In Ypres he found a diocese where no bishop recognized by the pope had been in power since 1713 as a result of disputes between France, Spain and Pope Clement XI.
Bishop of Ghent
On 1 March 1730 the regent Maria Elisabeth of Austria appointed him bishop of Ghent. On 6 August 1731, his appointment was confirmed by the Pope (Clement XII) and he was installed on 2 March, 1732.[2][4] His motto was Caelestia cude arma.[2]
That same day he was registered in the crossbow archers' guild (foot archers) of Saint George of Ghent.
On 27 September 1741 he died and was interred in the crypt of St Bavo's Cathedral. He was 67 years old.[2][3]
His mausoleum (sculpted by Jacques Bergé)[5] is located against the choir enclosure in the south ambulatory of Saint Bavo's Cathedral, opposite Saint-Gilles Chapel.
