According to Gallup, church attendance hovered around 39 percent in the 1930s and 1940s.7 It increased in the 1950s, when Dwight D. Eisenhower encouraged Americans everywhere to go to services. This was the sales pitch: America was now at war with communism, which was perpetuated by atheism. Americans could differentiate themselves from the godless hordes by exercising their freedom of religion. The call was taken up by religious leaders such as Billy Graham, and soon going to church was more than just something for the religious, it was part of being a good American.
