It's not often I find myself face to face with a new species of nutbaggery, but Christian Domestic Discipline:
Loving Wife Spanking in a Christian Marriage leaves me speechless. A taste:

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.

I guess it could conceivably be considered in the Purity Ball clade, in a bizarre, negative-space kinda way...
