I answer that, Not only is it impossible that anything should be created by God, but it is necessary to say that all things were created by God, as appears from what has been said (Q[44], A[1]). For when anyone makes one thing from another, this latter thing from which he makes is presupposed to his action, and is not produced by his action; thus the craftsman works from natural things, as wood or brass, which are caused not by the action of art, but by the action of nature. So also nature itself causes natural things as regards their form, but presupposes matter. If therefore God did only act from something presupposed, it would follow that the thing presupposed would not be caused by Him. Now it has been shown above (Q[44], AA[1],2), that nothing can be, unless it is from God, Who is the universal cause of all being. Hence it is necessary to say that God brings things into being from nothing.
Reply to Objection 1: Ancient philosophers, as is said above (Q[44], A[2]), considered only the emanation of particular effects from particular causes, which necessarily presuppose something in their action; whence came their common opinion that "nothing is made from nothing." But this has no place in the first emanation from the universal principle of things.
Reply to Objection 2: Creation is not change, except according to a mode of understanding. For change means that the same something should be different now from what it was previously. Sometimes, indeed, the same actual thing is different now from what it was before, as in motion according to quantity, quality and place; but sometimes it is the same being only in potentiality, as in substantial change, the subject of which is matter. But in creation, by which the whole substance of a thing is produced, the same thing can be taken as different now and before only according to our way of understanding, so that a thing is understood as first not existing at all, and afterwards as existing. But as action and passion coincide as to the substance of motion, and differ only according to diverse relations (Phys. iii, text 20,21), it must follow that when motion is withdrawn, only diverse relations remain in the Creator and in the creature. But because the mode of signification follows the mode of understanding as was said above (Q[13], A[1]), creation is signified by mode of change; and on this account it is said that to create is to make something from nothing. And yet "to make" and "to be made" are more suitable expressions here than "to change" and "to be changed," because "to make" and "to be made" import a relation of cause to the effect, and of effect to the cause, and imply change only as a consequence.
Reply to Objection 3: In things which are made without movement, to become and to be already made are simultaneous, whether such making is the term of movement, as illumination (for a thing is being illuminated and is illuminated at the same time) or whether it is not the term of movement, as the word is being made in the mind and is made at the same time. In these things what is being made, is; but when we speak of its being made, we mean that it is from another, and was not previously. Hence since creation is without movement, a thing is being created and is already created at the same time.
Reply to Objection 4: This objection proceeds from a false imagination, as if there were an infinite medium between nothing and being; which is plainly false. This false imagination comes from creation being taken to signify a change existing between two forms.
Whether creation is anything in the creature?
Objection 1: It would seem that creation is not anything in the creature. For as creation taken in a passive sense is attributed to the creature, so creation taken in an active sense is attributed to the Creator. But creation taken actively is not anything in the Creator, because otherwise it would follow that in God there would be something temporal. Therefore creation taken passively is not anything in the creature.
Objection 2: Further, there is no medium between the Creator and the creature. But creation is signified as the medium between them both: since it is not the Creator, as it is not eternal; nor is it the creature, because in that case it would be necessary for the same reason to suppose another creation to create it, and so on to infinity. Therefore creation is not anything in the creature.
Objection 3: Further, if creation is anything besides the created substance, it must be an accident belonging to it. But every accident is in a subject. Therefore a thing created would be the subject of creation, and so the same thing would be the subject and also the term of creation. This is impossible, because the subject is before the accident, and preserves the accident; while the term is after the action and passion whose term it is, and as soon as it exists, action and passion cease. Therefore creation itself is not any thing.
On the contrary, It is greater for a thing to be made according to its entire substance, than to be made according to its substantial or accidental form. But generation taken simply, or relatively, whereby anything is made according to the substantial or the accidental form, is something in the thing generated. Therefore much more is creation, whereby a thing is made according to its whole substance, something in the thing created.
I answer that, Creation places something in the thing created according to relation only; because what is created, is not made by movement, or by change. For what is made by movement or by change is made from something pre-existing. And this happens, indeed, in the particular productions of some beings, but cannot happen in the production of all being by the universal cause of all beings, which is God. Hence God by creation produces things without movement. Now when movement is removed from action and passion, only relation remains, as was said above (A[2], ad 2). Hence creation in the creature is only a certain relation to the Creator as to the principle of its being; even as in passion, which implies movement, is implied a relation to the principle of motion.
