These things have their place and use as rudiments or primary principles, which if any one contend that they are not universally true, yet they are true in general and serve to the end that we may learn and hand down to others the true theories. For though fire can be struck from flint, yet it cannot therefore be denied that in the highest regions there is fire. Therefore theology gives these theorists this rule, which philosophy does not know sufficiently, that although God ordained and created all these things by his Word, yet he is not therefore bound to these rules so that he can not change them according to his good pleasure. For we see that neither grammar nor the other sciences are so perfectly set forth in rules that there are no exceptions; thus the laws of public and secular affairs step in and temper all things with reason. How much more can this be done in divine things, so that, although we indeed experience that the four elements are ordained and disposed by God, yet they can, contrary to this order, also have and maintain fire in the middle of the ocean, just as we saw that it was hidden in flint.

Likewise the mathematicians have concluded that there were a definite number of spheres, not that it is necessary to be so, but because one can not teach anything definitely about such things unless one distinguishes the spheres thus, on account of the variety of their motions, about which one can teach nothing without such imagination, if I may so name it. For teachers and professors of these sciences or theories say: We give examples, not because they are in every detail correct, but in order that no one may teach differently concerning those subjects. Therefore it would be the height of folly to despise and ridicule such things as some do, because it is not so sure that it could not be different, for they serve to the end that good arts and sciences may be taught, and that is sufficient.

The philosophers in general teach such things, to which the more modern theologians agree and add to these eight spheres two more,—the crystalline, glacial or aqueous heaven, and then the empyreal or fiery heaven. The Greeks however have discussed these themes much more elegantly and prudently than our scholars. For Ambrose and Augustine have had very childish thoughts. Therefore I praise Jerome because he simply passed over them in silence.

There are some who hold that the crystalline heaven is watery, because they think it is the waters of which Moses here speaks, and there the firmament or eighth sphere is added so that they be not consumed by their rapid and constant motion. But these are puerile thoughts, and I will rather confess that I do not understand Moses in this passage than that I should approve such illiterate thoughts.

The seventh heaven they call empyreal; not because it is fiery or burning, but from the light which is lucid and splendid. This heaven in the home of God and of the blessed, because it was filled immediately after creation with angels, and Lucifer, as they affirm, fell from this heaven. These are about all the ideas that theologians have added to the opinions of philosophers.

However, our scientists, who have studied astronomy, teach that there are still more spheres; namely, twelve, and three motions in the eight spheres; as, the motum raptum, motum proprium, motum trepidationis, a rending motion, a characteristic motion, and a trembling motion. For of such things indeed one cannot speak, unless he give each motion its own sphere.

Averrois had other thoughts, more absurd and far more in agreeable to reason. For he advocated that each sphere was an intellect, or an intelligent nature. The occasion or cause of these foolish thoughts was that he saw the infallibly perfect and most regular motion of the heavenly bodies. Therefore he thought these spheres were intelligent substances, each setting itself in motion in a sure and continuous manner. But from this follows the greatest and worst ignorance of God; wherefore we repudiate the thoughts of Averrois. But the others, which we have mentioned, we approve in so far as they are useful to be taught. For indeed this knowledge of the motion of the heavenly bodies is most worthy of all praise, however little that knowledge may be.

Moses however proceeds with his narrative of the creation in all simplicity and plainness, as they say; making here three divisions: waters "above" the firmament, waters "under" the firmament, and "the firmament" in the middle. In the term heaven, Moses comprehends all that body which philosophers represent by their eight spheres, by fire and by air. For the sacred historian makes no mention of the flowing of the waters until the third day. And it is manifest that the air in which we live is called in the holy Scriptures the heaven; because the Scriptures speak of the "fowls of heaven," Job 28:21; Ps. 8:8. It also speaks of the heavens being shut when it does not rain, 1 Kings 8:35. And again it speaks of the heavens giving their dew, Zech. 8:12; all these things take place in the air, not in the spheres of the moon or of the other planets. This distinction of the spheres therefore is not Mosaic nor scriptural but is an invention of men as an aid to instruction on these astronomical subjects; and which ought not to be despised as such an assistance.

And although they say that the elements are corruptible, yet I doubt it, for I see indeed that they remain. And although a part at times is changed, yet it follows that the whole will be changed; but these changes of the elements are only in part. Thus the air remains unchanged in which the birds live and fly; also the earth upon which the trees and other things grow, though certain parts of the same are changed.

Now Aristotle makes the cause of all these things the first mover, primum motorem. Averrois however says the cause of these motions are "formae assistentes a foris;" that is, intelligent natures which move from without. Following Moses we say that all these things are brought forth and governed simply by the Word of God. He spake and it was done. He never commanded that the angels should govern these bodies; just as we ourselves are not governed by the angels, although we are guarded and kept by the angels.

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.

