This book is a good lay-level primer on the doctrine of justification.
Though Oden’s ecumenical efforts are laudable, he fails to defend the thesis of this book. There are times he says “justification by grace through faith” — no problem! However, on multiple different occasions he says “faith alone” or appeals to “sola fide” when no doctrinally-sound Catholic would follow him into those waters.
His selection of patristic texts was helpful, though the brevity of many of the quotes did not help his efforts.
Ultimately, I enjoyed this read, but it cannot rise above the level of three stars, for me, due to how insufficient Oden’s handling of his own thesis was.
