'The history of the papacy in the early Middle Ages is plagued with conflicting scholarly interpretations of its role, importance, and doctrines. David L. d’Avray has written a masterfully lucid analysis of the first papal letters, papal authority and institutions, and the problems the bishops of Rome faced as they strove to create a universal set of norms for the church.'

'… d’Avray’s book provides important insights for scholars and students of the medieval Church. It shows the importance of the fifth century as a formative period, when papal jurisprudence took shape as the result of the exchange of letters between popes and bishops.'
