... for the author of beauty created them

What can we learn of God in the study and contemplation of His Creation?

St. Paul's letter to the Romans 1:19-20:

For what can be known about God is plain to them, because God has shown it to them. Ever since the creation of the world his invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made. So they are without excuse;

Wisdom 13:1-9:

For all men who were ignorant of God were foolish by nature; and they were unable from the good things that are seen to know him who exists, nor did they recognize the craftsman while paying heed to his works; but they supposed that either fire or wind or swift air, or the circle of the stars, or turbulent water, or the luminaries of heaven were the gods that rule the world.

If through delight in the beauty of these things men assumed them to be gods, let them know how much better than these is their Lord, for the author of beauty created them. And if men were amazed at their power and working, let them perceive from them how much more powerful is he who formed them. For from the greatness and beauty of created things comes a corresponding perception of their Creator.

Yet these men are little to be blamed, for perhaps they go astray while seeking God and desiring to find him. For as they live among his works they keep searching, and they trust in what they see, because the things that are seen are beautiful. 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?
