Attracted by the ecumenical spirit of Chevetogne Abbey, where, as a young priest, he had become a disciple of Dom Lambert Beauduin, Dom Bruno had, over the years, requested a release from the Mont-César community in order to join the monks at Chevetogne. That request had been repeatedly denied by his abbot. Finally, in 1968, his wish was granted. His final active assignment was as vicar in the town of Ottignies near Louvain where he ministered to the aged, the sick, and the handicapped.
