As his wife slept, he fumbled through the darkness for his laptop. After a few quick searches with the terms “pastor” and “atheist,” he discovered that a cottage industry of atheist outreach groups had grown up in the past few years. Within days, he joined an online network called the Clergy Project, created for clerics who no longer believe in God and want to communicate anonymously through a secure Web site.

DeWitt began e-mailing with dozens of fellow apostates every day and eventually joined another new network called Recovering From Religion, intended to help people extricate themselves from evangelical Christianity. Atheists, he discovered, were starting to reach out to one another not just in the urban North but also in states across the South and West, in the kinds of places­ DeWitt had spent much of his career as a traveling preacher. After a few months he took to the road again, this time as the newest of a new breed of celebrity, the atheist convert. They have their own apostles (Bertrand Russell, Richard Dawkins, Christopher Hitchens) and their own language, a glossary borrowed from Alcoholics Anonymous, the Bible and gay liberation (you always “come out” of the atheist closet).

Clergy Project is getting some mainstream press.
