Excellent treatment of a narrow subject: how society shaped the church
Format: Paperback
This book is not a comprehensive overview of the church from 700-1500, nor is it a narrative treatment or an introduction. This book is highly selective, focusing on one central theme. Its strengths are in its organization and in the examples it gives to illustrate its theme. These examples are concrete, vivid and use quotations from original documents to excellent effect.
The theme of the book is how society shaped the church. Southern examines the main institutions of the church -- the papacy, bishops, religious orders and fringe orders -- and shows how the needs and interests of society molded each. Perhaps having written on 1000-1200 in other books, for me, the strongest insights Southern makes here are on the periods 750-1000 and 1200-1500.
Insights that particularly struck me: the importance of magic from 750-1000; the evolution of bishops, from supporting local rulers to supporting the pope; the importance of the Augustinian canons in the twelfth century, seeing them as one end of a pole, with the Cistercians on the other end and the Benedictines in the middle; the role of Franciscans and Dominicans in supporting scholars in the thirteenth century; and the fringe orders -- the book has one of the best treatments of the Brethren of the Common Life from the fourteenth century that I have come across.
The book is highly selective. There is no treatment in this book on intellectual life (the "new learning") or artistic life, nor is there much on the heresies of the period or popular religion (the "new piety"). What the book does select to treat, it does so in a deep, highly readable, substantial way. One will definitely come away with how the demands of society molded the church. Highly recommended!!

Wonderful book, but not a general reference on the subject & period
Format: Paperback
Southern's powerful study of the organizational and administrative structures of the medieval church is a wonderful antidote for the popular view of the Middle Ages as a long period of almost continual chaos between the Fall of the Roman Empire and the Renaissance (i.e. the "Dark Ages"). Southern does a fantastically good job of explaining and illustrating the central truth of the Church in the Middle Ages, i.e. that the Church was identical with society to an extent that had never been true before and has never been true since. That said, Southern's disciplined approach is often too much of a good thing and there are a number of topics which one would expect to take pride of place in a typical narrative history of the subject and period that Southern touches on only obliquely and insofar as they are relevant to his primary topic: those neglected stories include the long papal/imperial struggle (Guelps & Ghibellines), the Crusades, the Black Death, etc.. Southern also has a puzzling and sometimes maddening tendency to couch the discussion in terms of implications, roles and epithets instead of being explicit and just naming names. E.g. in the context of the discussion of the fall of Constantinople, Mehmed II is mentioned äs "the conqueror", but not by name; that a pope visited Constantinople in 710 for the first time and last time in premodern history is noted, but the pope is not named (it was Constantine); some of consequences of the "Donation of Constantine" are implied fairly early in the book, but it is not explitly named (and then, to add to the reader's irritation, discussed later as if the topic had already been explitly introduced). These are all characteristic slips of an expert used to addressing other experts in his field attempting in this instance to write a more or less introductory text. They are understandable slips, but they take their toll. The book is generally excellent & well worth reading and it is hard to imagine a better introduction to the topics it does cover, but unfortunately, and unlike Chadwick's initial volume in this series, it does not serve well as a general reference on the history of the Medieval Church.

Concise
Format: Paperback
I recently discovered how little I know about my own faith. This book is the second in a series of Penguin books on the history of the church. The author does an excellent job of providing an overview of the social setting of the middle ages and how the papacy, the East-West schism and the religious orders developed during this time period. I recommend this book to anyone who wants to understand more about how we got to where we are.

Sad to say Christians killed "infidels" too
Format: Paperback
A real eye-opener! Christians were killing "infidels" in the middle ages and the infidels were other Christians, Jews and Muslims.
