The medieval church

"The main subjects of enquiry in this volume centre around the major areas in which the honoree, Gordon Leff, has made fundamental contributions. These include learned and popular heresy (Cathars, Wyclif, Lollardy, and the concept of heresy itself); the history of medieval universities and thought (featuring the religious at Paris and Cambridge, Ockham, and Paris theologians' views on the Jews); later medieval religious, and early modern views of the crusades. The book is completed with a bibliography of works by Gordon Leff."--Jacket.
