Summa Th. I EN Qu.70 a.3


Question: 71 ON THE WORK OF THE FIFTH DAY (ONE ARTICLE)





We must next consider the work of the fifth day.

Objection: 1. It would seem that this work is not fittingly described. For the waters produce that which the power of water suffices to produce. But the power of water does not suffice for the production of every kind of fishes and birds since we find that many of them are generated from seed. Therefore the words, "Let the waters bring forth the creeping creature having life, and the fowl that may fly over the earth," do not fittingly describe this work.

2. Further, fishes and birds are not produced from water only, but earth seems to predominate over water in their composition, as is shown by the fact that their bodies tend naturally to the earth and rest upon it. It is not, then, fittingly that fishes and birds are produced from water.

3. Further, fishes move in the waters, and birds in the air. If, then, fishes are produced from the waters, birds ought to be produced from the air, and not from the waters.

4. Further, not all fishes creep through the waters, for some, as seals, have feet and walk on land. Therefore the production of fishes is not sufficiently described by the words, "Let the waters bring forth the creeping creature having life."

5. Further, land animals are more perfect than birds and fishes which appears from the fact that they have more distinct limbs, and generation of a higher order. For they bring forth living beings, whereas birds and fishes bring forth eggs. But the more perfect has precedence in the order of nature. Therefore fishes and birds ought not to have been produced on the fifth day, before land animals.

On the contrary Suffices the authority of Scripture.

I answer that As said above, (Question [70], Article [1]), the order of the work of adornment corresponds to the order of the work of distinction. Hence, as among the three days assigned to the work of distinction, the middle, or second, day is devoted to the work of distinction of water, which is the intermediate body, so in the three days of the work of adornment, the middle day, which is the fifth, is assigned to the adornment of the intermediate body, by the production of birds and fishes. As, then, Moses makes mention of the lights and the light on the fourth day, to show that the fourth day corresponds to the first day on which he had said that the light was made, so on this fifth day he mentions the waters and the firmament of heaven to show that the fifth day corresponds to the second. It must, however, be observed that Augustine differs from other writers in his opinion about the production of fishes and birds, as he differs about the production of plants. For while others say that fishes and birds were produced on the fifth day actually, he holds that the nature of the waters produced them on that day potentially.

Reply to Objection: 1. It was laid down by Avicenna that animals of all kinds can be generated by various minglings of the elements, and naturally, without any kind of seed. This, however, seems repugnant to the fact that nature produces its effects by determinate means, and consequently, those things that are naturally generated from seed cannot be generated naturally in any other way. It ought, then, rather to be said that in the natural generation of all animals that are generated from seed, the active principle lies in the formative power of the seed, but that in the case of animals generated from putrefaction, the formative power of is the influence of the heavenly bodies. The material principle, however, in the generation of either kind of animals, is either some element, or something compounded of the elements. But at the first beginning of the world the active principle was the Word of God, which produced animals from material elements, either in act, as some holy writers say, or virtually, as Augustine teaches. Not as though the power possessed by water or earth of producing all animals resides in the earth and the water themselves, as Avicenna held, but in the power originally given to the elements of producing them from elemental matter by the power of seed or the influence of the stars.

2. The bodies of birds and fishes may be considered from two points of view. If considered in themselves, it will be evident that the earthly element must predominate, since the element that is least active, namely, the earth, must be the most abundant in quantity in order that the mingling may be duly tempered in the body of the animal. But if considered as by nature constituted to move with certain specific motions, thus they have some special affinity with the bodies in which they move; and hence the words in which their generation is described.

3. The air, as not being so apparent to the senses, is not enumerated by itself, but with other things: partly with the water, because the lower region of the air is thickened by watery exhalations; partly with the heaven as to the higher region. But birds move in the lower part of the air, and so are said to fly "beneath the firmament," even if the firmament be taken to mean the region of clouds. Hence the production of birds is ascribed to the water.

