I bought this book yesterday evening, read it with extreme care and deliberation until past midnight, and picked it up again as soon as I woke up, reading straight through to I finished. Undoubtedly a tour de force of patient ethical reasoning.
However, this book is not four stars. It is either three or five, and for the time being, I have had to say it is four, until I can decide. Minimally it is three stars, because of the outstanding acumen, balance, and sophistication with which O'Donovan tackles all the red herrings, knee-jerk reactions, and false dichotomies that surround this issue. He patiently and thoroughly explores the nature of church unity and authority, Scriptural authority, the liberal agenda, ethical reflection and so on. The book is probably five stars, because I believe the final two chapters, where he begins to get a bit more concrete and to-the-point (though still making mainly methodological points rather than voicing conclusions), are up to the same standard. My own knee-jerk reactions, however, militate against much of what he says, and if they are correct, then it may be true that O'Donovan ends by compromising his argument with relativistic drivel which doesn't know when to call a spade a spade. But I am humble enough to suppose that these reactions are probably not correct. More to come.
*update*
Ok, so I read through the last chapter in, super-slowly. And I think I have to give it five stars. There are, I think, no holes to poke ultimately in what he said. Folks from our background might wish he said more, but he wasn't writing to us, so it's a bit unfair to demand that. Full review should be up on johannulusdesilentio.blogspot.com soon.

Finally finished the full review, 20,000 words long, on johannulusdesilentio.blogspot.com. The verdict remains; excellent book, 5 stars.
