In this way he shares his beauty and happiness. He blesses everything and puts it in order. He lets the world and people grow and prosper. He is the guard of his creation. His Holy Spirit dwells among us a pledge of his presence. In the centre of the universe there is a human being. Accordingly, every man is the image of God. Every person is given the dignity of being the ruler of creation. For that reason, he is able to have dominion over the fish of the sea and the birds of the air. All creatures are supposed to serve the humans. The goal of all human generations is to find their Creator and to pay him homage.
