The book is well written, accessible, and "lege artis" historically. But it is written entirely from the human perspective: humans invented the Jewish history, humans wrote the bible, humans invented the christian religion, and humans are quarreling about its details. If you are looking for religious inspiration, I would definitely not recommend reading this book. But it does put those details which have been subject to so much discussion in the past centuries in a broader perspective, which can make it easier to accept different christian denominations as brothers and sisters.
This is a very comprehensive history of the development of Christianity. The reader will probably have heard of and know something about the major players mentioned, but there are a great number of until now obscure characters who have walk-on parts. It is almost more of an encyclopedia than a narrative. Great as a reference work, but a long slog through a thousand pages.
The writer has a deep knowledge of this vast subject. His book is meticulously researched and beautifully written. Despite the intimidating length, I'm enjoying every page and already (halfway through) amd sad to know this wonderful read will end.