4. Nature passes from one extreme to another through the medium; and therefore there are creatures of intermediate type between the animals of the air and those of the water, having something in common with both; and they are reckoned as belonging to that class to which they are most allied, through the characters possessed in common with that class, rather than with the other. But in order to include among fishes all such intermediate forms as have special characters like to theirs, the words, "Let the waters bring forth the creeping creature having life," are followed by these: "God created great whales," etc.

5. The order in which the production of these animals is given has reference to the order of those bodies which they are set to adorn, rather than to the superiority of the animals themselves. Moreover, in generation also the more perfect is reached through the less perfect.



Question: 72 ON THE WORK OF THE SIXTH DAY (ONE ARTICLE)





We must now consider the work of the sixth day.

Objection: 1. It would seem that this work is not fittingly described. For as birds and fishes have a living soul, so also have land animals. But these animals are not themselves living souls. Therefore the words, "Let the earth bring forth the living creature," should rather have been, "Let the earth bring forth the living four-footed creatures."

2. Further, a genus ought not to be opposed to its species. But beasts and cattle are quadrupeds. Therefore quadrupeds ought not to be enumerated as a class with beasts and cattle.

3. Further, as animals belong to a determinate genus and species, so also does man. But in the making of man nothing is said of his genus and species, and therefore nothing ought to have been said about them in the production of other animals, whereas it is said "according to its genus" and "in its species."

4. Further, land animals are more like man, whom God is recorded to have blessed, than are birds and fishes. But as birds and fishes are said to be blessed, this should have been said, with much more reason, of the other animals as well.

5. Further, certain animals are generated from putrefaction, which is a kind of corruption. But corruption is repugnant to the first founding of the world. Therefore such animals should not have been produced at that time.

6. Further, certain animals are poisonous, and injurious to man. But there ought to have been nothing injurious to man before man sinned. Therefore such animals ought not to have been made by God at all, since He is the Author of good; or at least not until man had sinned.

On the contrary Suffices the authority of Scripture.

I answer that As on the fifth day the intermediate body, namely, the water, is adorned, and thus that day corresponds to the second day; so the sixth day, on which the lowest body, or the earth, is adorned by the production of land animals, corresponds to the third day. Hence the earth is mentioned in both places. And here again Augustine says (Gn ad lit. v) that the production was potential, and other holy writers that it was actual.

Reply to Objection: 1. The different grades of life which are found in different living creatures can be discovered from the various ways in which Scripture speaks of them, as Basil says (Hom. viii in Hexaem.). The life of plants, for instance, is very imperfect and difficult to discern, and hence, in speaking of their production, nothing is said of their life, but only their generation is mentioned, since only in generation is a vital act observed in them. For the powers of nutrition and growth are subordinate to the generative life, as will be shown later on (Question [78], Article [2]). But amongst animals, those that live on land are, generally speaking, more perfect than birds and fishes, not because the fish is devoid of memory, as Basil upholds (Hom. viii in Hexaem.) and Augustine rejects (Gn ad lit. iii), but because their limbs are more distinct and their generation of a higher order, (yet some imperfect animals, such as bees and ants, are more intelligent in certain ways). Scripture, therefore, does not call fishes "living creatures," but "creeping creatures having life"; whereas it does call land animals "living creatures" on account of their more perfect life, and seems to imply that fishes are merely bodies having in them something of a soul, whilst land animals, from the higher perfection of their life, are, as it were, living souls with bodies subject to them. But the life of man, as being the most perfect grade, is not said to be produced, like the life of other animals, by earth or water, but immediately by God.

2. By "cattle," domestic animals are signified, which in any way are of service to man: but by "beasts," wild animals such as bears and lions are designated. By "creeping things" those animals are meant which either have no feet and cannot rise from the earth, as serpents, or those whose feet are too short to life them far from the ground, as the lizard and tortoise. But since certain animals, as deer and goats, seem to fall under none of these classes, the word "quadrupeds" is added. Or perhaps the word "quadruped" is used first as being the genus, to which the others are added as species, for even some reptiles, such as lizards and tortoises, are four-footed.

