The text of his address, via Zenit, follows, with my emphases and comments:
Today I would like to continue reflecting on how prayer and the religious sense have been a part of mankind throughout history.
We live in an age in which the signs of secularism are evident. It seems that God has disappeared from the horizon of many persons or that he has become a reality before which one remains indifferent. However, at the same time we see many signs that indicate to us an awakening of the religious sense, a rediscovery of the importance of God for man's life, a need of spirituality, of surmounting a purely horizontal, material vision of human life. Analyzing recent history, the prediction has failed of those who in the age of the Enlightenment proclaimed the disappearance of religions and exalted absolute reason, separated from faith, a reason that would have dispelled the darkness of religious dogmas and dissolved "the world of the sacred," restoring to man his liberty, his dignity and his autonomy from God. The experience of the last century, with the two tragic World Wars, put in crisis that progress that autonomous reason, man without God, seemed to be able to guarantee.
The Catechism of the Catholic Church affirms: "In the act of creation, God calls every being from nothingness into existence. [...] Even after losing through his sin his likeness to God, man remains an image of his Creator, and retains the desire for the one who calls him into existence. All religions bear witness to men's essential search for God" (No. 2566). We could say -- as I showed in the previous catechesis -- that there has been no great civilization, from the most ancient times up to our days, which has not been religious.
Man is religious by nature, he is homo religiosus as he is homo sapiens and homo faber [maker]. "The desire for God," the Catechism also affirms, "is written in the human heart, because man is created by God and for God" (No. 27). The image of the Creator is imprinted in his being and he feels the need to find a light to give an answer to the questions that have to do with the profound meaning of reality; an answer that he cannot find in himself, in progress, in empirical science. Homo religiosus does not emerge only from the ancient world, but he crosses the whole history of humanity.
To this end, the rich terrain of human experience has witnessed the emergence of different forms of religiosity, in the attempt to respond to the desire for plenitude and happiness, to the need of salvation, to the search for meaning. "Digital" man and the caveman alike seek in religious experience the ways to overcome his finitude and to ensure his precarious earthly adventure. Moreover, life without a transcendent horizon would not have complete meaning, and the happiness to which we tend, is projected toward a future, toward a tomorrow that is yet to be attained.
In the declaration "Nostra Aetate," the Second Vatican Council stressed it synthetically. It states: Men expect from the various religions answers to the unsolved riddles of the human condition, which today, even as in former times, deeply stir the hearts of men: What is man? What is the meaning, the aim of our life? What is moral good, what sin? Whence suffering and what purpose does it serve? Which is the road to true happiness? What are death, judgment and retribution after death? What, finally, is that ultimate inexpressible mystery which encompasses our existence: whence do we come, and where are we going?" (No. 1). Man knows that he cannot answer on his own his fundamental need to understand. Even if he is deluded and still believes that he is self-sufficient, he has the experience that he is not sufficient unto himself. He needs to open himself to the other, to something or someone, which can give him what he lacks, he must come out of himself toward the One who can fill the extent and profundity of his desire.
Man bears within himself a thirst for the infinite, a nostalgia for eternity, a search for beauty, a desire for love, a need for light and truth, which drive him toward the Absolute; man bears within himself the desire for God. And man knows, in some way, that he can address himself to God, that he can pray to him. St. Thomas Aquinas, one of the greatest theologians of history, defines prayer as the "expression of man's desire for God." This attraction toward God, which God himself has placed in man, is the soul of prayer, which is cloaked in many forms and modalities according to the history, time, moment, grace and finally the sin of each one of those who pray. In fact, man's history has known varied forms of prayer, because he has developed different modalities of openness toward the on High and toward the Beyond, so much so that we can recognize prayer as an experience present in every religion and culture.
In fact, dear brothers and sisters, as we saw last Wednesday, prayer is not linked to a particular context, but is found inscribed in every person's heart and in every civilization.
Of course, when we speak of prayer as man's experience in as much as man, of the homo orans [prayer], it is necessary to keep in mind that this is an interior attitude, rather than a series of practices and formulas, a way of being before God, rather than carrying out acts of worship or pronouncing words. Prayer has its center and founds its roots in the most profound being of the person; that is why it is not easily decipherable and for the same reason, it can be subject to misunderstandings and mystifications. Also in this sense we can understand the expression: it is difficult to pray. In fact, prayer is the place par excellence of gratuitousness, of the tension towards the Invisible, the Unexpected, the Ineffable. Because of this, the experience of prayer is a challenge for everyone, a "grace" to be invoked, a gift of the One whom we address.
In all the periods of history, in prayer man considers himself and his situation before God, from God and in regard to God, and he experiences himself as being a creature in need of help, incapable of achieving by himself the fulfillment of his existence and his hope. The philosopher Ludwig Wittgenstein reminded that "to pray means to feel that the meaning of the world is outside the world." In the dynamic of this relationship with the One who gives meaning to existence, with God, prayer has one of its typical expressions in the gesture of kneeling. It is a gesture that bears in itself a radical ambivalence: in fact, I can be obliged to kneel -- condition of indigence and slavery -- or I can kneel spontaneously, confessing my limit and, hence, my need for the Other. To Him I confess that I am weak, needy, a "sinner."
In the experience of prayer, the human creature expresses all his awareness of himself, all that he is able to understand of his existence and, at the same time, he addresses himself wholly to the Being before whom he is, he orients his soul to that Mystery from which he awaits the fulfillment of his most profound desires and help to surmount the indigence of his life. In this looking at the Other, in this addressing "the beyond" is the essence of prayer, as experience of a reality that surpasses the sentient and the contingent.
However, the full realization of man's search is found only in the God who reveals himself. Prayer, which is the opening and raising of the heart to God, becomes a personal relationship with Him. And even if man forgets his Creator, the living and true God does not fail to call man to the mysterious encounter of prayer. As the Catechism affirms: "In prayer, the faithful God's initiative of love always comes first; our own first step is always a response. As God gradually reveals himself and reveals man to himself, prayer appears as a reciprocal call, a covenant drama. Through words and actions, this drama engages the heart. It unfolds throughout the whole history of salvation" (No. 2567).
Dear brothers and sisters, let us learn to spend more time before God, let us learn to recognize in silence the God who has revealed himself in Jesus Christ, to recognize in the depth of ourselves his voice that calls us and leads us back to the profundity of our existence, to the fount of life, to the source of salvation, to make us go beyond the limits of our life and to open ourselves to the measure of God, to the relationship with Him who is Infinite Love. Thank you!
