(1) Whether certain goods are necessary in order to excuse marriage?
(2) Whether those assigned are sufficient?
(3) Whether the sacrament is the principal among the goods?
(4) Whether the marriage act is excused from sin by the aforesaid goods?
(5) Whether it can ever be excused from sin without them?
(6) Whether in their absence it is always a mortal sin?
