Man produces his works out of that which already exists, because through his mortality he is weak, and through his weakness his power is limited and moderate; but God produces His works out of that which has no existence, because through His eternity He is strong, and through His strength His power is immense, which has no end or limit, like the life of the Maker Himself. What wonder, then, if God, when He was about to make the world, first prepared the material from which to make it, and prepared it out of that which had no existence? Because it is impossible for God to borrow anything from another source, inasmuch as all things are in Himself and from Himself. For if there is anything before Him, and if anything has been made, but not by Him, He will therefore lose both the power and the name of God.
But it may be said matter was never made, like God, who out of matter made this world. In that case, it follows that two eternal principles are established, and those indeed opposed to one another, which cannot happen without discord and destruction. For those things which have a contrary force and method must of necessity come into collision. In this manner it will be impossible that both should be eternal, if they are opposed to one another, because one must overpower the other. Therefore the nature of that which is eternal cannot be otherwise than simple, so that all things descended from that source as from a fountain. Therefore either God proceeded from matter, or matter from God. Which of these is more true, is easily understood. For of these two, one is endued with sensibility, the other is insensible. The power of making anything cannot exist, except in that which has sensibility, intelligence, reflection, and the power of motion.
But matter cannot always have existed, for if it had existed it would be incapable of change. For that which always was, does not cease always to be; and that which had no beginning must of necessity be without an end. Moreover, it is easier for that which had a beginning to be without an end, than for that which had no beginning, to have an end. Therefore if matter was not made, nothing can be made from it. But if nothing can be made from it, then matter itself can have no existence. For matter is that out of which something is made. But everything out of which anything is made, inasmuch as it has received the hand of the artificer, is destroyed, and begins to be some other thing. Therefore, since matter had an end, at the time when the
world was made out of it, it also had a beginning.
