When I wrote Stuck in the Present, I was not thinking about megachurches per se, but this excerpt describes a concern that seems more formidable in larger churches:

“A community, especially a Christian one, is a group of people who share something in common that transcends socioeconomic or racial backgrounds. What Christians share is a common history—a living tradition. When we lose sight of this living tradition, we put ourselves in a perilous situation. With a sketchy understanding of our common identity as Christians, we are no longer able to have true community with one another.”
