Another Bishop of the Diocese of Ghent, Belgium had his arms in St. Bavo's Cathedral. At the time we were there (in late 2019), he was still the Bishop, so these arms are certainly more contemporary than historical.
These arms also appear with his portrait:
These are the arms of Lucas van Looy, Bishop of Ghent 2003-2019. My best guess at a blazon would be: Argent four piles reversed [or, inverted] issuant from base and throughout sable on a chief sapiné throughout azure and vert in chief four mullets argent. The motto is: In nomine patris (In the name of the Father.)
