3. The Holy Spirit in Man's Inner Conflict: "For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh"

55. Unfortunately, the history of salvation shows that God's coming close and making himself present to man and the world, that marvelous "condescension" of the Spirit, meets with resistance and opposition in our human reality. How eloquent from this point of view are the prophetic words of the old man Simeon who, inspired by the Spirit, came to the Temple in Jerusalem, in order to foretell in the presence of the new-born Babe of Bethlehem that he "is set for the fall and rising of many in Israel, for a sign of contradiction."²³² Opposition to God, who is an invisible Spirit, to a certain degree originates in the very fact of the radical difference of the world from God, that is to say in the world's "visibility" and "materiality" in contrast to him who is "invisible" and "absolute Spirit"; from the world's essential and inevitable imperfection in contrast to him, the perfect being. But this opposition becomes conflict and rebellion on the ethical plane by reason of that sin which takes possession of the human heart, wherein "the desires of the flesh are against the Spirit and the desires of the Spirit are against the flesh."²³³ Concerning this sin, the Holy Spirit must "convince the world," as we have already said.

It is St. Paul who describes in a particularly eloquent way the tension and struggle that trouble the human heart. We read in the Letter to the Galatians: "But I say, walk by the Spirit, and do not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh; for these are opposed to each other, to prevent you from doing what you would."²³⁴ There already exists in man, as a being made up of body and spirit, a certain tension, a certain struggle of tendencies between the "spirit" and the "flesh." But this struggle in fact belongs to the heritage of sin, is a consequence of sin and at the same time a confirmation of it. This is part of everyday experience. As the Apostle writes: "Now the works of the flesh are plain: fornication, impurity, licentiousness... drunkenness, carousing and the like." These are the sins that could be called "carnal." But he also adds others: "enmity, strife, jealousy, anger, selfishness, dissension, party spirit, envy."²³⁵ All of this constitutes the "works of the flesh."

But with these works, which are undoubtedly evil, Paul contrasts "the fruit of the Spirit," such as "love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control."²³⁶ From the context it is clear that for the Apostle it is not a question of discriminating against and condemning the body, which with the spiritual soul constitutes man's nature and personal subjectivity. Rather, he is concerned with the morally good or bad works, or better the permanent dispositions - virtues and vices - which are the fruit of submission to (in the first case) or of resistance to (in the second case) the saving action of the Holy Spirit. Consequently the Apostle writes: "If we live by the Spirit, let us also walk by the Spirit."²³⁷ And in other passages: "For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit"; "You are in the Spirit, if in fact the Spirit of God dwells in you."²³⁸ The contrast that St. Paul makes between life "according to the Spirit" and life "according to the flesh" gives rise to a further contrast: that between "life" and "death." "To set the mind on the flesh is death, but to set the mind on the Spirit is life and peace"; hence the warning: "For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body you will live."²³⁹

Properly understood, this is an exhortation to live in the truth, that is, according to the dictates of an upright conscience, and at the same time it is a profession of faith in the Spirit of truth as the one who gives life. For the body is "dead because of sin, but your spirits are alive because of righteousness." "So then, brethren, we are debtors, not to the flesh, to live according to the flesh."²⁴⁰ Rather we are debtors to Christ, who in the Paschal Mystery has effected our justification, obtaining for us the Holy Spirit: "Indeed, we have been bought at a great price."²⁴¹

In the texts of St. Paul there is a superimposing - and a mutual compenetration - of the ontological dimension (the flesh and the spirit), the ethical (moral good and evil), and the pneumatological (the action of the Holy Spirit in the order of grace). His words (especially in the Letters to the Romans and Galatians) enable us to know and feel vividly the strength of the tension and struggle going on in man between openness to the action of the Holy Spirit and resistance and opposition to him, to his saving gift. The terms or poles of contrast are, on man's part, his limitation and sinfulness, which are essential elements of his psychological and ethical reality; and on God's part, the mystery of the gift, that unceasing self-giving of divine life in the Holy Spirit.- Who will win? The one who welcomes the gift.

56. Unfortunately, the resistance to the Holy Spirit which St. Paul emphasizes in the interior and subjective dimension as tension, struggle and rebellion taking place in the human heart, finds in every period of history and especially in the modern era its external dimension, which takes concrete form as the content of culture and civilization, as a philosophical system, an ideology, a program for action and for the shaping of human behavior. It reaches its clearest expression in materialism, both in its theoretical form: as a system of thought, and in its practical form: as a method of interpreting and evaluating facts, and likewise as a program of corresponding conduct. The system which has developed most and carried to its extreme practical consequences this form of thought, ideology and praxis is dialectical and historical materialism, which is still recognized as the essential core of Marxism.

