When _astronomy_ began to revolutionize man's idea of the solar universe, when for the first time in man's imagination the flat earth grew round and the stable earth began moving through space seventy-five times faster than a cannon-ball, Pope Paul V solemnly rendered a decree, that "the doctrine of the double motion of the earth about its axis and about the sun is false and entirely contrary to Holy Scripture." When _geology_ began to show from the rocks' unimpeachable testimony the long leisureliness of God, laying the foundations of the world, a Christian leader declared geology "not a subject of lawful inquiry," "a dark art," "dangerous and disreputable," "a forbidden province," "an awful evasion of the testimony of revelation." This tragic record of theology's vain conflict with science is the most pitiable part of the Church's story. How needless it was! For now when we face our universe of magnificent distances and regal laws has religion really suffered? Has a flat and stationary earth proved essential to Christianity, as Protestants and Catholics alike declared? Rather the Psalmist could not guess the sweep of our meaning when now we say, "The heavens declare the glory of God and the firmament showeth his handiwork" (Psalm 19:1). In the last generation the idea of _evolution_ was the occasion of a struggle like that which attended the introduction of the new astronomy. How was the world made? asked the ancient Hebrew, and he answered, By the word of God at a stroke. That was his scientific answer, and his religious answer too. When, therefore, the evolving universe was disclosed by modern science, when men read in fossil and in living biological structure the undeniable evidence of a long history of gradually changing forms of life, until the world was seen _not made like a box but growing like a tree_, many men of religion thought the faith destroyed. They identified the Christian Gospel with early Hebrew science! Today, however, when the general idea of evolution is taken for granted as gravitation is, how false this identification obviously appears! Says Professor Bowne, "An Eastern king was seated in a garden, and one of his counselors was speaking of the wonderful works of God. 'Show me a sign,' said the king, 'and I will believe.' 'Here are four acorns,' said the counselor; 'will your Majesty plant them in the ground, and then stoop down and look into this clear pool of water?' The king did so. 'Now,' said the other, 'Look up.' The king looked up and saw four oak trees where he had planted the acorns. 'Wonderful!' he exclaimed; 'this is indeed the work of God.' 'How long were you looking into the water?' asked the counselor. 'Only a second,' said the king. 'Eighty years have passed as a second,' said the other. The king looked at his garments; they were threadbare. He looked at his reflection in the water; he had become an old man. 'There is no miracle here, then,' he said angrily.