3. In other animals, and in plants, mention is made of genus and species, to denote the generation of like from like. But it was unnecessary to do so in the case of man, as what had already been said of other creatures might be understood of him. Again, animals and plants may be said to be produced according to their kinds, to signify their remoteness from the Divine image and likeness, whereas man is said to be made "to the image and likeness of God."

4. The blessing of God gives power to multiply by generation, and, having been mentioned in the preceding account of the making of birds and fishes, could be understood of the beasts of the earth, without requiring to be repeated. The blessing, however, is repeated in the case of man, since in him generation of children has a special relation to the number of the elect [*Cf. Augustine, Gen. ad lit. iii, 12], and to prevent anyone from saying that there was any sin whatever in the act of begetting children. As to plants, since they experience neither desire of propagation, nor sensation in generating, they are deemed unworthy of a formal blessing.

5. Since the generation of one thing is the corruption of another, it was not incompatible with the first formation of things, that from the corruption of the less perfect the more perfect should be generated. Hence animals generated from the corruption of inanimate things, or of plants, may have been generated then. But those generated from corruption of animals could not have been produced then otherwise than potentially.

6. In the words of Augustine (Super. Gen. contr. Manich. i): "If an unskilled person enters the workshop of an artificer he sees in it many appliances of which he does not understand the use, and which, if he is a foolish fellow, he considers unnecessary. Moreover, should he carelessly fall into the fire, or wound himself with a sharp-edged tool, he is under the impression that many of the things there are hurtful; whereas the craftsman, knowing their use, laughs at his folly. And thus some people presume to find fault with many things in this world, through not seeing the reasons for their existence. For though not required for the furnishing of our house, these things are necessary for the perfection of the universe." And, since man before he sinned would have used the things of this world conformably to the order designed, poisonous animals would not have injured him.



Question: 73 ON THE THINGS THAT BELONG TO THE SEVENTH DAY (THREE ARTICLES)





We must next consider the things that belong to the seventh day. Under this head there are three points of inquiry:

(1) About the completion of the works;

(2) About the resting of God;

(3) About the blessing and sanctifying of this day.



Article: 1 Whether the completion of the Divine works ought to be ascribed to the seventh day?




Objection: 1. It would seem that the completion of the Divine works ought not to be ascribed to the seventh day. For all things that are done in this world belong to the Divine works. But the consummation of the world will be at the end of the world (Mt 13,39-40). Moreover, the time of Christ's Incarnation is a time of completion, wherefore it is called "the time of fulness [*Vulg.: 'the fulness of time']" (Ga 4,4). And Christ Himself, at the moment of His death, cried out, "It is consummated" (Jn 19,30). Hence the completion of the Divine works does not belong to the seventh day.

2. Further, the completion of a work is an act in itself. But we do not read that God acted at all on the seventh day, but rather that He rested from all His work. Therefore the completion of the works does not belong to the seventh day.

3. Further, nothing is said to be complete to which many things are added, unless they are merely superfluous, for a thing is called perfect to which nothing is wanting that it ought to possess. But many things were made after the seventh day, as the production of many individual beings, and even of certain new species that are frequently appearing, especially in the case of animals generated from putrefaction. Also, God creates daily new souls. Again, the work of the Incarnation was a new work, of which it is said (Jr 31,22): "The Lord hath created a new thing upon the earth." Miracles also are new works, of which it is said (Qo 36,6): "Renew thy signs, and work new miracles." Moreover, all things will be made new when the Saints are glorified, according to Apoc. 21:5: "And He that sat on the throne said: Behold I make all things new." Therefore the completion of the Divine works ought not to be attributed to the seventh day.

On the contrary It is said (Gn 2,2): "On the seventh day God ended His work which He had made."

I answer that The perfection of a thing is twofold, the first perfection and the second perfection. The 'first' perfection is that according to which a thing is substantially perfect, and this perfection is the form of the whole; which form results from the whole having its parts complete. But the 'second' perfection is the end, which is either an operation, as the end of the harpist is to play the harp; or something that is attained by an operation, as the end of the builder is the house that he makes by building. But the first perfection is the cause of the second, because the form is the principle of operation. Now the final perfection, which is the end of the whole universe, is the perfect beatitude of the Saints at the consummation of the world; and the first perfection is the completeness of the universe at its first founding, and this is what is ascribed to the seventh day.

