ENCYCLICAL LETTER SPE SALVI OF THE SUPREME PONTIFF BENEDICT XVI
TO THE BISHOPS, PRIESTS AND DEACONS, MEN AND WOMEN RELIGIOUS
AND ALL THE LAY FAITHFUL
ON CHRISTIAN HOPE

21. Together with the victory of the revolution, though, Marx's fundamental error also became evident. He showed precisely how to overthrow the existing order, but he did not say how matters should proceed thereafter. He simply presumed that with the expropriation of the ruling class, with the fall of political power and the socialization of means of production, the new Jerusalem would be realized. Then, indeed, all contradictions would be resolved, man and the world would finally sort themselves out. Then everything would be able to proceed by itself along the right path, because everything would belong to everyone and all would desire the best for one another. Thus, having accomplished the revolution, Lenin must have realized that the writings of the master gave no indication as to how to proceed. True, Marx had spoken of the interim phase of the dictatorship of the proletariat as a necessity which in time would automatically become redundant. This "intermediate phase" we know all too well, and we also know how it then developed, not ushering in a perfect world, but leaving behind a trail of appalling destruction. Marx not only omitted to work out how this new world would be organized—which should, of course, have been unnecessary. His silence on this matter follows logically from his chosen approach. His error lay deeper. He forgot that man always remains man. He forgot man and he forgot man's freedom. He forgot that freedom always remains also freedom for evil. He thought that once the economy had been put right, everything would automatically be put right. His real error is materialism: man, in fact, is not merely the product of economic conditions, and it is not possible to redeem him purely from the outside by creating a favourable economic environment.

22. Again, we find ourselves facing the question: what may we hope? A self-critique of modernity is needed in dialogue with Christianity and its concept of hope. In this dialogue Christians too, in the context of their knowledge and experience, must learn anew in what their hope truly consists, what they have to offer to the world and what they cannot offer. Flowing into this self-critique of the modern age there also has to be a self-critique of modern Christianity, which must constantly renew its self-understanding setting out from its roots. On this subject, all we can attempt here are a few brief observations. First we must ask ourselves: what does "progress" really mean; what does it promise and what does it not promise? In the nineteenth century, faith in progress was already subject to critique. In the twentieth century, Theodor W. Adorno formulated the problem of faith in progress quite drastically: he said that progress, seen accurately, is progress from the sling to the atom bomb. Now this is certainly an aspect of progress that must not be concealed. To put it another way: the ambiguity of progress becomes evident. Without doubt, it offers new possibilities for good, but it also opens up appalling possibilities for evil—possibilities that formerly did not exist. We have all witnessed the way in which progress, in the wrong hands, can become and has indeed become a terrifying progress in evil. If technical progress is not matched by corresponding progress in man's ethical formation, in man's inner growth (cf. Eph 3:16; 2 Cor 4:16), then it is not progress at all, but a threat for man and for the world.

23. As far as the two great themes of "reason" and "freedom" are concerned, here we can only touch upon the issues connected with them. Yes indeed, reason is God's great gift to man, and the victory of reason over unreason is also a goal of the Christian life. But when does reason truly triumph? When it is detached from God? When it has become blind to God? Is the reason behind action and capacity for action the whole of reason? If progress, in order to be progress, needs moral growth on the part of humanity, then the reason behind action and capacity for action is likewise urgently in need of integration through reason's openness to the saving forces of faith, to the differentiation between good and evil. Only thus does reason become truly human. It becomes human only if it is capable of directing the will along the right path, and it is capable of this only if it looks beyond itself. Otherwise, man's situation, in view of the imbalance between his material capacity and the lack of judgement in his heart, becomes a threat for him and for creation. Thus where freedom is concerned, we must remember that human freedom always requires a convergence of various freedoms. Yet this convergence cannot succeed unless it is determined by a common intrinsic criterion of measurement, which is the foundation and goal of our freedom. Let us put it very simply: man needs God, otherwise he remains without hope. Given the developments of the modern age, the quotation from Saint Paul with which I began (Eph 2:12) proves to be thoroughly realistic and plainly true. There is no doubt, therefore, that a "Kingdom of God" accomplished without God—a kingdom therefore of man alone—inevitably ends up as the "perverse end" of all things as described by Kant: we have seen it, and we see it over and over again. Yet neither is there any doubt that God truly enters into human affairs only when, rather than being present merely in our thinking, he himself comes towards us and speaks to us. Reason therefore needs faith if it is to be completely itself: reason and faith need one another in order to fulfil their true nature and their mission.

24. Let us ask once again: what may we hope? And what may we not hope? First of all, we must acknowledge that incremental progress is possible only in the material sphere. Here, amid our growing knowledge of the structure of matter and in the light of ever more advanced inventions, we clearly see continuous progress towards an ever greater mastery of nature. Yet in the field of ethical awareness and moral decision-making, there is no similar possibility of accumulation for the simple reason that man's freedom is always new and he must always make his decisions anew. These decisions can never simply be made for us in advance by others—if that were the case, we would no longer be free. Freedom presupposes that in fundamental decisions, every person and every generation is a new beginning. Naturally, new generations can build on the knowledge and experience of those who went before, and they can draw upon the moral treasury of the whole of humanity. But they can also reject it, because it can never be self-evident in the same way as material inventions. The moral treasury of humanity is not readily at hand like tools that we use; it is present as an appeal to freedom and a possibility for it. This, however, means that:

a) The right state of human affairs, the moral well-being of the world can never be guaranteed simply through structures alone, however good they are. Such structures are not only important, but necessary; yet they cannot and must not marginalize human freedom. Even the best structures function only when the community is animated by convictions capable of motivating people to assent freely to the social order. Freedom requires conviction; conviction does not exist on its own, but must always be gained anew by the community.

b) Since man always remains free and since his freedom is always fragile, the kingdom of good will never be definitively established in this world. Anyone who promises the better world that is guaranteed to last for ever is making a false promise; he is overlooking human freedom. Freedom must constantly be won over for the cause of good. Free assent to the good never exists simply by itself. If there were structures which could irrevocably guarantee a determined—good—state of the world, man's freedom would be denied, and hence they would not be good structures at all.

25. What this means is that every generation has the task of engaging anew in the arduous search for the right way to order human affairs; this task is never simply completed. Yet every generation must also make its own contribution to establishing convincing structures of freedom and of good, which can help the following generation as a guideline for the proper use of human freedom; hence, always within human limits, they provide a certain guarantee also for the future. In other words: good structures help, but of themselves they are not enough. Man can never be redeemed simply from outside. Francis Bacon and those who followed in the intellectual current of modernity that he inspired were wrong to believe that man would be redeemed through science. Such an expectation asks too much of science; this kind of hope is deceptive. Science can contribute greatly to making the world and mankind more human. Yet it can also destroy mankind and the world unless it is steered by forces that lie outside it. On the other hand, we must also acknowledge that modern Christianity, faced with the successes of science in progressively structuring the world, has to a large extent restricted its attention to the individual and his salvation. In so doing it has limited the horizon of its hope and has failed to recognize sufficiently the greatness of its task—even if it has continued to achieve great things in the formation of man and in care for the weak and the suffering.
