And again, read the entirety of scripture before jumping to conclusions.
Jesus spoke to the woman at the well (who was living in sin) without sentencing her to death. Jesus spoke to the woman who was caught in the act of adultery without sentencing her to death. I guess He sees forgiveness and restoration as better then destruction. Good rule to follow.
What I would support is that the adulterer (or adulteress) lose everything in the ensuing divorce. Children, house, cars, all goods or finances belonging to the marriage. If you break the marriage covenant you lose everything (if the wronged spouse chooses not to forgive you)
Divorce should be in cases of adultery or provable abuse only.
