Mutatis mutandis?

Mutatis mutandis? Changing of Jurisdictional Theories of Some Hungarian Prelates in the Second Half of the Twelfth and in the First Half of Thirteenth Centuries The present paper aims to analyse the jurisdictional theories of some prelates (Lucas, Job, John and Robert, archbishops of Esztergom, Kalocsa and bishop of Veszprém) who had determining influence on the development of the Hungarian ecclesiastical hierarchy in the second half of the twelfth and the first half of thirteenth centuries. I study whether their transition to other (arch)bishopric seat(s) generated or not any changes in the jurisdictional theories, and if so, how contradictory or consequent they were.
