This is a fascinating book covering the history behind the various confessional documents that make up the Lutheran Book of Concord. Thus it covers the Ecumenical Creeds (Apostles, Nicene and Athanasian), Luther’s Small and Large Catechisms, Augsburg Confession, Apology of the Augsburg Confession, Smalcald Articles and the Formula of Concord. Whilst I had a reasonable knowledge of the history of the creeds, and of the history of Luther’s life, I must admit I found much that I didn’t know (or hadn’t properly taken on board) when it came to the roughly 25 years following Luther’s Death. Plus it is nice to have all these histories in one place, and nicely connected. I felt the authors did a fair job when it came to examining both those for and against the various documents, as well as looking at the situations that motivated the documents. This is also a good book to get a feel for the history of the Lutheran Church in the 16th Century - as opposed to a history of Luther - and I think I was better versed in the latter than the former, so I welcomed my journey with this book.
