Everyone else seems to have really liked this book. I'm afraid I'm an exception. I found it repetitive, somewhat tendentious, and did not really learn anything new. He says at the start that he wrote it because there is nothing else on the subject, which is nonsense. There is an extensive literature, some of which he quotes! And other books I have read on the subject (of why the church is dominated by women) have been more nuanced and complete in their analysis, even if not so 'punchy' in delivery, in my view. (I am a vicar of a small evangelical anglican church, so speak from that pespective).
He claims that THE one big reason there are so few men in church is because the church has been feminised, and he claims to give ways to put this right. Other books suggest this is one reason amongst several - which I find more convincing. Also, I felt that all his practical solutions were only viable in a large church.
I also found the style irritating. Rather than putting forward a reasoned thesis he seemed to be trying to beat the reader on the head with the same message on almost every page - for 230 pages! He seems to take the view that, even if it's wrong, men are sexist and a bit immature, and the church (particularly women) need to accept men as they are if they want to get them in church. When I think of some of the young couples on the fringe of my church, the underlying male chauvinism would put them off church if they read it.
That said, I agree that there is considerable truth in his basic message, and I'm glad that others have found it helpful. It was because of their reviews that I bought the book!
