Rendu was very mindful of the manner of receiving the poor. Her spirit of faith saw in them our "lords and masters." "The poor will insult you. The ruder they are; the more dignified you must be," she said. "Remember, Our Lord hides behind those rags." One of Rendu's companions remarked that, "the poor themselves noted her way of praying and acting." "Humble in her authority, Sr. Rosalie would correct us with great sensitivity and had the gift of consoling. Her advice, spoken justly and given with all her affection, penetrated souls."
