Philo of Alexandria On the Creation of the World; 26, 28, 31

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.

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.

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.
