Maybe there actually is a genuinely post-Christian future for America.

Here are some generally agreed-upon facts about religious trends in the United States. Institutional Christianity has weakened drastically since the 1960s. Lots of people who once would have been lukewarm Christmas-and-Easter churchgoers now identify as having “no religion” or being “spiritual but not religious.” The mainline-Protestant establishment is an establishment no more. Religious belief and practice now polarizes our politics in a way they didn’t a few generations back.

What kind of general religious reality should be discerned from all these facts, though, is much more uncertain, and there are various plausible stories about what early-21st century Americans increasingly believe. The simplest of these is the secularization story — in which modern societies inevitably put away religious ideas as they advance in wealth and science and reason, and the decline of institutional religion is just a predictable feature of a general late-modern turn away from supernatural belief.

But the secularization narrative is insufficient, because even with America’s churches in decline, the religious impulse has hardly disappeared. In the early 2000s, over 40 percent of Americans answered with an emphatic “yes” when Gallup asked them if “a profound religious experience or awakening” had redirected their lives; that number had doubled since the 1960s, when institutional religion was more vigorous. A recent Pew survey on secularization likewise found increases in the share of Americans who have regular feelings of “spiritual peace and well-being.” And the resilience of religious impulses and rhetoric in contemporary political movements, even (or especially) on the officially secular left, is an obvious feature of our politics.
