In Vol. 37,2, Wilhelm Kohl, who must be the leading authority on the history of the Diocese of Münster, deals with the chapters 'Religious and spiritual life' and 'Property'. The diocese displays a variety of religious observance, which could not even be subdued by Papal efforts at standardization, and which shows itself in the books used for services (ordos, missals etc.) and in the Church's yearly festivals, for example on the Feast of the Diocesan Saint Liudger (who however only became popular in early modern times). Also in a class of its own is the broad listing of the episcopal properties and the many rights attached to them. With this volume, Wilhelm Kohl once again makes a major contribution to basic research in Church History, which is also of supreme interest for other disciplines.
