Magisterium, Second Vatican Council

33. Through his labours and his native endowments man has ceaselessly striven to better his life. Today, however, especially with the help of science and technology, he has extended his mastery over nearly the whole of nature and continues to do so. Thanks to increased opportunities for many kinds of social contact among nations, the human family is gradually recognizing that it comprises a single world community and is making itself so. Hence many benefits once looked for, especially from heavenly powers, man has now enterprisingly procured for himself.

In the face of these immense efforts which already preoccupy the whole human race, men agitate numerous questions among themselves. What is the meaning and value of this feverish activity? How should all these things be used? To the achievement of what goal are the strivings of individuals and societies heading? The Church guards the heritage of God's word and draws from it moral and religious principles without always having at hand the solution to particular problems. As such she desires to add the light of revealed truth to mankind's store of experience, so that the path which humanity has taken in recent times will not be a dark one.

34. Throughout the course of the centuries, men have laboured to better the circumstances of their lives through a monumental amount of individual and collective effort. To believers, this point is settled: considered in itself, this human activity accords with God's will. For man, created to God's image, received a mandate to subject to himself the earth and all it contains, and to govern the world with justice and holiness;[1] a mandate to relate himself and the totality of things to Him Who was to be acknowledged as the Lord and Creator of all. Thus, by the subjection of all things to man, the name of God would be wonderful in all the earth.[2]

This mandate concerns the whole of everyday activity as well. For while providing the substance of life for themselves and their families, men and women are performing their activities in a way which appropriately benefits society. They can justly consider that by their labour they are unfolding the Creator's work, consulting the advantages of their brother men, and are contributing by their personal industry to the realization in history of the divine plan.[3]

Thus, far from thinking that works produced by man's talent and energy are in opposition to God's power, and that the rational creature exists as a kind of rival to the Creator, Christians are convinced that the triumphs of the human race are a sign of God's grace and the flowering of His own mysterious design. For the greater man's power becomes, the farther his individual and community responsibility extends. Hence it is clear that men are not deterred by the Christian message from building up the world, or impelled to neglect the welfare of their fellows, but that they are rather more stringently bound to do these very things.[4]

35. Human activity, to be sure, takes its significance from its relationship to man. Just as it proceeds from man, so it is ordered toward man. For when a man works he not only alters things and society, he develops himself as well. He learns much, he cultivates his resources, he goes outside of himself and beyond himself. Rightly understood, this kind of growth is of greater value than any external riches which can be garnered. A man is more precious for what he is than for what he has.[5]

Similarly, all that men do to obtain greater justice, wider brotherhood, a more humane disposition of social relationships has greater worth than technical advances. For these advances can supply the material for human progress, but of themselves alone they can never actually bring it about.

Hence, the norm of human activity is this: that in accord with the divine plan and will, it harmonize with the genuine good of the human race, and that it allow men as individuals and as members of society to pursue their total vocation and fulfil it.

36. Now many of our contemporaries seem to fear that a closer bond between human activity and religion will work against the independence of men, of societies, or of the sciences.

If by the autonomy of earthly affairs we mean that created things and societies themselves enjoy their own laws and values which must be gradually deciphered, put to use, and regulated by men, then it is entirely right to demand that autonomy. Such is not merely required by modern man, but harmonizes also with the will of the Creator. For by the very circumstance of their having been created, all things are endowed with their own stability, truth, goodness, proper laws and order. Man must respect these as he isolates them by the appropriate methods of the individual sciences or arts. Therefore if methodical investigation within every branch of learning is carried out in a genuinely scientific manner and in accord with moral norms, it never truly conflicts with faith, for earthly matters and the concerns of faith derive from the same God.[6]

Indeed whoever labours to penetrate the secrets of reality with a humble and steady mind, even though he is unaware of the fact, is nevertheless being led by the hand of God, who holds all things in existence, and gives them their identity. Consequently, we cannot but deplore certain habits of mind, which are sometimes found too among Christians which do not sufficiently attend to the rightful independence of science and which, from the arguments and controversies they spark, lead many minds to conclude that faith and science are mutually opposed.[7]

But if the expression, the independence of temporal affairs, is taken to mean that created things do not depend on God, and that man can use them without any reference to their Creator, anyone who acknowledges God will see how false such a meaning is. For without the Creator the creature would disappear. For their part, however, all believers of whatever religion always hear His revealing voice in the discourse of creatures. When God is forgotten, however, the creature itself grows unintelligible.

37. Sacred Scripture teaches the human family what the experience of the ages confirms: that while human progress is a great advantage to man, it brings with it a strong temptation. For when the order of values is jumbled and bad is mixed with the good, individuals and groups pay heed solely to their own interests, and not to those of others. Thus it happens that the world ceases to be a place of true brotherhood. In our own day, the magnified power of humanity threatens to destroy the race itself.

