“I’m spiritual but not religious.” You’ve heard it—maybe even said it—before. But what does it actually mean? Can you be one without the other? Once synonymous, “religious” and “spiritual” have now come to describe seemingly distinct (but sometimes overlapping) domains of human activity. The twin cultural trends of deinstitutionalization and individualism have, for many, moved spiritual practice away from the public rituals of institutional Christianity to the private experience of God within. In this conclusion of a two-part series on faith outside the church (read the first part, on those who “love Jesus but not the church”), Barna takes a close look at the segment of the American population who are “spiritual but not religious.” Who are they? What do they believe? How do they live out their spirituality daily?
