Here is good news for those of us who have been continually told that divorce rates amongst Christians are comparable to those of the general population: The Christian Divorce Rate Myth.
W. Bradford Wilcox, a leading sociologist at the University of Virginia and director of the National Marriage Project, finds from his own analysis that “active conservative Protestants” who regularly attend church are 35 percent less likely to divorce compared to those who have no affiliation. Nominally attending conservative Protestants are 20 percent more likely to divorce, compared to secular Americans . . . .
The divorce rates of Christian believers are not identical to the general population — not even close. Being a committed, faithful believer makes a measurable difference in marriage.
Saying you believe something or merely belonging to a church, unsurprisingly, does little for marriage. But the more you are involved in the actual practice of your faith in real ways — through submitting yourself to a serious body of believers, learning regularly from Scripture, being in communion with God though prayer individually and with your spouse and children, and having friends and family around you who challenge you to take [your marriage] seriously — the greater difference this makes in strengthening both the quality and longevity of our marriages. Faith does matter and the leading sociologists of family and religion tell us so.
