From another thread:
So what is the reason why evangelicals - including Baptists have a divorce rate similar to non-believers?
They don't.
"
“Christians divorce at roughly the same rate as the world!”
It's one of the most quoted stats by Christian leaders today. And it's perhaps one of the most inaccurate.
At bottom, it is used to explain that Christians are not doing well in living out their faith. But it could also be taken as a statement that redemption by and real discipleship under Jesus makes no real difference when it comes to marriage. But mainstream sociologists would tell us that taking one's faith very seriously—in word and deed—does indeed make a marked positive difference in the health and longevity of marriage. Based on the best data available, the divorce rate among Christians is significantly lower than the general population.
Here's the truth…
People who seriously practice a traditional religious faith—whether Christian or other—have a divorce rate markedly lower than the general population.
The factor making the most difference is religious commitment and practice.
What appears intuitive is true. Couples who regularly practice any combination of serious religious behaviors and attitudes—attend church nearly every week, read their bibles and spiritual materials regularly; pray privately and together; generally take their faith seriously, living not as
perfect disciples, but
serious disciples—enjoy significantly lower divorce rates than mere church members, the general public, and unbelievers."
