Spe Salvi Part 25 - Pope Benedict XVI

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.
