The most important thing that I can say in review of this book is that the reader must understand that Keener does not believe in the doctrine of the perspicuity of scripture like say J. Carl Laney. Keener recognizes that scripture was written during the time of a certain culture, and that we need to understand that culture in order to see what scripture is really saying to our context: this is a basic hermeneutical practice that is important to observe as we read scripture. It is true that because of this we must work harder to interpret what's really being said in scripture, and therefore a review like Samuel Chapman's is certainly understandable, but really this is a necessary step in being faithful to the bible.
Keener's basic conclusion is that the bible is decidedly against divorce, but there are exceptions in extreme cases of broken marital vows, and that in these situations the innocent party is certainly free to remarry, and hold offices in the church. This he concludes from extensive study of the relevant scriptures passages and from relevant primary and secondary sources from the first century when the New Testament was written.
For a further and even more extensive look at divorce and remarriage and the issues around it, read Dr. David Instone-Brewer's book 'Divorce and Remarriage: the Social and Literary Context.'
