Adrian is a welcome guide for those who are mystified by what they hear as church teaching. He is an academic who has made a profound study of the subject and already written a number of academic books, but here he writes a basic book for the intelligent reader who is prepared to get to grips with the subject. There are plenty of people who will want to say "rubbish" because they feel constrained to stick with what church leaders have taught. But if you are prepared to wrestle with the topic you can be led to understand why he is saying that the Gospel, the good news, that Jesus brought, does not compel us to stick with the thinking of not only the culture before Jesus' birth but also with our culture that has developed over the intervening years.
Despite the book's small size it compresses a vast amount of research, for which references are available. I wish the subject and book were simpler. But if too simplistic could it really deal with the objections to outdated teaching. It was probably easier for me to accept having met spiritual leaders who have lived a sexual life different from tradition. When one works on the principle that by their works you shall know them, I am happy to commend this book to all who are troubled by the present debate and want to get to grips with it, and understand its history and where we need to go.
