Is it not true that what we call “nature” in a cosmic sense has its origin in “a plan of love and truth”? The world “is not the product of any necessity whatsoever, nor of blind fate or chance… The world proceeds from the free will of God; he wanted to make his creatures share in his being, in his intelligence, and in his goodness.”[ix] The Book of Genesis, in its very first pages, points to the wise design of the cosmos: it comes forth from God’s mind and finds its culmination in man and woman, made in the image and likeness of the Creator to “fill the earth” and to “have dominion over” it as “stewards” of God himself (cf. Gen 1:28). The harmony between the Creator, mankind and the created world, as described by Sacred Scripture, was disrupted by the sin of Adam and Eve, by man and woman, who wanted to take the place of God and refused to acknowledge that they were his creatures. As a result, the work of “exercising dominion” over the earth, “tilling it and keeping it,” was also disrupted, and conflict arose within and between mankind and the rest of creation (cf. Gen 3:17‒19). Human beings let themselves be mastered by selfishness; they misunderstood the meaning of God’s command and exploited creation out of a desire to exercise absolute domination over it. But the true meaning of God’s original command, as the Book of Genesis clearly shows, was not a simple conferral of authority, but rather a summons to responsibility. The wisdom of the ancients had recognized that nature is not at our disposal as “a heap of scattered refuse.”[x] Biblical Revelation made us see that nature is a gift of the Creator, who gave it an inbuilt order and enabled man to draw from it the principles needed to “till it and keep it” (cf. Gen. 2:15).[xi] Everything that exists belongs to God, who has entrusted it to man, albeit not for his arbitrary use. Once man, instead of acting as God’s co-worker, sets himself up in place of God, he ends up provoking a rebellion on the part of nature, “which is more tyrannized than governed by him.”[xii] Man thus has a duty to exercise responsible stewardship over creation, to care for it and to cultivate it.[xiii]
