>As someone who only sometimes attends church, I wonder why that has a higher risk of divorce than never attending or always attending. Maybe lack of commitment? My speculation is that this could be a sign that the couple disagrees on religion and is unable to reconcile it. One partner might attend sporadically, but they're really not committed to it as you said.
