I learned about this book on an Issues Etc podcast. If you are not a reader, that is a good option.
The review leaves out what I consider to be a key insight of the book. Page 15: "Compared to secular men, devout Christian family men who attend church regularly are more loving husbands and more engaged fathers. They have the lowest rate of domestic violence of any major group in America."
On the same page, "Surprisingly, research has found that nominal Christian men have the highest rates of divorce and domestic violence -- even higher than secular men".
I don't find this "surprising" and believe that "nominal Christians" who are CINOs (Christians In Name Only) are a greater threat to the church than the secular culture because they their bad behaviour allows the secular culture to (correctly) based on statistics, say that Christian homes are "on average" the same as non-Christian homes. The CINO men pick and choose what parts of doctrine they like (man as ruler of home and wife, whatever he does wrong ... drinking, womanizing, staying out late, etc is "the wife's fault" because she is not "meeting his needs". He ignores the need to be willing to sacrifice his life for his wife and family if required, and to treat her gently as the "weaker vessel".
Page 19 gives us the modern world model of a "real man". "To be a real man, means to be tough, strong, never show weakness, win at all costs, suck it up, play through pain, be competitive, get rich, get laid".
While she does discuss some of the contributing reasons for this ... women's rights, women in the workforce, feminism, the secular message to woman after the pill and abortion that women have a right to all the sexual freedom that men had, etc, she lays most of the responsibility on men. Since God calls men to be leaders, there is certainly truth there.
She leaves out what I see as another major contributing factor, the many supposedly "Christian" denominations (ELCA) that are CINOs ... even if they are "regular attenders", they likely have the same numbers as secular, since they really are.
Not emphasized much however, is that when modern "liberated" women set themselves up as the "stronger vessel", and take on traditional male characteristics as not communicating, taking charge of how children are raised, etc, the story is not quite so simple, and may put the "not so real men" -- more sensitive, more emotional, less willing to fight, needy of strong communication, etc in positions similar to the traditional woman dealing with a CINO man.
On balance, a worthy book.
