Hello, Mr. (Prof./Dr.) Aversa,
I read with interest your page comparing The Religious Sense by the late Msgr. Luigi Giussani to various papal encyclicals.  As an adherent of Communion and Liberation, I have read The Religious Sense as well as many other texts both by Giussani and his successor, Fr. Julian Carron.
Admittedly, I am neither a theologian nor a philosopher. Â Bearing in mind my limited understanding as a layman, I wanted to write and say that I was not able to detect any contradiction between the writings of Giussani you quoted on the left side of the page and the encyclicals quoted on the right side.
Msgr. Giussani firmly believed in the authority of the Church and in particular that of the Bishop of Rome. Â When for a period of time he was ordered to study in the United States, presumably to get him off the scene in Italy where he was understandably mistrusted by some in the hierarchy, he obeyed and did not return until he was allowed to do so. Â Our regional leader here in the United States meets with the local ordinary once a year to keep him informed of our condition and activities. Â Before Benedict XVI stepped down from the pontificate, we followed his writings alongside those of Giussani, particularly during the Year of Faith.
Msgr. Giussani never questioned the dogmas of the Faith but asks his followers to be radically engaged with all the circumstances of their lives, even the most mundane, to help us understand better what salvation means (Christ as the answer to who I am and the ultimate and definitive response to all the original needs of my heart -- for truth, beauty, justice, love, goodness, etc.). Â He does not oppose Tradition but indifference and tepidity in the face of the Christian claim, namely that God Himself became man, the only reasonable response to which is wonder, amazement, and obedience. Â This is anything but boring, yet many Catholics are obviously bored by their faith (just see their faces at Mass, even when God appears before them on the altar).
In the thought of Msgr. Giussani, the encounter with God, for the poor in spirit, produces an experience of exceptional 'correspondence', as he calls it, with the original needs of the human heart. Â Put one way, the subject recognizes his Creator and Savior, like Peter when he spontaneously said to Jesus, "Depart from me, Lord, for I am a sinful man." Â Giussani's writing does not place Christianity on the same plane as any other religion because he tells us that only the encounter with Jesus Christ (certainly I am not using His Name as a generic placeholder for the Unknown!), either bodily two thousand years ago or today through the Spirit acting in those who are baptized (i.e., the Church), inspires in man this recognition of a presence that responds to him totally, unlike anything else he has ever known. Â He realizes that this man, Jesus, is the one he has been searching for. Â Jesus is the only real answer to his restlessness and dissatisfaction.
Giussani did not want his followers to abandon their faith in the Church but to ask of Jesus, and to prepare daily for, the encounter with Him, and to avoid treating Christianity like a drab and conventional routine.  He ardently believed Christianity is the answer par excellence to the truest and deepest needs of the human person.  The Religious Sense is the first step he asks us to take toward the same conviction; this book is not a complete summary of his thought but the beginning. Â
I just wanted to offer these few points in response to your page. Â Thanks for your time and your website, which is full of interesting material.
God bless you,
David
