Passages that reflect the culture of another time, or that are taken out of context, or that are misunderstood and viewed with abuse-colored glasses. The Bible has been used in many ways in history to gloss over great evils, and using Scripture to justify domestic violence is one of them. There are times when God must weep bitter tears over what is done by those who say they follow him. I've heard of clergy telling people being abused to remain in the situation for the sake of the marriage, or tell children that if they were only better behaved they would not be beaten. All the justifications are lies and distortions, no matter where they come from.
Domestic violence is about the abuse of power and it's about treating other people as things.
It's about my emotion of anger being more important than another person's right to live in safety. It's about having a role in a family and using that as a cover for a need to dominate others. Domestic violence is against faith, and God, and the meaning of love. Simply put, no Scripture can be used to justify domestic violence. No sacrament can be used as a reason to allow it to go on.
