Summa Th. I-II EN Qu.91 a.5
1825
Objection: 1. It would seem that there is but one Divine law. Because, where there is one king in one kingdom there is but one law. Now the whole of mankind is compared to God as to one king, according to Ps 46,8: "God is the King of all the earth." Therefore there is but one Divine law.
2. Further, every law is directed to the end which the lawgiver intends for those for whom he makes the law. But God intends one and the same thing for all men; since according to 1Tm 2,4: "He will have all men to be saved, and to come to the knowledge of the truth." Therefore there is but one Divine law.
3. Further, the Divine law seems to be more akin to the eternal law, which is one, than the natural law, according as the revelation of grace is of a higher order than natural knowledge. Therefore much more is the Divine law but one.
On the contrary The Apostle says (He 7,12): "The priesthood being translated, it is necessary that a translation also be made of the law." But the priesthood is twofold, as stated in the same passage, viz. the levitical priesthood, and the priesthood of Christ. Therefore the Divine law is twofold, namely the Old Law and the New Law.
I answer that As stated in the I 30,3, distinction is the cause of number. Now things may be distinguished in two ways. First, as those things that are altogether specifically different, e.g. a horse and an ox. Secondly, as perfect and imperfect in the same species, e.g. a boy and a man: and in this way the Divine law is divided into Old and New. Hence the Apostle (Ga 3,24-25) compares the state of man under the Old Law to that of a child "under a pedagogue"; but the state under the New Law, to that of a full grown man, who is "no longer under a pedagogue."Now the perfection and imperfection of these two laws is to be taken in connection with the three conditions pertaining to law, as stated above. For, in the first place, it belongs to law to be directed to the common good as to its end, as stated above (Question [90], Article [2]). This good may be twofold. It may be a sensible and earthly good; and to this, man was directly ordained by the Old Law: wherefore, at the very outset of the law, the people were invited to the earthly kingdom of the Chananaeans (Ex 3,8 Ex 3,17). Again it may be an intelligible and heavenly good: and to this, man is ordained by the New Law. Wherefore, at the very beginning of His preaching, Christ invited men to the kingdom of heaven, saying (Mt 4,17): "Do penance, for the kingdom of heaven is at hand." Hence Augustine says (Contra Faust. iv) that "promises of temporal goods are contained in the Old Testament, for which reason it is called old; but the promise of eternal life belongs to the New Testament."Secondly, it belongs to the law to direct human acts according to the order of righteousness (Article [4]): wherein also the New Law surpasses the Old Law, since it directs our internal acts, according to Mt 5,20: "Unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven." Hence the saying that "the Old Law restrains the hand, but the New Law controls the mind" ( Sentent. iii, D, xl).Thirdly, it belongs to the law to induce men to observe its commandments. This the Old Law did by the fear of punishment: but the New Law, by love, which is poured into our hearts by the grace of Christ, bestowed in the New Law, but foreshadowed in the Old. Hence Augustine says (Contra Adimant. Manich. discip. xvii) that "there is little difference [*The 'little difference' refers to the Latin words 'timor' and 'amor'---'fear' and 'love.'] between the Law and the Gospel---fear and love."
Reply to Objection: 1. As the father of a family issues different commands to the children and to the adults, so also the one King, God, in His one kingdom, gave one law to men, while they were yet imperfect, and another more perfect law, when, by the preceding law, they had been led to a greater capacity for Divine things.
2. The salvation of man could not be achieved otherwise than through Christ, according to Ac 4,12: "There is no other name . . . given to men, whereby we must be saved." Consequently the law that brings all to salvation could not be given until after the coming of Christ. But before His coming it was necessary to give to the people, of whom Christ was to be born, a law containing certain rudiments of righteousness unto salvation, in order to prepare them to receive Him.
3. The natural law directs man by way of certain general precepts, common to both the perfect and the imperfect: wherefore it is one and the same for all. But the Divine law directs man also in certain particular matters, to which the perfect and imperfect do not stand in the same relation. Hence the necessity for the Divine law to be twofold, as already explained.
1826
Objection: 1. It would seem that there is no law of the "fomes" of sin. For Isidore says (Etym. v) that the "law is based on reason." But the "fomes" of sin is not based on reason, but deviates from it. Therefore the "fomes" has not the nature of a law.
2. Further, every law is binding, so that those who do not obey it are called transgressors. But man is not called a transgressor, from not following the instigations of the "fomes"; but rather from his following them. Therefore the "fomes" has not the nature of a law.
3. Further, the law is ordained to the common good, as stated above (Question [90], Article [2]). But the "fomes" inclines us, not to the common, but to our own private good. Therefore the "fomes" has not the nature of sin.