Reply to Objection: 1. The first perfection is the cause of the second, as above said. Now for the attaining of beatitude two things are required, nature and grace. Therefore, as said above, the perfection of beatitude will be at the end of the world. But this consummation existed previously in its causes, as to nature, at the first founding of the world, as to grace, in the Incarnation of Christ. For, "Grace and truth came by Jesus Christ" (Jn 1,17). So, then, on the seventh day was the consummation of nature, in Christ's Incarnation the consummation of grace, and at the end of the world will be the consummation of glory.

2. God did act on the seventh day, not by creating new creatures, but by directing and moving His creatures to the work proper to them, and thus He made some beginning of the "second" perfection. So that, according to our version of the Scripture, the completion of the works is attributed to the seventh day, though according to another it is assigned to the sixth. Either version, however, may stand, since the completion of the universe as to the completeness of its parts belongs to the sixth day, but its completion as regards their operation, to the seventh. It may also be added that in continuous movement, so long as any movement further is possible, movement cannot be called completed till it comes to rest, for rest denotes consummation of movement. Now God might have made many other creatures besides those which He made in the six days, and hence, by the fact that He ceased making them on the seventh day, He is said on that day to have consummated His work.

3. Nothing entirely new was afterwards made by God, but all things subsequently made had in a sense been made before in the work of the six days. Some things, indeed, had a previous experience materially, as the rib from the side of Adam out of which God formed Eve; whilst others existed not only in matter but also in their causes, as those individual creatures that are now generated existed in the first of their kind. Species, also, that are new, if any such appear, existed beforehand in various active powers; so that animals, and perhaps even new species of animals, are produced by putrefaction by the power which the stars and elements received at the beginning. Again, animals of new kinds arise occasionally from the connection of individuals belonging to different species, as the mule is the offspring of an ass and a mare; but even these existed previously in their causes, in the works of the six days. Some also existed beforehand by way of similitude, as the souls now created. And the work of the Incarnation itself was thus foreshadowed, for as we read (Ph 2,7), The Son of God "was made in the likeness of men." And again, the glory that is spiritual was anticipated in the angels by way of similitude; and that of the body in the heaven, especially the empyrean. Hence it is written (Qo 1,10), "Nothing under the sun is new, for it hath already gone before, in the ages that were before us."



Article: 2 Whether God rested on the seventh day from all His work?




Objection: 1. It would seem that God did not rest on the seventh day from all His work. For it is said (Jn 5,17), "My Father worketh until now, and I work." God, then, did not rest on the seventh day from all His work.

2. Further, rest is opposed to movement, or to labor, which movement causes. But, as God produced His work without movement and without labor, He cannot be said to have rested on the seventh day from His work.

3. Further, should it be said that God rested on the seventh day by causing man to rest; against this it may be argued that rest is set down in contradistinction to His work; now the words "God created" or "made" this thing or the other cannot be explained to mean that He made man create or make these things. Therefore the resting of God cannot be explained as His making man to rest.

On the contrary It is said (Gn 2,2): "God rested on the seventh day from all the work which He had done."

I answer that Rest is, properly speaking, opposed to movement, and consequently to the labor that arises from movement. But although movement, strictly speaking, is a quality of bodies, yet the word is applied also to spiritual things, and in a twofold sense. On the one hand, every operation may be called a movement, and thus the Divine goodness is said to move and go forth to its object, in communicating itself to that object, as Dionysius says (Div. Nom. ii). On the other hand, the desire that tends to an object outside itself, is said to move towards it. Hence rest is taken in two senses, in one sense meaning a cessation from work, in the other, the satisfying of desire. Now, in either sense God is said to have rested on the seventh day. First, because He ceased from creating new creatures on that day, for, as said above (Article [1], ad 3), He made nothing afterwards that had not existed previously, in some degree, in the first works; secondly, because He Himself had no need of the things that He had made, but was happy in the fruition of Himself. Hence, when all things were made He is not said to have rested "in" His works, as though needing them for His own happiness, but to have rested "from" them, as in fact resting in Himself, as He suffices for Himself and fulfils His own desire. And even though from all eternity He rested in Himself, yet the rest in Himself, which He took after He had finished His works, is that rest which belongs to the seventh day. And this, says Augustine, is the meaning of God's resting from His works on that day (Gn ad lit. iv).

