt: Since the 1972 publication of Dean M. Kelley's Why Conservative Churches Are Growing, discussion of the Protestant mainline has focused on the tradition's decline. Elesha J. Coffman's The Christian Century and the Rise of Mainline Protestantism tells a different story, using the lens of the influential periodical The Christian Century to examine the rise of the mainline to a position of cultural prominence in the first half of the twentieth century.