Reply to Objection 1: Creation signified actively means the divine action, which is God's essence, with a relation to the creature. But in God relation to the creature is not a real relation, but only a relation of reason; whereas the relation of the creature to God is a real relation, as was said above (Q[13], A[7]) in treating of the divine names.
Reply to Objection 2: Because creation is signified as a change, as was said above (A[2], ad 2), and change is a kind of medium between the mover and the moved, therefore also creation is signified as a medium between the Creator and the creature. Nevertheless passive creation is in the creature, and is a creature. Nor is there need of a further creation in its creation; because relations, or their entire nature being referred to something, are not referred by any other relations, but by themselves; as was also shown above (Q[42], A[1], ad 4), in treating of the equality of the Persons.
Reply to Objection 3: The creature is the term of creation as signifying a change, but is the subject of creation, taken as a real relation, and is prior to it in being, as the subject is to the accident. Nevertheless creation has a certain aspect of priority on the part of the object to which it is directed, which is the beginning of the creature. Nor is it necessary that as long as the creature is it should be created; because creation imports a relation of the creature to the Creator, with a certain newness or beginning.
Whether to be created belongs to composite and subsisting things?
Objection 1: It would seem that to be created does not belong to composite and subsisting things. For in the book, De Causis (prop. iv) it is said, "The first of creatures is being." But the being of a thing created is not subsisting. Therefore creation properly speaking does not belong to subsisting and composite things.
Objection 2: Further, whatever is created is from nothing. But composite things are not from nothing, but are the result of their own component parts. Therefore composite things are not created.
Objection 3: Further, what is presupposed in the second emanation is properly produced by the first: as natural generation produces the natural thing, which is presupposed in the operation of art. But the thing supposed in natural generation is matter. Therefore matter, and not the composite, is, properly speaking, that which is created.
On the contrary, It is said ( Gn. 1:1 ): "In the beginning God created heaven and earth." But heaven and earth are subsisting composite things. Therefore creation belongs to them.
I answer that, To be created is, in a manner, to be made, as was shown above (Q[44], A[2], ad 2,3). Now, to be made is directed to the being of a thing. Hence to be made and to be created properly belong to whatever being belongs; which, indeed, belongs properly to subsisting things, whether they are simple things, as in the case of separate substances, or composite, as in the case of material substances. For being belongs to that which has being---that is, to what subsists in its own being. But forms and accidents and the like are called beings, not as if they themselves were, but because something is by them; as whiteness is called a being, inasmuch as its subject is white by it. Hence, according to the Philosopher (Metaph. vii, text 2) accident is more properly said to be "of a being" than "a being." Therefore, as accidents and forms and the like non-subsisting things are to be said to co-exist rather than to exist, so they ought to be called rather "concreated" than "created" things; whereas, properly speaking, created things are subsisting beings.
Reply to Objection 1: In the proposition "the first of created things is being," the word "being" does not refer to the subject of creation, but to the proper concept of the object of creation. For a created thing is called created because it is a being, not because it is "this" being, since creation is the emanation of all being from the Universal Being, as was said above (A[1]). We use a similar way of speaking when we say that "the first visible thing is color," although, strictly speaking, the thing colored is what is seen.
Reply to Objection 2: Creation does not mean the building up of a composite thing from pre-existing principles; but it means that the "composite" is created so that it is brought into being at the same time with all its principles.
Reply to Objection 3: This reason does not prove that matter alone is created, but that matter does not exist except by creation; for creation is the production of the whole being, and not only matter.
Whether it belongs to God alone to create?
Objection 1: It would seem that it does not belong to God alone to create, because, according to the Philosopher (De Anima ii, text 34), what is perfect can make its own likeness. But immaterial creatures are more perfect than material creatures, which nevertheless can make their own likeness, for fire generates fire, and man begets man. Therefore an immaterial substance can make a substance like to itself. But immaterial substance can be made only by creation, since it has no matter from which to be made. Therefore a creature can create.
