Thus also that the motion of the planets retrogrades is the work of God created by his Word, which work belongs to God himself, which is greater and higher than can be attributed to angels, but God, who thus distinguished these things, governs and preserves them. And it is the same God who commanded the sun to start in its course but the firmament to stand still, said also to the planets and the stars, thou shaft move so and so. The Word does even this; namely, it makes the most uncertain motion the most certain, even though these heavenly material bodies move in the fluctuating atmosphere, and not in any place or along any material line. For as a fish in the middle of the sea, a bird in the open heavens, so the stars move in their appointed course, but in a motion most secure and very wonderful indeed. Thus also this is clearly the cause why the Elbe river here at Wittenberg and in this district has its fixed and continuous course and dare not become weary. All such works are the works of the Word, which Moses here honors and praises: "He said," etc. But we Christians ought to meditate and think on these things and their causes differently from philosophers. Although there are some things which are beyond our comprehension, as for instance these waters that are "above" the firmament, all such things are rather to be believed with a confession of our ignorance than profanely denied, or arrogantly interpreted according to our shallow comprehension. It behooves us ever to adhere to the phraseology of the holy Scriptures, and to stand by the very words of the Holy Spirit, whom it pleased in this sacred narrative by his servant Moses, so to arrange the different parts of the great work of creation, as to place in the midst "the firmament;" formed out of the original mass of the unshapen heaven and earth, and stretched out and expanded by the Word; and then to represent some waters as being "above" that firmament and other waters "under" that firmament, both waters being also formed out of the same original rude undigested matter. And the whole of this part of the creation is called by the Holy Spirit the heaven; together also with its seven spheres and the whole region of the air; in which are meteors and signs of fire and in which the wandering fowls make their homes. Therefore these common principles we will not oppose nor deny, when they say everything by nature sinks under itself, and everything light rises above itself, although we also see that dense heavy vapors arise but by reason of the influence and motion of heat. We say also that all these things were thus created and maintained by the Word, and they can also by virtue of the power in the same Word be changed yet today; as all nature will finally be altogether transformed. Thus also it is contrary to the rule given that waters should be above the heaven or firmament, and yet the text affirms it.
