I'm really mixed on this book. I really, really like the premise. Green presents a really strong case for the Petrine voice as the dominant strain that lies behind the NT writings (Gospels and letters). I am nearly entirely convinced of his position, and thus this remains a crucial piece of theology regarding this aspect of Chrsitian history, our understanding of the text, and our view of history. His basic case rests on a familiar assertation to anyone who has spent time with writers within the New Perspecctive (on Paul), which is that the Protestant tendency to elevate Paul as Christendom's core figure and voice has come at the expense of much. Usually that focuses on how it has tended to relegate the Gospels themsleves to the shadows of our Pauline "theologies", which then misses the Gospels while misunderstanding Paul outside of his own Gospel context. Green takes this same reasoning to another step yet, which is to establish the claim that in relegating the Gospel's to the shadow's of Paul we have equally lost sight of Peter, leading to a clear absence of scholarship around Peter, and similarly the absence of a clear Vox Petri (theology or voice of Peter). Peter gets relegated to a function of the Pauline narratve rather than having any historical force himself.
This is, as Green would suggest, important and even crucial because of the degree to which Peter stands behind Mark, which then gives shape to the other Gospel Traditions as part of an existing "conversataion", a conversation that then bleeds into the Acts of the Apostles and the letters with prevelance and relevance. We, then, need to recalibrate our understanding of the text by stepping back and begining with Peter before moving outwards into the larger picture in order to understand what is going on with this conversation.
As I said, it's a strong premise, and almost entirely convincing (to me). If I had a critique of this book though its that it should have been a whole lot shorter. And it's not a long book to begin with. The real problem is that in making his case in the first few chapters, Green then uses the buik of the rest of the book to actually go through this process of beginning with the Gospel of Mark and then working through each book that contains what he argues to be a definable Vox Petri. The issue is that these treatments are clearly limited in their scope, even in larger parts devolving into devotional like territory (replete with his own theological assumptions and Tradition). That's not necessarily bad in and of itself, but it also doesn't take long to see the repitition. He could have established the same point in a single sentence that applies to all of the material he is walking through book by book. This kind of muddles what precisely this book is, and undermiines a bit its scholarly focus on a historical level, which is actually what I wanted more of. He had me, and I was ready to be taken even deeper into this premise. Instead all of the time spent on each book keeps our head relatively above water, giving time to stuff I had to wade through hoping to get back to the stuff of the first few chapters, which it never really does (outside of a nice final summary that connects the book by book summary to the first few chapters. That was stong).
In any case, I strongly recommend the first few chapters of this book. Less so the rest of it. Overall though I found it worth my time to open up a door I hadn't given much thought to before.
