planetary systems which are circling around some vast and distant sun. Science has taught us too that all this universe is linked together, bound together by a common law, bound together by a common order of phenomena. It has investigated the sun and the stars, it has analyzed their light, it has shown us that the substances of these bodies are identical with the substances of ours. It has taught us the unity of nature, it has taught us the vastness of nature. There are stars in the firmament which you can see with the naked eye, on which if a man were standing with a telescope fine enough and powerful enough to see what is transpiring on this globe, and should look through it to-day, he would see not this congregation assembled under this roof, but the first outbreaking of the revolution, so long does it take light to traverse from our globe to the stars, light that takes but eight minutes to travel from the sun to the earth. There are stars so distant that he would see not Chautauqua gathered here to-night, but the crucifixion of Christ taking place on the hill of Calvary; stars so distant, that with a telescope powerful enough to carry the message of this world to his sight, he would see Abraham coming out of the land of his idolatry into the promised land; stars so distant that he would see this earth first taking on its brightness in the birth-day of its glory. So vast is our universe that the mind can not attempt to comprehend its majestic distances. It is not theology, it is not religion, it is not even the Bible that has unfolded this vastness; it is science. It is impossible that men who have once learned anything of this greatness of creation, or anything of this unity of creation, should ever bow down again before idols of wood and stone. So long as men thought that the laws of the material universe were antagonistic and anarchic, that the universe was made up of warring tribes and provinces, so long it was not strange that they should worship many gods. So long as they thought that it was a little province on which they lived, the boundaries of which they could themselves measure with their tape-line, they might well worship before images they had formed with their utterances or with their hands. But to-day you might burn every Bible in the land, you might burn every church and Sunday-school house, you might put all the priests and ministers in America on the great bonfire, and consume them as well, and then you might erase from every mind every lesson that had been learned from church or Sunday-school, from priest or minister, and this nation could not go back to idolatry, unless it went back to the utter barbarism of utter ignorance. That which is highest and supremest in science you can learn without becoming a scientist; and you can not learn it without learning the large reverence that is the very foundation of religion.
