There is actually a thing called “Christian Domestic Discipline”, in which husbands hit their wives when the wife allegedly does wrong, and twist the Bible to call it a Christian thing to do. (Sources here and here.) Of course, this is a covert movement, and the practitioners “convert” others to their activities in secret.
According to a commenter on that blog, Anne Garbozi Evans,
…my research has shown, while it may very well be more frequently popping up in patriarchal circles, it is by no means limited to those congregations. The only type of congregations that all of these wife-spanking people refused to go to were ones that ordained female pastors and taught egalitarianism. Any church that taught complementarianism was fair game for them to attend: their words not mine… many said they secretly suspected they weren’t the only ones to practice wife-spanking. They also heavily discussed how to bring up the topic of wife-spanking to your friend so as to “evangelize” them on the topic. They esp. thought they had a moral duty to tell any friends going through a divorce about wife-spanking as a way to “save their marriages.”
