I was thinking originally of the passage in 1 Corinthians 7:11 in which Paul certainly appears to sanction separation for two believers, but commands that it must either result in celibacy or reconciliation. It looks like Paul’s acknowledgment that sometimes cohabitation isn’t working—as with the abusive spouse you mentioned. But if there is no adultery or desertion involved, then separation appears to be the Scriptural remedy.
For the most part, I agree with you.
However, I’ve never been able to reconcile forced to stay in a truly abusive relationship with a requirement of God. Had an acquaintance whose father told her, “You’ve made your bed; now you’ve got to lie in it.” Her abusive husband took the cake. I won’t get into it, he could have been a Law & Order episode.
So, I see in the 1 Corinthians passage an actual biblical allowance of DISSOLUTION of marriage...no longer bound. I’ll have to answer to God someday, I suppose, if I’m wrong, because I’m also a minister and I’ve shared those thoughts in public.
May the Lord have mercy.
