I've enjoyed quite a few of Frank Barlow's books over the years, and always found them not only informative and interesting, but written in a very engaging manner, easy for the student to absorb technical and complex information in a very accessible way.
This book is a vew of the English church up to the Norman Conquest, the eve of the `Gregorian' reform. It is a constitutional history, which does not pretend to cover all aspects of religious history (such as religious thought, and art and archaeology) but works through aspects of the people (king, nobility, church hierarchy), the relationship between the church and the kingdom, the geographical organisation and economy of the church, ecclesiastical government and jurisdiction, education and heritage of the clergy, and relations with the Papacy during the period.
This is a period of great change and development in England historically, and the development of its church is an integral part of that history.
First published in 1963, some of the research may have been superseded by now, or is viewed differently, but this book is still a most refreshing and interesting read. Highly recommended.
