Abstract: Its founder had placed the order of Bethany under the patronage of Mary Magdalene, convinced that the contagion of purity could overcome the infectiousness of evil. The figure of the holy sinner is present in Giraudoux’s work, with themes like obsession with defilement, grace, and reversibility. While he seems to be getting closer to the faith of his childhood, he rediscovers in Le Film de Béthanie their spiritual origin, while superimposing the path of souls predestined for each other.
