As part of his role of Chaplain to the de Gondis, Vincent visited the estates of the de Gondi family. One day in January 1617, he accompanied Mme de Gondi to her chateau in Folleville, in Picardy.  From nearby Gannes, two  leagues away, came the news that a dying peasant wished to see M. Vincent.  Immediately he hurried to the sick man's bedside.  He sat down by the sick man's bed to hear his confession. He urged the man to make a general confession of all the sins of his life. Later the man recounted to Mme de Gondi that he had been carrying heavy burdens all his life which he had never confessed, and might have been damned but for this general confession. As a result, Vincent, a few days later on January 25th at Folleville, preached on the subject of making a general confession, and was amazed at the number of people who responded. The Jesuits had to be called in to help!
