The start of this book made me want to give a single star. His portrayal of the apostolic fathers and some of the early fathers is half-baked, underdeveloped, and over-reliant on the opinion's of secondary sources, which are now quite dated and have been rightly challenged. He nearly concedes the period to his theological opponents (particularly the Roman Catholics). His portrayal of Augustine's eucharistic theology is misinformed and again over-reliant on secondary sources of his era. He lacks insight into Augustine's philosophical presuppositions, and does not read him carefully. The section on the middle ages is a marked improvement, but is nothing to write home about. He broadly covers topics with accuracy, with the occasional misstep, again especially around eucharistology. The Reformation and post-Reformation era are relatively well done, though without enough material covering proto-Protestant figures, and without enough in-depth coverage of post-Reformation controversies. The 18th-19th century is covered far too in-depth for the size of the volume. He wastes ink covering innumerable figures who do not even believe the Bible, apart from seeing it as useful for morals, philosophy, social cohesion, or archetypes. Yet he totally skips over figures from this era that were faithful, such as Hamann, Herder, Pontoppidan, Loescher, Walther, Loehe, etc. His coverage of Christianity outside Europe is abysmal and only gets passing mentions. Overall, a poor treatment of the history of theology. Below a passing grade, though not an absolute failure.
