I’d like to offer an alternative perspective. While no one enjoys a divorce and the process often leaves children feeling sad and confused for a time, of all the possible ill effects, losing interest in religion is by far the least worrisome.
I guess it depends on how children of divorce experience this loss. In the report, we discuss research for example by Melinda Denton and Annette Mahoney. Their separate papers reveal that the impact of divorce on children’s religious lives depends in part upon where the children were, religiously, before the divorce, and whether or not they viewed their parents’ marriage as something sacred.
