7. Of the nature of the first days, which are said to have had morning and evening, before there was a sun.
We see, indeed, that our ordinary days have no evening but by the setting, and no morning but by the rising, of the sun; but the first three days of all were passed without sun, since it is reported to have been made on the fourth day. And first of all, indeed, light was made by the word of God, and God, we read, separated it from the darkness, and called the light Day, and the darkness Night; but what kind of light that was, and by what periodic movement it made evening and morning, is beyond the reach of our senses; neither can we understand how it was, and yet must unhesitatingly believe it. For either it was some material light, whether proceeding from the upper parts of the world, far removed from our sight, or from the spot where the sun was afterwards kindled; or under the name of light the holy city was signified, composed of holy angels and blessed spirits, the city of which the apostle says, "Jerusalem which is above is our eternal mother in heaven;"[454] and in another place, "For ye are all the children of the light, and the children of the day; we are not of the night, nor of darkness."[455] Yet in some respects we may appropriately speak of a morning and evening of this day also. For the knowledge of the creature is, in comparison of the knowledge of the Creator, but a twilight; and so it dawns and breaks into morning when the creature is drawn to the praise and love of the Creator; and night never falls when the Creator is not forsaken through love of the creature. In fine, Scripture, when it would recount those days in order, never mentions the word night. It never says, "Night was," but "The evening and the morning were the first day." So of the second and the rest. And, indeed, the knowledge of created things contemplated by themselves is, so to speak, more colourless than when they are seen in the wisdom of God, as in the art by which they were made. Therefore evening is a more suitable figure than night; and yet, as I said, morning returns when the creature returns to the praise and love of the Creator. When it does so in the knowledge of itself, that is the first day; when in the knowledge of the firmament, which is the name given to the sky between the waters above and those beneath, that is the second day; when in the knowledge of the earth, and the sea, and all things that grow out of the earth, that is the third day; when in the knowledge of the greater and less luminaries, and all the stars, that is the fourth day; when in the knowledge of all animals that swim in the waters and that fly in the air, that is the fifth day; when in the knowledge of all animals that live on the earth, and of man himself, that is the sixth day.[456]
8. What we are to understand of God's resting on the seventh day, after the six days' work.
When it is said that God rested on the seventh day from all His works, and hallowed it, we are not to conceive of this in a childish fashion, as if work were a toil to God, who "spake and it was done,"—spake by the spiritual and eternal, not audible and transitory word. But God's rest signifies the rest of those who rest in God, as the joy of a house means the joy of those in the house who rejoice, though not the house, but something else, causes the joy. How much more intelligible is such phraseology, then, if the house itself, by its own beauty, makes the inhabitants joyful! For in this case we not only call it joyful by that figure of speech in which the thing containing is used for the thing contained (as when we say, "The theatres applaud," "The meadows low," meaning that the men in the one applaud, and the oxen in the other low), but also by that figure in which the cause is spoken of as if it were the effect, as when a letter is said to be joyful, because it makes its readers so. Most appropriately, therefore, the sacred narrative states that God rested, meaning thereby that those rest who are in Him, and whom He makes to rest. And this the prophetic narrative promises also to the men to whom it speaks, and for whom it was written, that they themselves, after those good works which God does in and by them, if they have managed by faith to get near to God in this life, shall enjoy in Him eternal rest. This was prefigured to the ancient people of God by the rest enjoined in their sabbath law, of which, in its own place, I shall speak more at large.
9. What the Scriptures teach us to believe concerning the creation of the angels.
At present, since I have undertaken to treat of the origin of the holy city, and first of the holy angels, who constitute a large part of this city, and indeed the more blessed part, since they have never been expatriated, I will give myself to the task of explaining, by God's help, and as far as seems suitable, the Scriptures which relate to this point. Where Scripture speaks of the world's creation, it is not plainly said whether or when the angels were created; but if mention of them is made, it is implicitly under the name of "heaven," when it is said, "In the beginning God created the heavens and the earth," or perhaps rather under the name of "light," of which presently. But that they were wholly omitted, I am unable to believe, because it is written that God on the seventh day rested from all His works which He made; and this very book itself begins, "In the beginning God created the heavens and the earth," so that before heaven and earth God seems to have made nothing. Since, therefore, He began with the heavens and the earth,—and the earth itself, as Scripture adds, was at first invisible and formless, light not being as yet made, and darkness covering the face of the deep (that is to say, covering an undefined chaos of earth and sea, for where light is not, darkness must needs be),—and then when all things, which are recorded to have been completed in six days, were created and arranged, how should the angels be omitted, as if they were not among the works of God, from which on the seventh day He rested? Yet, though the fact that the angels are the work of God is not omitted here, it is indeed not explicitly mentioned; but elsewhere Holy Scripture asserts it in the clearest manner. For in the Hymn of the Three Children in the Furnace it was said, "O all ye works of the Lord, bless ye the Lord;"[457] and among these works mentioned afterwards in detail, the angels are named. And in the psalm it is said, "Praise ye the Lord from the heavens, praise Him in the heights. Praise ye Him, all His angels; praise ye Him, all His hosts. Praise ye Him, sun and moon; praise Him, all ye stars of light. Praise Him, ye heaven of heavens; and ye waters that be above the heavens. Let them praise the name of the Lord; for He commanded, and they were created."[458] Here the angels are most expressly and by divine authority said to have been made by God, for of them among the other heavenly things it is said, "He commanded, and they were created." Who, then, will be bold enough to suggest that the angels were made after the six days' creation? If any one is so foolish, his folly is disposed of by a scripture of like authority, where God says, "When the stars were made, the angels praised me with a loud voice."[459] The angels therefore existed before the stars; and the stars were made the fourth day. Shall we then say that they were made the third day? Far from it; for we know what was made that day. The earth was separated from the water, and each element took its own distinct form, and the earth produced all that grows on it. On the second day, then? Not even on this; for on it the firmament was made between the waters above and beneath, and was called "Heaven," in which firmament the stars were made on the fourth day. There is no question, then, that if the angels are included in the works of God during these six days, they are that light which was called "Day," and whose unity Scripture signalizes by calling that day not the "first day," but "one day."[460] For the second day, the third, and the rest are not other days; but the same "one" day is repeated to complete the number six or seven, so that there should be knowledge both of God's works and of His rest. For when God said, "Let there be light, and there was light," if we are justified in understanding in this light the creation of the angels, then certainly they were created partakers of the eternal light which is the unchangeable Wisdom of God, by which all things were made, and whom we call the only-begotten Son of God; so that they, being illumined by the Light that created them, might themselves become light and be called "Day," in participation of that unchangeable Light and Day which is the Word of God, by whom both themselves and all else were made. "The true Light, which lighteth every man that cometh into the world,"[461]—this Light lighteth also every pure angel, that he may be light not in himself, but in God; from whom if an angel turn away, he becomes impure, as are all those who are called unclean spirits, and are no longer light in the Lord, but darkness in themselves, being deprived of the participation of Light eternal. For evil has no positive nature; but the loss of good has received the name "evil."[462]
10. Of the simple and unchangeable Trinity, Father, Son, and Holy Ghost, one God, in whom substance and quality are identical.