Reply to Objection: 1. God indeed "worketh until now" by preserving and providing for the creatures He has made, but not by the making of new ones.

2. Rest is here not opposed to labor or to movement, but to the production of new creatures, and to the desire tending to an external object.

3. Even as God rests in Himself alone and is happy in the enjoyment of Himself, so our own sole happiness lies in the enjoyment of God. Thus, also, He makes us find rest in Himself, both from His works and our own. It is not, then, unreasonable to say that God rested in giving rest to us. Still, this explanation must not be set down as the only one, and the other is the first and principal explanation.



Article: 3 Whether blessing and sanctifying are due to the seventh day?




Objection: 1. It would seem that blessing and sanctifying are not due to the seventh day. For it is usual to call a time blessed or holy for that some good thing has happened in it, or some evil been avoided. But whether God works or ceases from work nothing accrues to Him or is lost to Him. Therefore no special blessing or sanctifying are due to the seventh day.

2. Further, the Latin "benedictio" [blessing] is derived from "bonitas" [goodness]. But it is the nature of good to spread and communicate itself, as Dionysius says (Div. Nom. iv). The days, therefore, in which God produced creatures deserved a blessing rather than the day on which He ceased producing them.

3. Further, over each creature a blessing was pronounced, as upon each work it was said, "God saw that it was good." Therefore it was not necessary that after all had been produced, the seventh day should be blessed.

On the contrary It is written (Gn 2,3), "God blessed the seventh day and sanctified it, because in it He had rested from all His work."

I answer that As said above (Article [2]), God's rest on the seventh day is understood in two ways. First, in that He ceased from producing new works, though He still preserves and provides for the creatures He has made. Secondly, in that after all His works He rested in Himself. According to the first meaning, then, a blessing befits the seventh day, since, as we explained (Question [72], ad 4), the blessing referred to the increase by multiplication; for which reason God said to the creatures which He blessed: "Increase and multiply." Now, this increase is effected through God's Providence over His creatures, securing the generation of like from like. And according to the second meaning, it is right that the seventh day should have been sanctified, since the special sanctification of every creature consists in resting in God. For this reason things dedicated to God are said to be sanctified.

Reply to Objection: 1. The seventh day is said to be sanctified not because anything can accrue to God, or be taken from Him, but because something is added to creatures by their multiplying, and by their resting in God.

2. In the first six days creatures were produced in their first causes, but after being thus produced, they are multiplied and preserved, and this work also belongs to the Divine goodness. And the perfection of this goodness is made most clear by the knowledge that in it alone God finds His own rest, and we may find ours in its fruition.

3. The good mentioned in the works of each day belongs to the first institution of nature; but the blessing attached to the seventh day, to its propagation.



Question: 74 ON ALL THE SEVEN DAYS IN COMMON (THREE ARTICLES)





We next consider all the seven days in common: and there are three points of inquiry:

(1) As to the sufficiency of these days;

(2) Whether they are all one day, or more than one?

(3) As to certain modes of speaking which Scripture uses in narrating the works of the six days.



Article: 1 Whether these days are sufficiently enumerated?




Objection: 1. It would seem that these days are not sufficiently enumerated. For the work of creation is no less distinct from the works of distinction and adornment than these two works are from one another. But separate days are assigned to distinction and to adornment, and therefore separate days should be assigned to creation.

2. Further, air and fire are nobler elements than earth and water. But one day is assigned to the distinction of water, and another to the distinction of the land. Therefore, other days ought to be devoted to the distinction of fire and air.

