Monasticism has a special position in the history of pastoral care. It produced innovations in various aspects of pastoral care despite, or more precisely, because of its isolation in legal or social terms from the secular world. The thirteen papers contained in this volume will reveal that there was a great variety in the ways pastoral care continued to be practised by monasticism, depending on time, space, and the nature of each religious order. Adopting a comparative approach, their historical and geographical range of investigation is not limited to medieval Europe but expands to the Americas and even to Japan in the early Modern Age. This volume bases on a conference held on 1 and 2 March 2019 at Okayama University, Japan, as part of the close collaboration between a Japanese research group on Christian/Buddhist religious movements and the Research Project "Monasteries in the High Middle Ages: Innovation Laboratories for European Life Designs and Regulatory Models" of the Saxon and the Heidelberg Academies of Sciences and Humanities, as well as the Research Center for Comparative History of Religious Orders (FOVOG, Dresden).
