Abuse breaks the marriage covenant. The abuser broke it — not the person who leaves. The verse most commonly used to trap victims in dangerous marriages is half a verse, and the half that gets cut off condemns marital violence. The passage used to enforce wifely submission actually commands mutual submission, has no verb in the Greek for the wife's role, and spends nine verses commanding husbands to sacrificial love — every word of which an abusive husband has violated. The Bible does not tell you to stay. The Bible consistently sides with the oppressed against the violent, commands liberation from bondage, and treats covenant violation — not the acknowledgment of covenant violation — as the sin. If you are being hurt, leaving is not unfaithfulness. It is the most theologically honest thing you can do.