3. Further, fish differ from birds as much as birds differ from the beasts of the earth, whereas man differs more from other animals than all animals whatsoever differ from each other. But one day is devoted to the production of fishes, and another to that of the beast of the earth. Another day, then, ought to be assigned to the production of birds and another to that of man.

4. Further, it would seem, on the other hand, that some of these days are superfluous. Light, for instance, stands to the luminaries in the relation of accident to subject. But the subject is produced at the same time as the accident proper to it. The light and the luminaries, therefore, ought not to have been produced on different days.

5. Further, these days are devoted to the first instituting of the world. But as on the seventh day nothing was instituted, that day ought not to be enumerated with the others.

I answer that The reason of the distinction of these days is made clear by what has been said above (Question [70], Article [1]), namely, that the parts of the world had first to be distinguished, and then each part adorned and filled, as it were, by the beings that inhabit it. Now the parts into which the corporeal creation is divided are three, according to some holy writers, these parts being the heaven, or highest part, the water, or middle part, and the earth, or the lowest part. Thus the Pythagoreans teach that perfection consists in three things, the beginning, the middle, and the end. The first part, then, is distinguished on the first day, and adorned on the fourth, the middle part distinguished on the middle day, and adorned on the fifth, and the third part distinguished on the third day, and adorned on the sixth. But Augustine, while agreeing with the above writers as to the last three days, differs as to the first three, for, according to him, spiritual creatures are formed on the first day, and corporeal on the two others, the higher bodies being formed on the first these two days, and the lower on the second. Thus, then, the perfection of the Divine works corresponds to the perfection of the number six, which is the sum of its aliquot parts, one, two, three; since one day is assigned to the forming of spiritual creatures, two to that of corporeal creatures, and three to the work of adornment.

Reply to Objection: 1. According to Augustine, the work of creation belongs to the production of formless matter, and of the formless spiritual nature, both of which are outside of time, as he himself says (Confess. xii, 12). Thus, then, the creation of either is set down before there was any day. But it may also be said, following other holy writers, that the works of distinction and adornment imply certain changes in the creature which are measurable by time; whereas the work of creation lies only in the Divine act producing the substance of beings instantaneously. For this reason, therefore, every work of distinction and adornment is said to take place "in a day," but creation "in the beginning" which denotes something indivisible.

2. Fire and air, as not distinctly known by the unlettered, are not expressly named by Moses among the parts of the world, but reckoned with the intermediate part, or water, especially as regards the lowest part of the air; or with the heaven, to which the higher region of air approaches, as Augustine says (Gn ad lit. ii, 13).

3. The production of animals is recorded with reference to their adorning the various parts of the world, and therefore the days of their production are separated or united according as the animals adorn the same parts of the world, or different parts.

4. The nature of light, as existing in a subject, was made on the first day; and the making of the luminaries on the fourth day does not mean that their substance was produced anew, but that they then received a form that they had not before, as said above (Question [70], Article [1] ad 2).

5. According to Augustine (Gn ad lit. iv, 15), after all that has been recorded that is assigned to the six days, something distinct is attributed to the seventh---namely, that on it God rested in Himself from His works: and for this reason it was right that the seventh day should be mentioned after the six. It may also be said, with the other writers, that the world entered on the seventh day upon a new state, in that nothing new was to be added to it, and that therefore the seventh day is mentioned after the six, from its being devoted to cessation from work.



Article: 2 Whether all these days are one day?




Objection: 1. It would seem that all these days are one day. For it is written (Gn 2,4-5): "These are the generations of the heaven and the earth, when they were created, in the day that the Lord . . . made the heaven and the earth, and every plant of the field, before it sprung up in the earth." Therefore the day in which God made "the heaven and the earth, and every plant of the field," is one and the same day. But He made the heaven and the earth on the first day, or rather before there was any day, but the plant of the field He made on the third day. Therefore the first and third days are but one day, and for a like reason all the rest.

2. Further, it is said (Si 18,1): "He that liveth for ever, created all things together." But this would not be the case if the days of these works were more than one. Therefore they are not many but one only.

