These two come together because having children tends to drive men and women to participate in religious life; that family participation, in turn, enculturates their children into religious life and makes it more likely to continue when they are grown. In other words, "belief" and "belonging" are severable practices which Churches must strive to put back together.
Finally, my argument isn’t that Euro-American religion is dying, but that it’s changing. Many millions believe without belonging, and that number will grow. The challenge for churches, then—for all churches—is to decide how to respond to this new world, so hostile to institutions and hierarchies, so resentful of intrusions into what’s so widely seen as private space and private morality. How do you speak to those who wish to believe, but dread belonging?
