Of the Beginning of the Duration of Creatures

Of the Beginning of the Duration of Creatures — St. Thomas Aquinas asks: Whether the universe of creatures always existed?; Whether it is an article of faith that the world began?; Whether the creation of things was in the beginning of time?.

Next must be considered the beginning of the duration of creatures, about which there are three points for treatment:

Article 1: Whether the universe of creatures always existed?

It is said (Jn. 17:5), "Glorify Me, O Father, with Thyself with the glory which I had before the world was"; and (Prov. 8:22), "The Lord possessed Me in the beginning of His ways, before He made anything from the beginning."

Nothing except God can be eternal. And this statement is far from impossible to uphold: for it has been shown above () that the will of God is the cause of things. Therefore things are necessary, according as it is necessary for God to will them, since the necessity of the effect depends on the necessity of the cause (Metaph. v, text 6). Now it was shown above (), that, absolutely speaking, it is not necessary that God should will anything except Himself. It is not therefore necessary for God to will that the world should always exist; but the world exists forasmuch as God wills it to exist, since the being of the world depends on the will of God, as on its cause. It is not therefore necessary for the world to be always; and hence it cannot be proved by demonstration.

Nor are Aristotle's reasons (Phys. viii) simply, but relatively, demonstrative---viz. in order to contradict the reasons of some of the ancients who asserted that the world began to exist in some quite impossible manner. This appears in three ways. Firstly, because, both in Phys. viii and in De Coelo i, text 101, he premises some opinions, as those of Anaxagoras, Empedocles and Plato, and brings forward reasons to refute them. Secondly, because wherever he speaks of this subject, he quotes the testimony of the ancients, which is not the way of a demonstrator, but of one persuading of what is probable. Thirdly, because he expressly says (Topic. i, 9), that there are dialectical problems, about which we have nothing to say from reason, as, "whether the world is eternal."

Article 2: Whether it is an article of faith that the world began?

The articles of faith cannot be proved demonstratively, because faith is of things "that appear not" (Heb. 11:1). But that God is the Creator of the world: hence that the world began, is an article of faith; for we say, "I believe in one God," etc. And again, Gregory says (Hom. i in Ezech.), that Moses prophesied of the past, saying, "In the beginning God created heaven and earth": in which words the newness of the world is stated. Therefore the newness of the world is known only by revelation; and therefore it cannot be proved demonstratively.

By faith alone do we hold, and by no demonstration can it be proved, that the world did not always exist, as was said above of the mystery of the Trinity (). The reason of this is that the newness of the world cannot be demonstrated on the part of the world itself. For the principle of demonstration is the essence of a thing. Now everything according to its species is abstracted from "here" and "now"; whence it is said that universals are everywhere and always. Hence it cannot be demonstrated that man, or heaven, or a stone were not always. Likewise neither can it be demonstrated on the part of the efficient cause, which acts by will. For the will of God cannot be investigated by reason, except as regards those things which God must will of necessity; and what He wills about creatures is not among these, as was said above (). But the divine will can be manifested by revelation, on which faith rests. Hence that the world began to exist is an object of faith, but not of demonstration or science. And it is useful to consider this, lest anyone, presuming to demonstrate what is of faith, should bring forward reasons that are not cogent, so as to give occasion to unbelievers to laugh, thinking that on such grounds we believe things that are of faith.

Article 3: Whether the creation of things was in the beginning of time?

It is said (Gn. 1:1): "In the beginning God created heaven and earth."

The words of Genesis, "In the beginning God created heaven and earth," are expounded in a threefold sense in order to exclude three errors. For some said that the world always was, and that time had no beginning; and to exclude this the words "In the beginning" are expounded---viz. "of time." And some said that there are two principles of creation, one of good things and the other of evil things, against which "In the beginning" is expounded---"in the Son." For as the efficient principle is appropriated to the Father by reason of power, so the exemplar principle is appropriated to the Son by reason of wisdom, in order that, as it is said (Ps. 103:24), "Thou hast made all things in wisdom," it may be understood that God made all things in the beginning---that is, in the Son; according to the word of the Apostle (Col. 1:16), "In Him"---viz. the Son---"were created all things." But others said that corporeal things were created by God through the medium of spiritual creation; and to exclude this it is expounded thus: "In the beginning"---i.e. before all things---"God created heaven and earth." For four things are stated to be created together---viz. the empyrean heaven, corporeal matter, by which is meant the earth, time, and the angelic nature.
