"Bishops in partibus" refers to Catholic bishops who hold the title of a diocese that is no longer located in its original territory. The word "partibus" is pronounced as /pɑːrˈtiːbʊs/ in IPA phonetic transcription. The "par" is pronounced as in "park," the "ti" is pronounced as in "tea," the "bu" is pronounced as in "book," and the "s" is pronounced as in "sun." The spelling of the word reflects its Latin origin and is commonly used in Catholic canon law.
Bishops in partibus is a Latin term that translates to "Bishops in partibus infidelium" meaning "in the parts of the unbelievers." It refers to a title given to Catholic bishops who are appointed to dioceses or sees that no longer exist due to historical circumstances, such as conquest or religious conversion.
The term originated during the Middle Ages when Muslim invaders conquered various predominantly Christian regions, leading to the suppression or elimination of the local dioceses. Consequently, the pope appointed bishops to these non-existent dioceses as a symbolic representation of the Church's authority and influence in those regions, even though the bishops could not exercise any pastoral duties there.
The bishops in partibus were responsible for maintaining the episcopal succession and preserving the diocesan structure of these non-functioning territories. They are considered titular bishops, meaning they hold a title of a bishopric without any corresponding jurisdiction. As such, they generally do not have a physical diocese to oversee, but they may be assigned to assist in functioning dioceses or serve duties within the Vatican.
The title of bishop in partibus is mostly honorary and reflects historical ties and recognition of the impact of Christianity in specific regions, even if the local Christian communities are no longer present. It represents a link between the present-day Church and its historical roots, signifying continuity and exemplifying the bishops' connection to their predecessors who originally governed those now-defunct dioceses.
