CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 342–346

342 The hierarchy of creatures is expressed by the order of the "six days", from the less perfect to the more perfect. God loves all his creatures and takes care of each one, even the sparrow. Nevertheless, Jesus said: "You are of more value than many sparrows", or again: "Of how much more value is a man than a sheep!"
343 Man is the summit of the Creator's work, as the inspired account expresses by clearly distinguishing the creation of man from that of the other creatures.
344 There is a solidarity among all creatures arising from the fact that all have the same Creator and are all ordered to his glory: May you be praised, O Lord, in all your creatures, especially brother sun, by whom you give us light for the day; he is beautiful, radiating great splendor, and offering us a symbol of you, the Most High. . .

May you be praised, my Lord, for sister water, who is very useful and humble, precious and chaste. . .
May you be praised, my Lord, for sister earth, our mother, who bears and feeds us, and produces the variety of fruits and dappled flowers and grasses. . .
Praise and bless my Lord, give thanks and serve him in all humility.

345 The sabbath - the end of the work of the six days. The sacred text says that "on the seventh day God finished his work which he had done", that the "heavens and the earth were finished", and that God "rested" on this day and sanctified and blessed it. These inspired words are rich in profitable instruction:
346 In creation God laid a foundation and established laws that remain firm, on which the believer can rely with confidence, for they are the sign and pledge of the unshakeable faithfulness of God's covenant. For his part man must remain faithful to this foundation, and respect the laws which the Creator has written into it.
