The cardinal trusted him, and therein found his advantage.
There are many stories related of him, and among them this.

After a wild youth, he had retired into a convent, there to expiate, at least for some time, the follies of adolescence.

On entering this holy place, the poor penitent was unable to shut the door so close as to prevent the passions he fled from entering with him.

He was incessantly attacked by them, and the superior, to whom he had confided this misfortune, wishing as much as in him lay to free him from them, had advised him, in order to conjure away the tempting demon, to have recourse to the bell rope, and ring with all his might.

At the denunciating sound, the monks would be rendered aware that temptation was besieging a brother, and all the community would go to prayers.
This advice appeared good to the future chancellor.
