20. It now remains to inquire and show those who believe that the lights of heaven are set for signs, but have been misled by fanciful interpretations of the passages, why it is that God has made these signs in the sky. And we must first observe that if we believe the mind of God to be great enough to embrace the perfect knowledge of every individual existence, so that not the least ordinary occurrence escapes His Divinity, this belief involves the tenet, not demonstrably certain, but held as being consistent with the eternity of God's understanding, which transcends all nature, that His knowledge is, as it were, infinite. In order, then, that superhuman beings, and also the holy souls which have escaped from the bondage of this present state, may by experience grasp this truth, God created in the heavens beings who have been taught and shall be taught, as well by the revolution of the heavens as by other means, to read the signs which God gives as if they were written and stamped on the face of the sky. And it is not surprising that God should create some one for the sake of a manifestation to the blessed, for the Scripture saith to Pharaoh, "For this very purpose did I raise thee up, that I might show in thee my power, and that my name might be published abroad in all the |194 earth." For if Pharaoh was preserved for the sake of showing the power of God and publishing abroad His name in all the earth, consider what a marvellous manifestation of the power of God there is in the heavenly signs, for all of them have been from everlasting to everlasting engraved in the book of the heavens, a book worthy of God. And, secondly, I conjecture that the signs are exposed to the Powers which administer human affairs, in order that they may only know some things, and effect others; just as in our books some things are written that we may know them, as, for example, the story of the Creation, or any other mystery, and others that we may know and do them, as, for instance, the commandments and ordinances of God. It is indeed possible that the writings of the heavens, which Angels and Divine powers can read well, contain some things to be read by the Angels and ministers of God in order that they may rejoice in their knowledge; and other things in order that they may receive them as commandments and do them.