3. Further, on the seventh day God ceased from all new works. If, then, the seventh day is distinct from the other days, it follows that He did not make that day; which is not admissible.

4. Further, the entire work ascribed to one day God perfected in an instant, for with each work are the words (God) "said . . . . and it was . . . done." If, then, He had kept back His next work to another day, it would follow that for the remainder of a day He would have ceased from working and left it vacant, which would be superfluous. The day, therefore, of the preceding work is one with the day of the work that follows.

On the contrary It is written (Gn 1), "The evening and the morning were the second day . . . the third day," and so on. But where there is a second and third there are more than one. There was not, therefore, only one day.

I answer that On this question Augustine differs from other expositors. His opinion is that all the days that are called seven, are one day represented in a sevenfold aspect (Gn ad lit. iv, 22; De Civ. Dei xi, 9; Ad Orosium xxvi); while others consider there were seven distinct days, not one only. Now, these two opinions, taken as explaining the literal text of Genesis, are certainly widely different. For Augustine understands by the word "day," the knowledge in the mind of the angels, and hence, according to him, the first day denotes their knowledge of the first of the Divine works, the second day their knowledge of the second work, and similarly with the rest. Thus, then, each work is said to have been wrought in some one of these days, inasmuch as God wrought in some one of these days, inasmuch as God wrought nothing in the universe without impressing the knowledge thereof on the angelic mind; which can know many things at the same time, especially in the Word, in Whom all angelic knowledge is perfected and terminated. So the distinction of days denotes the natural order of the things known, and not a succession in the knowledge acquired, or in the things produced. Moreover, angelic knowledge is appropriately called "day," since light, the cause of day, is to be found in spiritual things, as Augustine observes (Gn ad lit. iv, 28). In the opinion of the others, however, the days signify a succession both in time, and in the things produced.

If, however, these two explanations are looked at as referring to the mode of production, they will be found not greatly to differ, if the diversity of opinion existing on two points, as already shown (Question [67], Article [1]; Question [69], Article [1]), between Augustine and other writers is taken into account. First, because Augustine takes the earth and the water as first created, to signify matter totally without form; but the making of the firmament, the gathering of the waters, and the appearing of dry land, to denote the impression of forms upon corporeal matter. But other holy writers take the earth and the water, as first created, to signify the elements of the universe themselves existing under the proper forms, and the works that follow to mean some sort of distinction in bodies previously existing, as also has been shown (Question [67], Articles [1],4; Question [69], Article [1]). Secondly, some writers hold that plants and animals were produced actually in the work of the six days; Augustine, that they were produced potentially. Now the opinion of Augustine, that the works of the six days were simultaneous, is consistent with either view of the mode of production. For the other writers agree with him that in the first production of things matter existed under the substantial form of the elements, and agree with him also that in the first instituting of the world animals and plants did not exist actually. There remains, however, a difference as to four points; since, according to the latter, there was a time, after the production of creatures, in which light did not exist, the firmament had not been formed, and the earth was still covered by the waters, nor had the heavenly bodies been formed, which is the fourth difference; which are not consistent with Augustine's explanation. In order, therefore, to be impartial, we must meet the arguments of either side.

Reply to Objection: 1. On the day on which God created the heaven and the earth, He created also every plant of the field, not, indeed, actually, but "before it sprung up in the earth," that is, potentially. And this work Augustine ascribes to the third day, but other writers to the first instituting of the world.

2. God created all things together so far as regards their substance in some measure formless. But He did not create all things together, so far as regards that formation of things which lies in distinction and adornment. Hence the word "creation" is significant.

3. On the seventh day God ceased from making new things, but not from providing for their increase, and to this latter work it belongs that the first day is succeeded by other days.

4. All things were not distinguished and adorned together, not from a want of power on God's part, as requiring time in which to work, but that due order might be observed in the instituting of the world. Hence it was fitting that different days should be assigned to the different states of the world, as each succeeding work added to the world a fresh state of perfection.

5. According to Augustine, the order of days refers to the natural order of the works attributed to the days.
