Catherine de Saint-Augustin said that Brébeuf appeared to her in a vision at the Québec Hôtel-Dieu while she was in a state of "mystical ecstasy," and he acted as her spiritual advisor. According to one account, Catherine de Saint-Augustin ground up part of Brébeuf's relic bone and gave it in a drink to a heretical and mortally ill man. It is said that the man was cured of his disease. In another instance, in 1660–61, a possessed woman was exorcised by the aid of one of Brébeuf's ribs, again while under the care of Catherine de Saint-Augustin. The exact circumstances of this event are disputed. Brébeuf's relics were also used by nuns who were treating wounded Huguenot (Protestant) soldiers, and they "reported that his assistance slivers put in soldiers' drinks helped rescue these patients from heresy".
