Table Of ContentThe Medieval Church
The Medieval Church: A Brief History argues for the pervasiveness of the Church  
in every aspect of life in medieval Europe. It shows how the institution of the 
Church attempted to control the lives and behaviour of medieval people, for 
example, through canon law, while at the same time being influenced by popular 
movements like the friars and heresy. 
This fully updated and illustrated second edition offers a new introductory  
chapter on ‘the basics of Christianity’, for students who might be unfamiliar with 
this territory. The book now has new material on some of the key individuals in 
Church history – Benedict of Nursia, Hildegard of Bingen, Bernard of Clairvaux 
and Francis of Assisi – as well as a more comprehensive study throughout of the 
role of women in the medieval Church.
Lynch and Adamo seek to explain the history of the Church as an institution, and 
to explore its all-pervasive role in medieval life. In the course of the thousand 
years covered in this book, we see the members and leaders of the western Church 
struggle with questions that are still relevant today: What is the nature of God? 
How does a Church keep beliefs from becoming diluted in a diverse society? 
What role should the state play in religion? 
The book is now accompanied by a website (www.routledge.com/cw/lynch) with 
textual, visual and musical primary sources making it a fantastic resource for 
students of medieval history.

Preface to the first edition
Christianity is a religion in which historical events (or what are believed to be 
historical events) are important. One source of that conviction was the Old 
Testament, which told of God’s dealings with humanity and with his chosen 
people, the Jews. A second source was the deeply held conviction, which 
Catholic  Christians  defended  against  Gnostic  Christians,  that  Jesus  had  
really been born of a woman, had really lived as a human being, had really 
died on a cross and had really risen from the dead. From the first generation, 
Christians understood themselves in a historical way. The presentation of 
Jesus’s life and teachings was not in philosophical treatises (as it might well 
have been) but in narratives – the gospels – that included place, time, circum-
stances and other elements of history. The history of the movement that 
claimed Jesus as its founder – church history proper – was already being  
written in the late first century with Luke’s Acts of the Apostles. Luke had no 
immediate successors. No church writer in the second or third century com-
posed a history in the strict sense of that term, but many of them recorded 
historical details, including the successions of bishops, the disputes within 
the group over belief, the spread of their religion and the persecutions by  
the Roman authorities. Church history received its first full expression in the 
Ecclesiastical History of Bishop Eusebius of Caesarea (c.260–339), who was 
aware that he was a pioneer in his effort to record the historical growth of the 
church.1
Eusebius had several successors in the fourth and fifth centuries, including 
Socrates, Sozomen, Theodoret and Evagrius, all of whom wrote in Greek.2 
Between the eighth and the fifteenth centuries church histories of many kinds 
– those of monasteries, bishoprics, the papacy, religious orders – proliferated. 
Those historians did not think of themselves as living in what we classify as 
‘the Middle Ages’. Usually, they thought they lived in the sixth and final age 
of human history, which was connected by God’s plan to earlier ages and was 
moving more or less rapidly toward the end of time.3
It  was  in  the  fifteenth  century,  when  Renaissance  humanists  divided 
European history into three parts – ancient, middle and modern – that a  
history of the church in its middle or medieval age (media aetas) could be con-
ceptualised. The humanists’ notion of a middle age was generally a negative
Preface to the first edition  ix
one. They saw the media aetas as a period of darkness and barbarism separat-
ing them from their beloved Rome and Greece. The church of that barbaric 
age shared, in their view, in the crudeness and corruption of the times. The 
debate over the character of the church in the middle period grew hotter  
during the sixteenth century as Catholics, Lutherans, Calvinists, Anglicans 
and others quarrelled about the nature of the church and used historical 
arguments to support their respective views.
The study of the medieval church was born in the sixteenth century and 
has been an enterprise of huge proportions and long duration. It has always 
been and continues to be a multilingual pursuit: the main language of  
intellectual life and religion in the medieval west was Latin and that of the 
Christian east was Greek. Modern scholarship of high quality is produced in 
virtually every European language and some non-European languages as well. 
In an annual bibliography published by the Revue d’histoire ecclésiastique, there 
has been an average of 7,524 entries for the last five years, about 40 per cent 
of which touch on the medieval church.
In view of the mountains of sources and modern scholarship, it may be 
thought presumptuous to write a history of the medieval church in a single 
medium-sized volume. The chief justification I can offer is that I have experi-
enced the need for such a work in my own teaching. Also, I am often asked by 
interested people for something both reliable and manageable to read on the 
medieval church. This book is intended to be an introduction for beginners 
and, to be frank, beginners with neither Latin nor extensive knowledge of 
modern foreign languages. With considerable regret, I have purposely restricted 
footnotes and suggested reading almost entirely to works in English, since I 
wanted to provide interested students with sources and secondary works that 
they could read with profit. In almost every instance, I chose to cite works that 
would be useful to a beginner who wished to pursue a particular topic. If  
students were to read what I included in the ‘Suggested Reading’ and in the 
notes, they would learn a great deal about the medieval church. Some readers 
will miss a more extensive treatment of eastern Christianity or of important 
historical figures. I understand their view, but I had to be selective in my 
choice of topics. I have concentrated on the western church and I have empha-
sised ideas and trends over personalities.
For readers who want different treatments of the history of the medieval 
church, there is no shortage of choices in all sorts of formats and approaches. 
I shall suggest only a few. Williston Walker, Richard Norris, David W. Lotz and 
Robert T. Handy, A History of the Christian Church, 4th edn (New York, 1985), 
cover the entire history of the church in about 750 densely printed pages, of 
which about 200 pages cover the Middle Ages. Generations of students have 
profited from Margaret Deanesly’s The Medieval Church, 590–1500, originally 
published in 1925 and reissued in a ninth edition, reprinted with corrections
