Just thought I would put in my 2 cents.
The Bible talks about beating obstinate SONS even with a rod of correction if necessary.
Spanking is something that can be good for training little children but if it hurts the hand of the mother to spank, it is probably ineffective or abusive to the child. It is usually not necessary with most girls.
No woman should ever be beaten or treated like a child by her husband. Men who let this kind of thing happen to women who they know about are not men.
Remember they beat Paul (a man) with rods for preaching the Gospel. They were publicly humiliating him, but he took it patiently as a good soldier of Jesus.
