This chapter looks at the rise of neo-evangelicalism in the late- and post-war period, an alliance that had only barely begun to emerge. The National Association of Evangelicals was founded during the war, in part in counterpoint to, but still with significant overlap with, the Federal Council of Churches. Harold J. Ockenga himself was a mainline Presbyterian animated by a need to combat modernism but suspicious of separating evangelicalism from the broader American mainstream, including its major denominations. Evangelicalism needs the diversity of its thick theological traditions underneath its thin umbrella commitments, and such thickness is where issues of theological ethics and especially political ethics are worked out. The modern forms of the so-called “Christian Right” have some of their roots in conservative evangelical anti-globalism, and as such, are often invoked as shorthand for evangelicalism generally, but this is not the whole story.
