Clerical celibacy has been an ideal already since the Apostolic Age, however before the Gregorian Reform no one made any attempts to enforce it, except for several bishops deeply concerned about the condition of the Church. The fight for clerical celibacy actually began with the activities of the 11th-century popes: not only Gregory VII, but also his predecessors issued provisions aimed at introducing the obligatory celibacy for the clergy. These regulations were adopted in Poland and other Central European countries with a considerable delay. Local priests often expressed their resistance and tried to avoid separation with their wives, concubines, and families. It is the main object of the current paper to examine the reception of the imposed standards of clerical celibacy by the society of medieval Poland, with a special emphasis of the priests and their families, who did not always intend to adapt to these new standards obediently.
In this paper, we aim to elucidate some historiographical approaches regarding the Church in Kievan Rus’, particularly during the 11th century. We seek to analyze the ways that the specialized bibliography, both classic/modern and Russian/Western, addresses the subject in social, institutional, and cultural aspects. Finally, we attempt to contribute to the current state of said historiography by using theoretical considerations from authors such as Dominique Iogna-Prat, Michel Lauwers, and Leandro Rust, specialists in Western Church History who seek to approach the ecclesial system from the socio-institutional perspective of the ‘Ecclesiology’, and how such views can corroborate the understanding of the Church of Rus’.
