Why does it matter if millennials’ rupture with religion turns out to be permanent? For one thing, religious involvement is associated with a wide variety of positive social outcomes like increased interpersonal trust and civic engagement that are hard to reproduce in other ways. And this trend has obvious political implications. As we wrote a few months ago, whether people are religious is increasingly tied to — and even driven by — their political identities. For years, the Christian conservative movement has warned about a tide of rising secularism, but research has suggested that the strong association between religion and the Republican Party may actually be fueling this divide. And if even more Democrats lose their faith, that will only exacerbate the acrimonious rift between secular liberals and religious conservatives.
“At that critical moment when people are getting married and having kids and their religious identity is becoming more stable, Republicans mostly do still return to religion — it’s Democrats that aren’t coming back,” said Michele Margolis, author of “From the Politics to the Pews: How Partisanship and the Political Environment Shape Religious Identity.” in an interview for our September story.
