When he had once resolved on a course, he pursued it unflinchingly; he jealously exacted all the honour due to the rank at which he had arrived, defending it as though it were a conquest; he also insisted on enforcing all his legal rights, and he resented the opposition and angry words of casual opponents with a harshness which made them his lifelong enemies.
The first example which Urbain gave of this inflexibility was in 1620, when he gained a lawsuit against a priest named Meunier.

He caused the sentence to be carried out with such rigour that he awoke an inextinguishable hatred in Meunier's mind, which ever after burst forth on the slightest provocation.
A second lawsuit, which he likewise gained; was one which he undertook against the chapter of Sainte-Croix with regard to a house, his claim to which the chapter, disputed.

Here again he displayed the same determination to exact his strict legal rights to the last iota, and unfortunately Mignon, the attorney of the unsuccessful chapter, was a revengeful, vindictive, and ambitious man; too commonplace ever to arrive at a high position, and yet too much above his surroundings to be content with the secondary position which he occupied.

This man, who was a canon of the collegiate church of Sainte-Croix and director of the Ursuline convent, will have an important part to play in the following narrative.

Being as hypocritical as Urbain was straightforward, his ambition was to gain wherever his name was known a reputation for exalted piety; he therefore affected in his life the asceticism of an anchorite and the self-denial of a saint.
