VII. (26) Moses says also; “In the beginning God created the heaven and the earth:” taking the beginning to be, not as some men think, that which is according to time; for before the world time had no existence, but was created either simultaneously with it, or after it; for since time is the interval of the motion of the heavens, there could not have been any such thing as motion before there was anything which could be moved; but it follows of necessity that it received existence subsequently or simultaneously. It therefore follows also of necessity, that time was created either at the same moment with the world, or later than it–and to venture to assert that it is older than the world is absolutely inconsistent with philosophy. (27) But if the beginning spoken of by Moses is not to be looked upon as spoken of according to time, then it may be natural to suppose that it is the beginning according to number that is indicated; so that, “In the beginning he created,” is equivalent to “first of all he created the heaven;” for it is natural in reality that that should have been the first object created, being both the best of all created things, and being also made of the purest substance, because it was destined to be the most holy abode of the visible Gods who are perceptible by the external senses; (28) for if the Creator had made everything at the same moment, still those things which were created in beauty would no less have had a regular arrangement, for there is no such thing as beauty in disorder. But order is a due consequence and connection of things precedent and subsequent, if not in the completion of a work, at all events in the intention of the maker; for it is owing to order that they become accurately defined and stationary, and free from confusion. (29) In the first place therefore, from the model of the world, perceptible only by intellect, the Creator made an incorporeal heaven, and an invisible earth, and the form of air and of empty space: the former of which he called darkness, because the air is black by nature; and the other he called the abyss, for empty space is very deep and yawning with immense width. Then he created the incorporeal substance of water and of air, and above all he spread light, being the seventh thing made; and this again was incorporeal, and a model of the sun, perceptible only to intellect, and of all the lightgiving stars, which are destined to stand together in heaven.

VIII. (30) And air and light he considered worthy of the pre-eminence. For the one he called the breath of God, because it is air, which is the most life-giving of things, and of life the causer is God; and the other he called light, because it is surpassingly beautiful: for that which is perceptible only by intellect is as far more brilliant and splendid than that which is seen, as I conceive, the sun is than darkness, or day than night, or the intellect than any other of the outward senses by which men judge (inasmuch as it is the guide of the entire soul), or the eyes than any other part of the body. (31) And the invisible divine reason, perceptible only by intellect, he calls the image of God. And the image of this image is that light, perceptible only by the intellect, which is the image of the divine reason, which has explained its generation. And it is a star above the heavens, the source of those stars which are perceptible by the external senses, and if any one were to call it universal light he would not be very wrong; since it is from that the sun and the moon, and all the other planets and fixed stars derive their due light, in proportion as each has power given to it; that unmingled and pure light being obscured when it begins to change, according to the change from that which is perceptible only by the intellect, to that which is perceptible by the external senses; for none of those things which are perceptible to the external senses is pure.
