Coming in December 2025

The Nones, Dones, Unchurched, spiritual but not religious (SBNRs). Call them what you will - they're a dominant force in American religion and the plurality among Millennials and Gen Zers. In Church Tomorrow? Stephanie Spellers presents hard truths about declining religious affiliation in America, paired with stories and wisdom from her interviews with dozens of young people who either grew up with no faith or gave up formal religion. Along the way, she joins hundreds in a yoga circle at San Francisco's Grace Cathedral; in Atlanta, Georgia, she attends Sunday Assembly, a secular congregation that caters to agnostics and atheists; just outside the Twin Cities, she interviews college students exploring crystals and tarot decks; and in New York City she comes home to meet spiritual-but-not-religious young adults who once attended her own church. And that's only the beginning.

As she listens and learns, Spellers asks: Why are younger generations passing on church? What spiritual pathways and communities are they creating? And how could their insights help to shape the future of Christian community? Listen up - today's young Nones and Dones have a prophecy for the church of tomorrow.

"The wonder of this book is that Spellers begins with a formidable complex of data and history concerning disaffiliation from organized religion and the state of faith in America, and she has made it accessible, understandable, and clear. That is no small accomplishment. But that is only the beginning.  ...  In the powerful set of testimonies at the book’s center, Spellers has chronicled a selection of the realities and hopes of America’s nonreligious young adults. ... They give voice to deep hopes, troubles, and questions we in the church often miss. Because of their offering, new possibilities beyond the usual institutional probabilities can emerge."

"Stephanie Spellers knows the church and knows the voices of those who seek spiritual community like no one else. Her newest book is a rich dive into the voices of spiritual young adults who do not find belonging in Christian churches. This is an important read for those of us who seek to serve them from the church."
