A domestic discipline marriage is one in which one partner in the marriage is given authority over the other and has the means to back the authority, usually by spanking.
A Christian Domestic Discipline marriage is one that is set up according to Biblical standards; that is, the husband is the authority in the household. The wife is submissive to her husband as is fit in the Lord and her husband loves her as himself. He has the ultimate authority in his household, but it is tempered with the knowledge that he must answer to God for his actions and decisions. He has the authority to spank his wife for punishment, but in real CDD marriages this is taken very seriously and usually happens only rarely. CDD is so much more than just spanking. It is the husband loving the wife enough to guide and teach her, and the wife loving the husband enough to follow his leadership. A Christian marriage embodies true romance and a Christian man a true hero.
Though this seems unusual in today's United States, this kind of marriage has been practiced throughout history and is still practiced in many parts of the world today.
