Moses however makes a difference here, calling the sun and the moon the "greater lights." What philosophers say therefore concerning the magnitude of these bodies has properly nothing to do with the text before us. What we have here to do is to observe that the Scriptures do not speak of these bodies with reference to the magnitude of the bodies themselves but with reference to the magnitude of their light! For if you would compare the sun with the stars and collect all the stars into one body, you would have a body perhaps greater than the sun, but that whole body of stars together would not form a light equal to the light of the sun. On the contrary if you could divide the sun into minute particles, the most minute particles would surpass in brightness the brightest star. For all these bodies were created with an essential difference as Paul affirms. "There is one glory of the sun, and another glory of the moon, and another glory of the stars," etc., 1 Cor. 15:41. And this difference does not consist in the nature or magnitude of their bodies, but in the nature and essentiality of their creation itself; so that in this the work of God's creation is more wonderful. Hence marvellous beyond expression or thought is the fact that the rays of the sun should be dispersed through such length and breadth, with such wonderful properties of nourishment and heat to all bodies under their influence; and that, too, while the sun itself revolves with such amazing velocity. Astronomers say also that the stars are lighted as it were by the sun so that they shine. Likewise they say that the moon borrows its light from the sun. And this is beautifully proved in an eclipse of the moon, when the earth comes between the sun and moon and the light of the sun is not transmitted to the moon. I do not deny nor reject this, but I do hold however that it is of divine power that this efficacy is added to the sun to light and illumine even the distant moon and stars with its own light; and likewise that the moon and stars are so created that they have the capacity to receive the light that is projected from the sun so far away. Augustine sets forth two opinions about the moon in the beginning of the 12th Psalm, and in his discussions he forces an allegory upon the church, while he himself defines nothing. But I leave this; for from astronomers as from master artists we most readily learn what points are possible to be disputed in this science. I am satisfied that in these bodies so glorious and useful for our life we discern the goodness and power of God, who created such things by his Word and conserved them to the present day for our use. These are matters belonging to our calling or profession; that is, they are theological themes, and they have the efficacy to comfort and strengthen our hearts.
