Of the devil, the world, God, providence, man, and his wisdom
There follows a most senseless comparison. “As the builder,” he says, “when he is about to erect any building, does not himself make the materials, but uses those which are already prepared, and the statuary also the wax; so that divine providence ought to have had materials at hand, not of its own production, but already prepared for use.” Nay rather it ought not; for God will have less power if He makes from materials already provided, which is the part of man. The builder will erect nothing without wood, for he cannot make the wood itself; and not to be able to do this is the part of human weakness.
But God Himself makes the materials for Himself, because He has the power. For to have the power is the property of God; for if He is not able, He is not God. 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. Nor can anything be begun, or made, or completed, unless it shall have been foreseen by reason how it shall be made before it exists, and how it shall endure after it has been made.
In short, he only makes anything who has the will to make it, and hands to complete that which he has willed. But that which is insensible always lies inactive and torpid; nothing can originate in that source where there is no voluntary motion. For if every animal is possessed of reason, it is certain that it cannot be produced from that which is destitute of reason, nor can that which is not present in the original source be received from any other quarter. Nor, however, let it disturb any one, that certain animals appear to be born from the earth.
For the earth does not give birth to these of itself, but the Spirit of God, without which nothing is produced. Therefore God did not arise from matter, because a being endued with sensibility can never spring from one that is insensible, a wise one from one that is irrational, one that is incapable of suffering from one that can suffer, an incorporeal being from a corporeal one; but matter is rather from God. For whatever consists of a body solid, and capable of being handled, admits of an external force.
That which admits of force is capable of dissolution; that which is dissolved perishes; that which perishes must necessarily have had an origin; that which had an origin had a source from which it originated, that is, some maker, who is intelligent, foreseeing, and skilled in making. There is one assuredly, and that no other than God. And since He is possessed of sensibility, intelligence, providence, power, and vigour, He is able to create and make both animated and inanimate objects, because He has the means of making everything.
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. For that which is destroyed was previously built up; that which is loosened was previously bound up; that which is brought to an end was begun. If, then, it is inferred from its change and end, that matter had a beginning, from whom could that beginning have been, except from God?
God, therefore, is the only being who was not made; and therefore He can destroy other things, but He Himself cannot be destroyed. That which was in Him will always be permanent, because He has not been produced or sprung from any other source; nor does His birth depend on any other object, which being changed may cause His dissolution. He is of Himself, as we said in the first book; and therefore He is such as He willed that He should be, incapable of suffering, unchangeable, incorruptible, blessed, and eternal.
