Dominum et Vivificantem: On the Holy Spirit in the Life of the Church and the World
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," 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." 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."