On the contrary The Apostle says (Rm 7,23): "I see another law in my members, fighting against the law of my mind."
I answer that As stated above (Article [2]; Question [90], Article [1], ad 1), the law, as to its essence, resides in him that rules and measures; but, by way of participation, in that which is ruled and measured; so that every inclination or ordination which may be found in things subject to the law, is called a law by participation, as stated above (Article [2]; Question [90], Article [1], ad 1). Now those who are subject to a law may receive a twofold inclination from the lawgiver. First, in so far as he directly inclines his subjects to something; sometimes indeed different subjects to different acts; in this way we may say that there is a military law and a mercantile law. Secondly, indirectly; thus by the very fact that a lawgiver deprives a subject of some dignity, the latter passes into another order, so as to be under another law, as it were: thus if a soldier be turned out of the army, he becomes a subject of rural or of mercantile legislation.Accordingly under the Divine Lawgiver various creatures have various natural inclinations, so that what is, as it were, a law for one, is against the law for another: thus I might say that fierceness is, in a way, the law of a dog, but against the law of a sheep or another meek animal. And so the law of man, which, by the Divine ordinance, is allotted to him, according to his proper natural condition, is that he should act in accordance with reason: and this law was so effective in the primitive state, that nothing either beside or against reason could take man unawares. But when man turned his back on God, he fell under the influence of his sensual impulses: in fact this happens to each one individually, the more he deviates from the path of reason, so that, after a fashion, he is likened to the beasts that are led by the impulse of sensuality, according to Ps 48,21: "Man, when he was in honor, did not understand: he hath been compared to senseless beasts, and made like to them."So, then, this very inclination of sensuality which is called the "fomes," in other animals has simply the nature of a law (yet only in so far as a law may be said to be in such things), by reason of a direct inclination. But in man, it has not the nature of law in this way, rather is it a deviation from the law of reason. But since, by the just sentence of God, man is destitute of original justice, and his reason bereft of its vigor, this impulse of sensuality, whereby he is led, in so far as it is a penalty following from the Divine law depriving man of his proper dignity, has the nature of a law.
Reply to Objection: 1. This argument considers the "fomes" in itself, as an incentive to evil. It is not thus that it has the nature of a law, as stated above, but according as it results from the justice of the Divine law: it is as though we were to say that the law allows a nobleman to be condemned to hard labor for some misdeed.
2. This argument considers law in the light of a rule or measure: for it is in this sense that those who deviate from the law become transgressors. But the "fomes" is not a law in this respect, but by a kind of participation, as stated above.
3. This argument considers the "fomes" as to its proper inclination, and not as to its origin. And yet if the inclination of sensuality be considered as it is in other animals, thus it is ordained to the common good, namely, to the preservation of nature in the species or in the individual. And this is in man also, in so far as sensuality is subject to reason. But it is called "fomes" in so far as it strays from the order of reason.
1840
We must now consider the effects of law; under which head there are two points of inquiry:
(1) Whether an effect of law is to make men good?
(2) Whether the effects of law are to command, to forbid, to permit, and to punish, as the Jurist states?
1841
Objection: 1. It seems that it is not an effect of law to make men good. For men are good through virtue, since virtue, as stated in Ethic. ii, 6 is "that which makes its subject good." But virtue is in man from God alone, because He it is Who "works it in us without us," as we stated above (Question [55], Article [4]) in giving the definition of virtue. Therefore the law does not make men good.
2. Further, Law does not profit a man unless he obeys it. But the very fact that a man obeys a law is due to his being good. Therefore in man goodness is presupposed to the law. Therefore the law does not make men good.
3. Further, Law is ordained to the common good, as stated above (Question [90], Article [2]). But some behave well in things regarding the community, who behave ill in things regarding themselves. Therefore it is not the business of the law to make men good.
4. Further, some laws are tyrannical, as the Philosopher says (Polit. iii, 6). But a tyrant does not intend the good of his subjects, but considers only his own profit. Therefore law does not make men good.
On the contrary The Philosopher says (Ethic. ii, 1) that the "intention of every lawgiver is to make good citizens."
I answer that as stated above (Question [90], Article [1], ad 2; Articles [3],4), a law is nothing else than a dictate of reason in the ruler by whom his subjects are governed. Now the virtue of any subordinate thing consists in its being well subordinated to that by which it is regulated: thus we see that the virtue of the irascible and concupiscible faculties consists in their being obedient to reason; and accordingly "the virtue of every subject consists in his being well subjected to his ruler," as the Philosopher says (Polit. i). But every law aims at being obeyed by those who are subject to it. Consequently it is evident that the proper effect of law is to lead its subjects to their proper virtue: and since virtue is "that which makes its subject good," it follows that the proper effect of law is to make those to whom it is given, good, either simply or in some particular respect. For if the intention of the lawgiver is fixed on true good, which is the common good regulated according to Divine justice, it follows that the effect of the law is to make men good simply. If, however, the intention of the lawgiver is fixed on that which is not simply good, but useful or pleasurable to himself, or in opposition to Divine justice; then the law does not make men good simply, but in respect to that particular government. In this way good is found even in things that are bad of themselves: thus a man is called a good robber, because he works in a way that is adapted to his end.
