He would have given him the Abbey of Bourgueil, or of Sanct Florent, which was better, or both, if it pleased him; but the monk gave him a very peremptory answer, that he would never take upon him the charge nor government of monks.
Both the Abbey of Bourgueil and Saint-Florent are Benedictine abbeys/monasteries. This correlates with Rabelais' own previous occupation as a Benedictine monk. This own inclusion goes along with other medical and anatomical mentions. Religion is a great topic that reoccurs within this reading, and I think that including something that is also a part of himself as a person and not just "the author" is a great way of making a piece of writing more person to one's self.
Although being part of a Benedictine order, Rabelais had been a part of a humanistic movement, emphasizing human potential and the freedom to pursue human nature. This type of theme can definitely be seen within his writing despite sticking to specific viewpoints.
