Despite these benefits, church attendance has fallen substantially among the members of the white working class in recent years, just when they need it most. Though working-class whites earn, on average, more than working-class people of other ethnicities, we are in a steep social decline. Incarceration rates for white women are on the rise, white youths are more likely than their peers from other groups to die from drug overdoses and rates of divorce and domestic chaos have skyrocketed. Taken together, these statistics reveal a social crisis of historic proportions. Yet the white church — especially the evangelical church that claims the most members — has seemingly disappeared.

Though many working-class whites have lost any ties to church, they haven’t necessarily abandoned their faith. More than one in three identify as evangelical, and well over 75 percent claim some Christian affiliation. But that faith has become deinstitutionalized. They may watch megachurch broadcasts or join prayer circles on Facebook, but they largely avoid the pews on Sunday. Consequently, many absorb the vernacular and teachings of modern Christianity, but miss out on the advantages of church itself.

This deinstitutionalization of the faith has occurred alongside its politicization. It’s hard to believe that in 1976, evangelicals helped deliver the White House to the liberal Democrat Jimmy Carter. But fueled by social issues like abortion, the religious right soon began to exercise broad influence among American Christians. By 2004, “values voters” became so synonymous with the Republican Party that George W. Bush’s re-election was largely attributed to them.

While it’s hard to fault people for voting their conscience, this fusion of religion and politics necessarily forces people to look externally. The sometimes tough love of the Christian faith of my childhood demanded a certain amount of self-reflection and, occasionally, self-criticism. While faith need not be monolithic — it can motivate both voting behavior and character development — focus matters. A Christianity constantly looking for political answers to moral and spiritual problems gives believers an excuse to blame other people when they should be looking in the mirror.

Evangelicals appear to have taken this message to heart. The most significant evangelical contribution to fiction in the past 20 years was the apocalyptic “Left Behind” series. The books are riveting, but their core message is that corrupt, evil elites have gone to war against Christians. Some version of this idea — whether delivered in church or on TV — finds its way into many topics in a modern evangelical sermon: Evolution is a lie that secular science tells to counter the biblical creation story, the gay rights movement usurps God’s law. Recently, a friend sent me the online musings of a televangelist who advised his thousands of followers that the Federal Reserve achieved satanic ends by manipulating the world’s money supply. Paranoia has replaced piety.
