The chance of Jesus is to be born before Freud. Because imagine for a moment that the reading grid of psychoanalysis is applied to the character described by the Gospels. What to think of a quidam who claims to anyone who will listen: "The Father is in me and I am in the Father"? What would you say if your neighbor came knocking at your door to inform you that “he who eats my flesh and drinks my blood has eternal life”? Was Jesus mad? Based on the Gospels, the author follows this self-proclaimed "son of God" in his deeds and words and discovers that he can be diagnosed as "megaparanoid", that is to say a paranoid producing mythical projections. But the difficulty increases a notch when we know that Jesus has fascinated ever larger crowds over countless generations. From where these other questions: of which psychic disease were struck those which believed it? How was this love between madmen possible, between a megaparanoid shepherd and those he rightly called his sheep?
