Hear the Psalmist's claim:
The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge. They have no speech, they use no words; no sound is heard from them. Yet their voice goes out into all the earth, their words to the ends of the world. (Psm 19)
And Paul's assertion:
For since the creation of the world God's invisible qualities— his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. (Rom 1:20)
And St. Augustine's rebuke:
Some people, in order to discover God, read books. But there is a great book:the very appearance of created things. Look above you! Look below you! Read it. God, whom you want to discover, never wrote that book with ink. Instead He set before your eyes the things that He had made. Can you ask for a louder voice than that?
And St. Bernard of Clairvaux's (1090-1153) opinion:
Believe an expert: you will find something far greater in the woods than in books. Trees and stones will teach you that which you cannot learn from the masters.
