Augustine proceeds to comment on Genesis 1, i, and explains the "heaven" to mean that spiritual and incorporeal creation, which cleaves to God unintermittingly; "earth," the formless matter whereof the corporeal creation was afterwards formed. He does not reject, however, other interpretations, but rather confesses that manifold senses may and ought to be extracted from it.
It yet remains for a man to say, if he will, "that the already perfected and formed natures, visible and invisible, are not signified under the name of heaven and earth, when we read, In the beginning God made heaven and earth, but that the yet unformed commencement of things, the stuff apt to receive form and making, was called by these names, because therein were confusedly contained, not as yet distinguished by their qualities and forms, all those things which being now digested into order, are called Heaven and Earth, the one being the spiritual, the other the corporeal, creation."
All which things being heard and well considered, I will not strive about words: for that is profitable to nothing, but the subversion of the hearers. But the law is good to edify, if a man use it lawfully: for that the end of it is charity, out of a pure heart and good conscience, and faith unfeigned. And well did our Master know, upon which two commandments He hung all the Law and the Prophets. And what doth it prejudice me, O my God, Thou light of my eyes in secret, zealously confessing these things, since divers things may be understood under these words which yet are all true,--what, I say, doth it prejudice me, if I think otherwise than another thinketh the writer thought? All we readers verily strive to trace out and to understand his meaning whom we read; and seeing we believe him to speak truly, we dare not imagine him to have said any thing, which ourselves either know or think to be false. While every man endeavours then to understand in the holy Scriptures, the same as the writer understood, what hurt is it, if a man understand what Thou, the light of all true-speaking minds, dost show him to be true, although he whom he reads, understood not this, seeing he also understood a Truth, though not this truth?
For true it is, O Lord, that Thou madest heaven and earth; and it is true too, that the Beginning is Thy Wisdom, in Which Thou createdst all: and true again, that this visible world hath for its greater parts the heaven and the earth, which briefly comprise all made and created natures. And true too, that whatsoever is mutable, gives us to understand a certain want of form, whereby it receiveth a form, or is changed, or turned. It is true, that that is subject to no times, which so cleaveth to the unchangeable Form, as, though subject to change, never to be changed. It is true, that that formlessness which is almost nothing, cannot be subject to the alteration of times. It is true, that that whereof a thing is made, may by a certain mode of speech, be called by the name of the thing made of it; whence that formlessness, whereof heaven and earth were made, might be called heaven and earth. It is true, that of things having form, there is not any nearer to having no form, than the earth and the deep. It is true, that not only every created and formed thing, but whatsoever is capable of being created and formed, Thou madest, of whom are all things. It is true, that whatsoever is formed out of that which had no form, was unformed before it was formed.
Out of these truths, of which they doubt not whose inward eye Thou hast enabled to see such things, and who unshakenly believe Thy servant Moses to have spoken in the Spirit of truth;--of all these then, he taketh one, who saith, In the Beginning God made the heaven and the earth, that is, "in His word coeternal with Himself, God made the intelligible and the sensible, or the spiritual and the corporeal creature." He another, that saith, In the Beginning God made heaven and earth; that is, "in His Word coeternal with Himself, did God make the universal bulk of this corporeal world, together with all those apparent and known creatures, which it containeth." He another, that saith, In the Beginning God made heaven and earth: that is, "in His Word coeternal with Himself, did God make the formless matter of creatures spiritual and corporeal." He another, that saith, In the Beginning God created heaven and earth; that is, "in His Word coeternal with Himself, did God create the formless matter of the creature corporeal, wherein heaven and earth lay as yet confused, which, being now distinguished and formed, we at this day see in the bulk of this world." He another, who saith, In the Beginning God made heaven and earth, that is, "in the very beginning of creating and working, did God make that formless matter, confusedly containing in itself both heaven and earth; out of which, being formed, do they now stand out, and are apparent, with all that is in them."
And with regard to the understanding of the words following, out of all those truths, he chooses one to himself, who saith, But the earth was invisible, and without form, and darkness was upon the deep; that is, "that corporeal thing that God made, was as yet a formless matter of corporeal things, without order, without light." Another he who says, The earth was invisible and without form, and darkness was upon the deep; that is, "this all, which is called heaven and earth, was still a formless and darksome matter, of which the corporeal heaven and the corporeal earth were to be made, with all things in them, which are known to our corporeal senses." Another he who says, The earth was invisible and without form, and darkness was upon the deep; that is, "this all, which is called heaven and earth, was still a formless and a darksome matter; out of which was to be made, both that intelligible heaven, otherwhere called the Heaven of heavens, and the earth, that is, the whole corporeal nature, under which name is comprised this corporeal heaven also; in a word, out of which every visible and invisible creature was to be created." Another he who says, The earth was invisible and without form, and darkness was upon the deep, "the Scripture did not call that formlessness by the name of heaven and earth; but that formlessness, saith he, already was, which he called the earth invisible without form, and darkness upon the deep; of which he had before said, that God had made heaven and earth, namely, the spiritual and corporeal creature." Another he who says, The earth was invisible and without form, and darkness was upon the deep; that is, "there already was a certain formless matter, of which the Scripture said before, that God made heaven and earth; namely, the whole corporeal bulk of the world, divided into two great parts, upper and lower, with all the common and known creatures in them."
For should any attempt to dispute against these two last opinions, thus, "If you will not allow, that this formlessness of matter seems to be called by the name of heaven and earth; Ergo, there was something which God had not made, out of which to make heaven and earth; for neither hath Scripture told us, that God made this matter, unless we understand it to be signified by the name of heaven and earth, or of earth alone, when it is said, In the Beginning God made the heaven and earth; that so in what follows, and the earth was invisible and without form, (although it pleased Him so to call the formless matter), we are to understand no other matter, but that which God made, whereof is written above, God made heaven and earth." The maintainers of either of those two latter opinions will, upon hearing this, return for answer, "we do not deny this formless matter to be indeed created by God, that God of Whom are all things, very good; for as we affirm that to be a greater good, which is created and formed, so we confess that to be a lesser good which is made capable of creation and form, yet still good. We say however that Scripture hath not set down, that God made this formlessness, as also it hath not many others; as the Cherubim, and Seraphim, and those which the Apostle distinctly speaks of, Thrones, Dominions, Principalities, Powers. All which that God made, is most apparent. Or if in that which is said, He made heaven and earth, all things be comprehended, what shall we say of the waters, upon which the Spirit of God moved? For if they be comprised in this word earth; how then can formless matter be meant in that name of earth, when we see the waters so beautiful? Or if it be so taken; why then is it written, that out of the same formlessness, the firmament was made, and called heaven; and that the waters were made, is not written? For the waters remain not formless and invisible, seeing we behold them flowing in so comely a manner. But if they then received that beauty, when God said, Let the waters under the firmament be gathered together, that so the gathering together be itself the forming of them; what will be said as to those waters above the firmament? Seeing neither if formless would they have been worthy of so honourable a seat, nor is it written, by what word they were formed. If then Genesis is silent as to God's making of any thing, which yet that God did make neither sound faith nor well-grounded understanding doubteth, nor again will any sober teaching dare to affirm these waters to be coeternal with God, on the ground that we find them to be mentioned in the book of Genesis, but when they were created, we do not find; why (seeing truth teaches us) should we not understand that formless matter (which this Scripture calls the earth invisible and without form, and darksome deep) to have been created of God out of nothing, and therefore not to be coeternal to Him; notwithstanding this history hath omitted to show when it was created?"
