Confronting fictional narrative writing and transcendence thanks to the metamorphosis that the novelist Georges Bernanos had been subjecting his work to for its twenty years’ development requires a threefold critical approach: generic, genetic, hermeneutic. The generic study makes it clear how the eight narrations are challenged to integrate a theological, metaphysical and mystical concept in a fictional setting with a non-reductive novel. Genetic analysis is pointing out a metamorphosis’s topography and timeline of the writing in the corrected crossed-out hand-written page, and in the completed fiction work, not to mention the homogeneous self-block consisting in the scriptural and structural unit of a novel. The hermeneutic investigation reveals the two preferred deployment means of this writing: the Bible as textual transcendence and the Christian mystical adventure as incarnate transcendence.
