Last week in "Dear Prudence," Slate.com's wonderfully sharp advice column, Emily Yoffe published a compelling letter from a once-devout reader about the crisis of faith he was experiencing. "I am devastated by its practical implications," he wrote about the impact of his religious doubt on his marriage to a "wonderful Christian woman." "My loss of faith could be shattering for just about every close relationship I have."
"I continue to believe that religion brings the potential for a great many good things," the man added. "I could probably continue going through the motions, except that I believe in morality and honesty, and I hate pretending to be something that I'm not. It would be very hurtful for my wife to hear about my loss of faith, but it might be even more damaging for me to continue lying. Should I maintain my secret as long as possible in the hopes that it never becomes necessary to reveal it?"
