85. What task does man have in the visible creation?

God has assigned human beings their living environment and given them the commission to have “dominion” over the earth—that is, to shape it—and to protect it (cf. Genesis 1: 26, 28; Psalm 8: 6).

“Then God blessed them, and God said to them, ‘Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth’.”
Genesis 1: 28