To return therefore unto the principal matter before us; when any inquiry is instituted as to the nature of these waters, it cannot be denied that Moses here affirms that waters are "above" the heaven; but of what kind or nature these waters are, I freely confess for myself that I know not; for the Scriptures make no other mention of them than in this verse, and in the Song of the three children, in the Apocrypha, Dan. 3:61; and I can attempt to declare nothing certain on these and similar subjects. Hence I can say nothing whatever as known and understood concerning the heaven where the angels are and where God dwells with the blessed; nor concerning other kindred things, which shall be revealed unto us in the last day, when we shall have been clothed with another body.

But I add, for the sake of those who do not understand this, that in the Scriptures the word heaven often signifies what we call the horizon. Hence the whole firmament is called the heaven of heavens, in which are gathered the heaven of all human beings; that is, the horizon. In this respect we have a different heaven here in Germany than the people in France or Italy. But this name helps nothing at all in the explanation of our text. Therefore the greater number of theologians interpret here waters, as also indicated above, the glacial heaven, the cold heaven, which is located where it is that it may moisten and refresh the lower sphere in their great and swift motion, lest they be consumed by their excessive heat. But whether they have thus concluded correctly, I will leave unanswered.

I freely confess that I do not know what kind of waters these are. For the old teachers of the church did not specially worry about this, as we see Augustine condemned all astrology. Although it contains much superstition, yet it should not be entirely despised, for it is wholly given up to the observation and consideration of divine themes, a zeal and diligence most worthy of human beings. Therefore we find that many most highly talented and excellent persons have exercised themselves in astrology and obtained pleasure from it.

Sufficient has been said on this subject to show that on the second day the heaven was separated and located so that it stood in the middle between the waters.

III. But here another question presents itself. To the works of all the other days there is added the divine sentence of approbation, "And God saw that it was good." How is it then that the same sentence is not added to the second day's work, when the greatest and most beautiful part of the whole creation was made? To this question it may be replied, that this same divine sentence is added at the end of the creation of all things on the sixth day and more fully expressed thus, "And God saw everything that he had made, and, behold, it was very good." And these words apply to the heaven also.

Lyra is inclined to think with Rabbi Solomon, that as this divine expression, "And God saw that it was good," is uttered twice during the third day's work, one of the divine sentences refers to the second day's work; which was perfected on the third day, when the waters which are "under" the heaven were more distinctly divided from the waters which were "above" the heaven. But it is by far the safest way not to be too curious and inquiring on these subjects; because they exceed our human capacity.

Others speculate here and give reasons they understand not, that the second number is of an evil omen, because it is the first number that departs from the unity of God, but God was displeased with this digression and approved of the unity, and therefore he did not add the clause "it was good" on the second day. Lyra is however right in calling this a misleading and dangerous explanation. For in this manner all the numbers depart from the Unity.

Therefore it is far the safest not to be too curious and inquiring in these subjects, because they are placed above our human capacity. For how can we understand that order which God himself establishes and approves. Yes, reason must here be put to shame, for what is order in the eyes of God we judge to be the confusion of order. Thus the stars seem to us to be arranged thoughtlessly in wild disorder in that the bright ones are scattered among those more obscure, and the lesser among the greater. Who would judge this to be order? And yet it is the most perfect harmony, so constituted by the all-wise mind itself. In like manner we judge of other matters. It seems confusing that our Elbe and all rivers flow to the sea in an irregular winding course. Such disorder there seems to be also among trees, yes, between man and wife, where it appears there is no order. But all this only proves that God is a God of order and that his judgment as to order is quite different than ours.

We therefore cease to follow more curiously the question why God added twice to the third day, "And God saw," etc., and omitted it on the second day. Nor will we conclude rashly whether the work of the second day was finished in the third day or not. Philosophers have handed down the rudiments of the arts and of the science of astronomy, and in doing so they divided the heaven into various spheres. We have a much simpler theory or science, in that we at once make God the immediate Creator of all things by his Word, Dixit, "And God said."

For how can we understand that order which God approves as such? Nay, our natural reason must here of necessity be confounded; for that which is order with God is in our judgment confusion. Hence the stars appear to us to be in a state of wild disorder; the bright being mingled with the more obscure, and the lesser with the greater. Who would judge this to be order? And yet it is consummate harmony; and so constituted by the all-wise Mind. And so we judge of other things. Our river Elbe seems a confusion; as do all other rivers also; because their streams empty themselves into the sea by winding courses. In the same manner trees seem to present a confusion. Nor do males and females in the world and their unions and combinations appear to be a state of order. All here also as to the appearance of things is disorder and confusion. All these things therefore unitedly prove that God possesses an order, and judges of it, differently from ourselves.

Cease we therefore to penetrate into these things with too much curiosity, why it is that God repeats the divine sentence in question twice during the work of the third day and omits it altogether in the work of the second day? Nor determine we rashly whether the work of the second day was finished on the third day or not. Philosophers laid down the rudiments of the arts and of the science of astronomy; and in so doing they divided the heaven into its various spheres. But we adopt a simpler and more true method of procedure and judgment; for we at once make God the immediate Creator of all things by his Word, "And God said."
