Apologies if being unclear—not my intent. I have heard the argument that scripture allows D for adultery, and this is an especially common argument for Protestant Christians; the Catholic Church teaches that D is only morally permissible “[i]f civil divorce remains the only possible way of ensuring certain legal rights, the care of the children, or the protection of inheritance, it can be tolerated and does not constitute a moral offense.” (Catechism of the Catholic Church #2383). I would then imagine that following a civil D, a church annulment should follow next. (Really don’t mean to get into the theological weeds—if you want to know more, message me, or hop over to my thread. I talk about topics like this in my day job.).
