God, I heard his voice, not from outside or above, but from within me. God's true voice always comes to us from within. (Kazantazakis 56)
Scorsese's Jesus marked the inward turn toward a privatized, expressive indicualism that increasingly marked American individualism after 1960... In the process of choosing God (himself?) instead of Mary Magdaline or Judas's politicized religion, Scorsese's Jesus becomes a virtual icon for this late twentieth-century Ameican mythology.
Jesus rejects the social views and positions on God in order to develop his own, personalized view of how the messiah will come. He blatantly rejects the law as "against my heart", and experiences personal revelatory visions in which God tells him what to do. There is a blatant rejection of authority (the equivalent of the Catholic Church) in lieu of the individualized, personal gnosis Jesus experiences about himself, though the knowledge he receives is hardly what is typically seen as the gnostic gospel, full of aeons, monads, dyads, demiurges, etc. the important thing, though, is that the experience Jesus has with God is both individualistic as opposed to social, redactive rather than complementary.
Jesus' transition is one of Individuation, of self-knowledge? Who am I? What is my purpose? Am I man or God?
