In The Religious Sense
(the first in his trilogy), Giussani demonstrates how reason, in its faithfulness to its original dynamic openness to the totality of reality, always comes to a point where it collides with Mystery (if indeed it is faithful to its impulse). In At the Origin of the Christian Claim
, the second book of the trilogy, Giussani delves into Mystery, revealing itself -- the great personal self-revelation of God in the world in the person of Jesus Christ. How this event draws the attention of men, how Jesus brought about a clear conviction in those who began to follow him, in what way he communicated the mystery of his person, how he confirmed his self-revelation in a new and perfect understanding of the human person -- these are the rich trajectories pursued in this book. (The trilogy concludes with Why the Church?.)
An Eighth Day View:
Giussani argues that if we accept the hypothesis that the mystery entered the realm of human existence and spoke in human terms, the relationship between the individual and God is no longer based on a moral, imaginative, or aesthetic human effort but instead on coming upon an event in one's life. Thus the religious method is overturned by Christ: in Christianity it is no longer the person who seeks to know the mystery but the mystery that makes himself known by entering history. At the Origin of the Christian Claim presents an intriguing argument supported with ample documentation from the gospels and other theological writings.
