Feldhahn estimates the overall divorce rate for the country is around 31 percent. The studies of people who regularly go to church all show a much lower divorce rate for them.
"Maybe 15 percent, maybe 20 percent for all marriages. First marriages, second marriages, third marriages," Feldhahn explained.
Feldhahn cited one example where a pastor tracked 143 couples who he had married.
"It was 25, 27 years later. Less than 10 percent had been divorced," she stated.
Feldhahn hopes these facts she's uncovered become widespread...
"People need to be able to look around the average congregation and say, 'You know what, most of these people will have strong and happy marriages for a lifetime. Doing what God says matters. This is a big deal to know."
It's long been believed that half of America's Christian marriages end in divorce. But when Harvard-trained researcher Shaunti Feldhahn tried to find the actual research to prove those points, she couldn't.