There is, accordingly, a good which is alone simple, and therefore alone unchangeable, and this is God. By this Good have all others been created, but not simple, and therefore not unchangeable. "Created," I say,—that is, made, not begotten. For that which is begotten of the simple Good is simple as itself, and the same as itself. These two we call the Father and the Son; and both together with the Holy Spirit are one God; and to this Spirit the epithet Holy is in Scripture, as it were, appropriated. And He is another than the Father and the Son, for He is neither the Father nor the Son. I say "another," not "another thing," because He is equally with them the simple Good, unchangeable and co-eternal. And this Trinity is one God; and none the less simple because a Trinity. For we do not say that the nature of the good is simple, because the Father alone possesses it, or the Son alone, or the Holy Ghost alone; nor do we say, with the Sabellian heretics, that it is only nominally a Trinity, and has no real distinction of persons; but we say it is simple, because it is what it has, with the exception of the relation of the persons to one another. For, in regard to this relation, it is true that the Father has a Son, and yet is not Himself the Son; and the Son has a Father, and is not Himself the Father. But, as regards Himself, irrespective of relation to the other, each is what He has; thus, He is in Himself living, for He has life, and is Himself the Life which He has.
It is for this reason, then, that the nature of the Trinity is called simple, because it has not anything which it can lose, and because it is not one thing and its contents another, as a cup and the liquor, or a body and its colour, or the air and the light or heat of it, or a mind and its wisdom. For none of these is what it has: the cup is not liquor, nor the body colour, nor the air light and heat, nor the mind wisdom. And hence they can be deprived of what they have, and can be turned or changed into other qualities and states, so that the cup may be emptied of the liquid of which it is full, the body be discoloured, the air darken, the mind grow silly. The incorruptible body which is promised to the saints in the resurrection cannot, indeed, lose its quality of incorruption, but the bodily substance and the quality of incorruption are not the same thing. For the quality of incorruption resides entire in each several part, not greater in one and less in another; for no part is more incorruptible than another. The body, indeed, is itself greater in whole than in part; and one part of it is larger, another smaller, yet is not the larger more incorruptible than the smaller. The body, then, which is not in each of its parts a whole body, is one thing; incorruptibility, which is throughout complete, is another thing;—for every part of the incorruptible body, however unequal to the rest otherwise, is equally incorrupt. For the hand, e.g., is not more incorrupt than the finger because it is larger than the finger; so, though finger and hand are unequal, their incorruptibility is equal. Thus, although incorruptibility is inseparable from an incorruptible body, yet the substance of the body is one thing, the quality of incorruption another. And therefore the body is not what it has. The soul itself, too, though it be always wise (as it will be eternally when it is redeemed), will be so by participating in the unchangeable wisdom, which it is not; for though the air be never robbed of the light that is shed abroad in it, it is not on that account the same thing as the light. I do not mean that the soul is air, as has been supposed by some who could not conceive a spiritual nature;[463] but, with much dissimilarity, the two things have a kind of likeness, which makes it suitable to say that the immaterial soul is illumined with the immaterial light of the simple wisdom of God, as the material air is irradiated with material light, and that, as the air, when deprived of this light, grows dark, (for material darkness is nothing else than air wanting light,[464]) so the soul, deprived of the light of wisdom, grows dark.
According to this, then, those things which are essentially and truly divine are called simple, because in them quality and substance are identical, and because they are divine, or wise, or blessed in themselves, and without extraneous supplement. In Holy Scripture, it is true, the Spirit of wisdom is called "manifold"[465] because it contains many things in it; but what it contains it also is, and it being one is all these things. For neither are there many wisdoms, but one, in which are untold and infinite treasures of things intellectual, wherein are all invisible and unchangeable reasons of things visible and changeable which were created by it.[466] For God made nothing unwittingly; not even a human workman can be said to do so. But if He knew all that He made, He made only those things which He had known. Whence flows a very striking but true conclusion, that this world could not be known to us unless it existed, but could not have existed unless it had been known to God.
