The close bond between Christianity—evangelical Protestantism, in particular—and the American presidency began to form in the 1950s. That decade was a time of extraordinary religious revival: Church membership rose from 49 percent of Americans in 1940 to 69 percent in 1960. And President Dwight D. Eisenhower—along with Graham—played an important part in encouraging this spiritual devotion. In fact, Eisenhower played a very personal role in popularizing religious faith in America.
