His view of women is reprehensible and his beliefs concerning their abuse is disgusting. I have to agree with Sarah Moon who writes on the twitter-
John Piper’s notion that his telling women to “endure abuse for a season” needs only “clarification” is insulting to women’s intelligence.
I would only add that John Piper’s advice that women endure abuse is both sub Christian and anti-theological. It is itself abuse and it empowers abusers to continue treating women badly. Not only should he be ashamed of his views, he should be denounced for them.
