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.
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 splendour, 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.
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:
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.
Creation was fashioned with a view to the sabbath and therefore for the worship and adoration of God. Worship is inscribed in the order of creation. As the rule of St. Benedict says, nothing should take precedence over “the work of God”, that is, solemn worship. This indicates the right order of human concerns.
The sabbath is at the heart of Israel’s law. To keep the commandments is to correspond to the wisdom and the will of God as expressed in his work of creation.
The eighth day. But for us a new day has dawned: the day of Christ’s Resurrection. the seventh day completes the first creation. the eighth day begins the new creation. Thus, the work of creation culminates in the greater work of redemption. the first creation finds its meaning and its summit in the new creation in Christ, the splendour of which surpasses that of the first creation.
