A New Awakening.

The religious upsurge that followed World War II continued into the 1950s. By all concrete measurements — membership, contributions, media attention, films, and best-selling books — interest in religion was so high in the United States that optimists talked of a new awakening, with hopes that this one would affect American culture as deeply as those of the eighteenth and nineteenth centuries. But critics from both the right and left of the religious spectrum speculated whether religion had made its peace with the secular culture and had become just another commodity to be consumed in the American marketplace.

Optimists, however, pointed to concrete achievements. By 1960 an astonishing 63.6 percent of the population was affiliated with some religious group, and 60 percent of the people said they went to weekly religious services. The average annual monetary contribution to religious groups was at an all-time high.
