"For from the greatness and beauty of created things comes a corresponding perception of their Creator." (Wisdom 13:5)
Wisdom reflects on the origin of idolatry: all people who were ignorant of God were foolish by nature; and they were unable from the good things that are seen to know the one who exists, nor did they recognise the craftsman while paying heed to his works. If through delight in the beauty of these things people assumed them to be gods, let them know how much better than these is their Lord, for from the greatness and beauty of created things comes a corresponding perception of their Creator. Yet again, not even they are to be excused; for if they had the power to know so much that they could investigate the world, how did they fail to find sooner the Lord of these things? Those who mistake natural phenomena for gods are still less excusable than those who construct idols with their own hands.
The Catechism identifies this passage as the foundational text for natural theology: the created world is sufficient to lead the human mind to a perception of the Creator, and the failure to make this journey is therefore without full excuse (CCC 1147).
Brothers and sisters, from the greatness and beauty of created things comes a corresponding perception of their Creator. Every time you are struck by the beauty of the physical world, you are receiving an invitation. The beauty is not the Creator but the Creator's signature. Follow the signature to the one who left it.
Lord God, from the greatness and beauty of your creation we perceive you. Keep our eyes open to the invitation in every beautiful thing. Through Christ our Lord. Amen.
