Guy de Ventadour
Guy de Lévis de Ventadour (c. 1302–1352) was a French prelate from a family rich in bishops. He became bishop of Cambrai in 1342 and found a diocese in crisis, where many priests ignored the duty to reside in their parishes and left poorly trained substitutes, called deservitors, in their place.
In 1345 he issued a statute ordering the deservitors to present themselves to him on pain of excommunication, and allowing priests to leave their parishes only with his permission. The reform did not last.
Transferred to the see of Vabres in 1349, he soon saw the Cambrai chapter undo his measures. He remained bishop of Vabres until his death in 1352.
