Honestly I don’t know what to rate this book. I get that John Piper here is trying to cast the vision for biblical masculinity and femininity and what that means for today. In other contexts I love John’s hermeneutic of seeking the fullest expressions of things instead of minimalist expressions. For instance, when talking on Hebrews 12, John talks about how we should not only ask, “is this activity sinful,” but, “is it weighing me down in my run?” The first question— is it sinful— is often seeking to do the minimal amount to live a godly life. The latter question seeks to do lead the fullest expression of a godly life.
So when he turns to masculinity and femininity, he isn’t answering what mere masculinity and mere femininity are, but to do so, he definitely goes out of the biblical text, adding things that he would consider weights to lead a fully masculine or fully feminine life.
I do really believe God leaves authority in place in the Bible because by it we get to practice things that otherwise would be impossible or largely impractical— like submission, deference, humility, etc.— and in the household codes of Ephesians and Colossians, Paul seems to draw parallels of hierarchy between parents and kids, slaves and masters, and wives and husbands. I don’t know what that means for complementarity today, but John’s casting of vision for it seemed too extreme. I don’t know if I’m any closer to finding what I think on this topic. Excited to read some egalitarian perspectives.
