When in 1312 Grand returned his clerical opponents had united. His stubbornness and invidiousness earned him the Low German nickname "Fürsate" (Engl. literally: fire-seed(er), "the Firebug"). The provost of Hamburg's Subchapter refused to pay, declaring the donum to be illegal, the suffragan prince-bishops of Lübeck, of Ratzeburg, and of Schwerin assented to that view. In 1313 Clement V adjudicated Grand the subsidium caritativum from Hamburg's Subchapter, but it still refused to pay. Grand in return inflicted excommunications on his opponents. The clergy again ignored the excommunications.
