When I was about a third of the way through, I was tempted to give up on this book, as I wasn't certain where the Author was going. Whilst there were many well written, and even thought-provoking, passages for me they seemed disjoint. However about halfway through this small book things things seem to gel. I became quite engage with the Author's examination of Figural Reading and Ecclesial Practices.
As expected in a "Companion" book, there are many good references in the final chapter - with explanation. And a nice bibliography for further study.
So whilst it started off poorly (in my opinion, and I fully acknowledge the fault may lie with me), I did end up enjoying where the book went :)