For a monumental struggle against the powers of darkness pervades the whole history of man. The battle was joined from the very origins of the world and will continue until the last day, as the Lord has attested.[8]

Caught in this conflict, man is obliged to wrestle constantly if he is to cling to what is good, nor can he achieve his own integrity without great efforts and the help of God's grace.

That is why Christ's Church, trusting in the design of the Creator, acknowledges that human progress can serve man's true happiness, yet she cannot help echoing the Apostle's warning: "Be not conformed to this world" (Rom. 12:2). Here by the world is meant that spirit of vanity and malice which transforms into an instrument of sin those human energies intended for the service of God and man.

Hence if anyone wants to know how this unhappy situation can be overcome, Christians will tell him that all human activity, constantly imperiled by man's pride and deranged self-love, must be purified and perfected by the power of Christ's cross and resurrection. For redeemed by Christ and made a new creature in the Holy Spirit, man is able to love the things themselves created by God, and ought to do so. He can receive them from God and respect and reverence them as flowing constantly from the hand of God. Grateful to his Benefactor for these creatures, using and enjoying them in detachment and liberty of spirit, man is led forward into a true possession of them, as having nothing, yet possessing all things.[9] "All are yours, and you are Christ's, and Christ is God's" (1 Cor. 3:22-23).

38. For God's Word, through Whom all things were made, was Himself made flesh and dwelt on the earth of men.[10] Thus He entered the world's history as a perfect man, taking that history up into Himself and summarizing it.[11] He Himself revealed to us that "God is love" (1 John 4:8) and at the same time taught us that the new command of love was the basic law of human perfection and hence of the world's transformation.

To those, therefore, who believe in divine love, He gives assurance that the way of love lies open to men and that the effort to establish a universal brotherhood is not a hopeless one. He cautions them at the same time that this charity is not something to be reserved for important matters, but must be pursued chiefly in the ordinary circumstances of life. Undergoing death itself for all of us sinners, [12] He taught us by example that we too must shoulder that cross which the world and the flesh inflict upon those who search after peace and justice. Appointed Lord by His resurrection and given plenary power in heaven and on earth,[13] Christ is now at work in the hearts of men through the energy of His Holy Spirit, arousing not only a desire for the age to come, but by that very fact animating, purifying and strengthening those noble longings too by which the human family makes its life more human and strives to render the whole earth submissive to this goal.

Now, the gifts of the Spirit are diverse: while He calls some to give clear witness to the desire for a heavenly home and to keep that desire green among the human family, He summons others to dedicate themselves to the earthly service of men and to make ready the material of the celestial realm by this ministry of theirs. Yet He frees all of them so that by putting aside love of self and bringing all earthly resources into the service of human life they can devote themselves to that future when humanity itself will become an offering accepted by God.[14]

The Lord left behind a pledge of this hope and strength for life's journey in that sacrament of faith where natural elements refined by man are gloriously changed into His Body and Blood, providin mystical of brotherly solidarity and a foretaste of the heavenly banquet.

39. We do not know the time for the consummation of the earth and of humanity,[15] nor do we know how all things will be transformed. As deformed by sin, the shape of this world will pass away;[16] but we are taught that God is preparing a new dwelling place and a new earth where justice will abide,[17] and whose blessedness will answer and surpass all the longings for peace which spring up in the human heart.[18] Then, with death overcome, the sons of God will be raised up in Christ, and what was sown in weakness and corruption will be invested with incorruptibility.[19] Enduring with charity and its fruits,[20] all that creation[21] which God made on man's account will be unchained from the of vanity.

Therefore, while we are warned that it profits a man nothing if he gain the whole world and lose himself,[22] the expectation of a new earth must not weaken but rather stimulate our concern for cultivating this one. For here grows the body of a new human family, a body which even now is able to give some kind of foreshadowing of the new age.

Hence, while earthly progress must be carefully distinguished from the growth of Christ's kingdom, to the extent that the former can contribute to the better ordering of human society, it is of vital concern to the Kingdom of God.[23]

For after we have obeyed the Lord, and in His Spirit nurtured on earth the values of human dignity, brotherhood and freedom, and indeed all the good fruits of our nature and enterprise, we will find them again, but freed of stain, burnished and transfigured, when Christ hands over to the Father: "a kingdom eternal and universal, a kingdom of truth and life, of holiness and grace, of justice, love and peace."[24] On this earth that Kingdom is already present in mystery. When the Lord returns it will be brought into full flower.
