appearance of law, though being framed by one who is in power, is derived from the eternal law; since all power is from the Lord God, according to Rom. 13:1.
Reply Obj. 3: Human law is said to permit certain things, not as approving them, but as being unable to direct them. And many things are directed by the Divine law, which human law is unable to direct, because more things are subject to a higher than to a lower cause. Hence the very fact that human law does not meddle with matters it cannot direct, comes under the ordination of the eternal law. It would be different, were human law to sanction what the eternal law condemns. Consequently it does not follow that human law is not derived from the eternal law, but that it is not on a perfect equality with it.
FOURTH ARTICLE [I-II, Q. 93, Art. 4]
Whether Necessary and Eternal Things Are Subject to the Eternal Law?
Objection 1: It would seem that necessary and eternal things are subject to the eternal law. For whatever is reasonable is subject to reason. But the Divine will is reasonable, for it is just. Therefore it is subject to (the Divine) reason. But the eternal law is the Divine reason. Therefore God's will is subject to the eternal law. But God's will is eternal. Therefore eternal and necessary things are subject to the eternal law.
Obj. 2: Further, whatever is subject to the King, is subject to the King's law. Now the Son, according to 1 Cor. 15:28, 24, "shall be subject . . . to God and the Father . . . when He shall have delivered up the Kingdom to Him." Therefore the Son, Who is eternal, is subject to the eternal law.
Obj. 3: Further, the eternal law is Divine providence as a type. But many necessary things are subject to Divine providence: for instance, the stability of incorporeal substances and of the heavenly bodies. Therefore even necessary things are subject to the eternal law.
On the contrary, Things that are necessary cannot be otherwise, and consequently need no restraining. But laws are imposed on men, in order to restrain them from evil, as explained above (Q. 92, A. 2). Therefore necessary things are not subject to the eternal law.
I answer that, As stated above (A. 1), the eternal law is the type of the Divine government. Consequently whatever is subject to the Divine government, is subject to the eternal law: while if anything is not subject to the Divine government, neither is it subject to the eternal law. The application of this distinction may be gathered by looking around us. For those things are subject to human government, which can be done by man; but what pertains to the nature of man is not subject to human government; for instance, that he should have a soul, hands, or feet. Accordingly all that is in things created by God, whether it be contingent or necessary, is subject to the eternal law: while things pertaining to the Divine Nature or Essence are not subject to the eternal law, but are the eternal law itself.
Reply Obj. 1: We may speak of God's will in two ways. First, as to the will itself: and thus, since God's will is His very Essence, it is subject neither to the Divine government, nor to the eternal law, but is the same thing as the eternal law. Secondly, we may speak of God's will, as to the things themselves that God wills about creatures; which things are subject to the eternal law, in so far as they are planned by Divine Wisdom. In reference to these things God's will is said to be reasonable (rationalis): though regarded in itself it should rather be called their type (ratio).
