Eric E. Hall takes up the question of the meaning of a term frequently used at present: authenticity and the pursuit of personal originality. By the use of this idea within three contexts - the ethical, the ontological and the theological - investigated, discovered the author the origin and implications of authenticity. To the extent that such authenticity seeks freedom from social horizons in all contexts, it is demonstrated that it is impossible to embody this ideal secular. This objective requires full coming transcendence that can only reach the Divine. Human authenticity is thus derived from the creative imitation of God's self-sacrificial acts of expression on the cross, which both exceed the horizon of this world as well as revalued.