In principle and in fact, materialism radically excludes the presence and action of God, who is spirit, in the world and above all in man. Fundamentally this is because it does not accept God's existence, being a system that is essentially and systematically atheistic. This is the striking phenomenon of our time: atheism, to which the Second Vatican Council devoted some significant pages.²⁴² Even though it is not possible to speak of atheism in a univocal way or to limit it exclusively to the philosophy of materialism, since there exist numerous forms of atheism and the word is perhaps often used in a wrong sense, nevertheless it is certain that a true and proper materialism, understood as a theory which explains reality and accepted as the key-principle of personal and social action, is characteristically atheistic. The order of values and the aims of action which it describes are strictly bound to a reading of the whole of reality as "matter." Though it sometimes also speaks of the "spirit" and of "questions of the spirit," as for example in the fields of culture or morality, it does so only insofar as it considers certain facts as derived from matter (epiphenomena), since according to this system matter is the one and only form of being. It follows, according to this interpretation, that religion can only be understood as a kind of "idealistic illusion," to be fought with the most suitable means and methods according to circumstances of time and place, in order to eliminate it from society and from man's very heart.

It can be said therefore that materialism is the systematic and logical development of that resistance" and opposition condemned by St. Paul with the words: "The desires of the flesh are against the Spirit." But, as St. Paul emphasizes in the second part of his aphorism, this antagonism is mutual: "The desires of the Spirit are against the flesh." Those who wish to live by the Spirit, accepting and corresponding to his salvific activity, cannot but reject the internal and external tendencies and claims of the "flesh," also in its ideological and historical expression as anti-religious "materialism." Against this background so characteristic of our time, in preparing for the great Jubilee we must emphasize the "desires of the spirit," as exhortations echoing in the night of a new time of advent. at the end of which, like two thousand years ago, "every man will see the salvation of God."²⁴³ This is a possibility and a hope that the Church entrusts to the men and women of today. She knows that the meeting or collision between the "desires against the spirit" which mark so many aspects of contemporary civilization, especially in some of its spheres, and "the desires against the flesh," with God's approach to us, his Incarnation, his constantly renewed communication of the Holy Spirit - this meeting or collision may in many cases be of a tragic nature and may perhaps lead to fresh defeats for humanity. But the Church firmly believes that on God's part there is always a salvific self-giving, a salvific coming and, in some way or other, a salvific "convincing concerning sin" by the power of the Spirit.

57. The Pauline contrast between the "Spirit" and the "flesh" also includes the contrast between "life" and "death." This is a serious problem, and concerning it one must say at once that materialism, as a system of thought, in all its forms, means the acceptance of death as the definitive end of human existence. Everything that is material is corruptible, and therefore the human body (insofar as it is "animal") is mortal. If man in his essence is only "flesh," death remains for him an impassable frontier and limit. Hence one can understand how it can be said that human life is nothing but an "existence in order to die."

It must be added that on the horizon of contemporary civilization - especially in the form that is most developed in the technical and scientific sense - the signs and symptoms of death have become particularly present and frequent. One has only to think of the arms race and of its inherent danger of nuclear self-destruction. Moreover, everyone has become more and more aware of the grave situation of vast areas of our planet marked by death-dealing poverty and famine. It is a question of problems that are not only economic but also and above all ethical. But on the horizon of our era there are gathering ever darker "signs of death": a custom has become widely established - in some places it threatens to become almost an institution - of taking the lives of human beings even before they are born, or before they reach the natural point of death. Furthermore, despite many noble efforts for peace, new wars have broken out and are taking place, wars which destroy the lives or the health of hundreds of thousands of people. And how can one fail to mention the attacks against human life by terrorism, organized even on an international scale?

Unfortunately, this is only a partial and in complete sketch of the picture of death being composed in our age as we come ever closer to the end of the second Millennium of the Christian era. Does there not rise up a new and more or less conscious plea to the life-giving Spirit from the dark shades of materialistic civilization, and especially from those increasing signs of death in the sociological and historical picture in which that civilization has been constructed? At any rate, even independently of the measure of human hopes or despairs, and of the illusions or deceptions deriving from the development of materialistic systems of thought and life, there remains the Christian certainty that the Spirit blows where he wills and that we possess "the first fruits of the Spirit," and that therefore even though we may be subjected to the sufferings of time that passes away, "we groan inwardly as we wait for...the redemption of our bodies,"²⁴⁴ or of all our human essence, which is bodily and spiritual. Yes, we groan, but in an expectation filled with unflagging hope, because it is precisely this human being that God has drawn near to, God who is Spirit. God the Father, "sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh."²⁴⁵ At the culmination of the Paschal Mystery, the Son of God, made man and crucified for the sins of the world, appeared in the midst of his Apostles after the Resurrection, breathed on them and said, "Receive the Holy Spirit." This "breath" continues forever, for "the Spirit helps us in our weakness."²⁴⁶
