Our conclusion about the first is easily deduced from the nature of God's will, which is only distinguished from His understanding in relation to our intellect--that is, the will and the understanding of God are in reality one and the same, and are only distinguished in relation to our thoughts which we form concerning God's understanding. For instance, if we are only looking to the fact that the nature of a triangle is from eternity contained in the Divine nature as an eternal verity, we say that God possesses the idea of a triangle, or that He understands the nature of a triangle; but if afterwards we look to the fact that the nature of a triangle is thus contained in the Divine nature, solely by the necessity of the Divine nature, and not by the necessity of the nature and essence of a triangle--in fact, that the necessity of a triangle's essence and nature, in so far as they are conceived of as eternal verities, depends solely on the necessity of the Divine nature and intellect, we then style God's will or decree, that which before we styled His intellect. Wherefore we make one and the same affirmation concerning God when we say that He has from eternity decreed that three angles of a triangle are equal to two right angles, as when we say that He has understood it. Hence the affirmations and the negations of God always involve necessity or truth; so that, for example, if God said to Adam that He did not wish him to eat of the tree of knowledge of good and evil, it would have involved a contradiction that Adam should have been able to eat of it, and would therefore have been impossible that he should have so eaten, for the Divine command would have involved an eternal necessity and truth. But since Scripture nevertheless narrates that God did give this command to Adam, and yet that none the less Adam ate of the tree, we must perforce say that God revealed to Adam the evil which would surely follow if he should eat of the tree, but did not disclose that such evil would of necessity come to pass. Thus it was that Adam took the revelation to be not an eternal and necessary truth, but a law--that is, an ordinance followed by gain or loss, not depending necessarily on the nature of the act performed, but solely on the will and absolute power of some potentate, so that the revelation in question was solely in relation to Adam, and solely through his lack of knowledge a law, and God was, as it were, a lawgiver and potentate. From the same cause, namely, from lack of knowledge, the Decalogue in relation to the Hebrews was a law, for since they knew not the existence of God as an eternal truth, they must have taken as a law that which was revealed to them in the Decalogue, namely, that God exists, and that God only should be worshiped. But if God had spoken to them without the intervention of any bodily means, immediately they would have perceived it not as a law but as an eternal truth.