Reply to Objection: 1. Virtue is twofold, as explained above (Question [63], Article [2]), viz. acquired and infused. Now the fact of being accustomed to an action contributes to both, but in different ways; for it causes the acquired virtue; while it disposes to infused virtue, and preserves and fosters it when it already exists. And since law is given for the purpose of directing human acts; as far as human acts conduce to virtue, so far does law make men good. Wherefore the Philosopher says in the second book of the Politics (Ethic. ii) that "lawgivers make men good by habituating them to good works."
2. It is not always through perfect goodness of virtue that one obeys the law, but sometimes it is through fear of punishment, and sometimes from the mere dictates of reason, which is a beginning of virtue, as stated above (Question [63], Article [1]).
3. The goodness of any part is considered in comparison with the whole; hence Augustine says (Confess. iii) that "unseemly is the part that harmonizes not with the whole." Since then every man is a part of the state, it is impossible that a man be good, unless he be well proportionate to the common good: nor can the whole be well consistent unless its parts be proportionate to it. Consequently the common good of the state cannot flourish, unless the citizens be virtuous, at least those whose business it is to govern. But it is enough for the good of the community, that the other citizens be so far virtuous that they obey the commands of their rulers. Hence the Philosopher says (Polit. ii, 2) that "the virtue of a sovereign is the same as that of a good man, but the virtue of any common citizen is not the same as that of a good man."
4. A tyrannical law, through not being according to reason, is not a law, absolutely speaking, but rather a perversion of law; and yet in so far as it is something in the nature of a law, it aims at the citizens' being good. For all it has in the nature of a law consists in its being an ordinance made by a superior to his subjects, and aims at being obeyed by them, which is to make them good, not simply, but with respect to that particular government.
1842
Objection: 1. It would seem that the acts of law are not suitably assigned as consisting in "command," "prohibition," "permission" and "punishment." For "every law is a general precept," as the jurist states. But command and precept are the same. Therefore the other three are superfluous.
2. Further, the effect of a law is to induce its subjects to be good, as stated above (Article [1]). But counsel aims at a higher good than a command does. Therefore it belongs to law to counsel rather than to command.
3. Further, just as punishment stirs a man to good deeds, so does reward. Therefore if to punish is reckoned an effect of law, so also is to reward.
4. Further, the intention of a lawgiver is to make men good, as stated above (Article [1]). But he that obeys the law, merely through fear of being punished, is not good: because "although a good deed may be done through servile fear, i.e. fear of punishment, it is not done well," as Augustine says (Contra duas Epist. Pelag. ii). Therefore punishment is not a proper effect of law.
On the contrary Isidore says (Etym. v, 19): "Every law either permits something, as: 'A brave man may demand his reward'": or forbids something, as: "No man may ask a consecrated virgin in marriage": or punishes, as: "Let him that commits a murder be put to death."
I answer that Just as an assertion is a dictate of reason asserting something, so is a law a dictate of reason, commanding something. Now it is proper to reason to lead from one thing to another. Wherefore just as, in demonstrative sciences, the reason leads us from certain principles to assent to the conclusion, so it induces us by some means to assent to the precept of the law.Now the precepts of law are concerned with human acts, in which the law directs, as stated above (Question [90], Articles [1],2; Question [91], Article [4]). Again there are three kinds of human acts: for, as stated above (Question [18], Article [8]), some acts are good generically, viz. acts of virtue; and in respect of these the act of the law is a precept or command, for "the law commands all acts of virtue" (Ethic. v, 1). Some acts are evil generically, viz. acts of vice, and in respect of these the law forbids. Some acts are generically indifferent, and in respect of these the law permits; and all acts that are either not distinctly good or not distinctly bad may be called indifferent. And it is the fear of punishment that law makes use of in order to ensure obedience: in which respect punishment is an effect of law.
Reply to Objection: 1. Just as to cease from evil is a kind of good, so a prohibition is a kind of precept: and accordingly, taking precept in a wide sense, every law is a kind of precept.
2. To advise is not a proper act of law, but may be within the competency even of a private person, who cannot make a law. Wherefore too the Apostle, after giving a certain counsel (1Co 7,12) says: "I speak, not the Lord." Consequently it is not reckoned as an effect of law.
3. To reward may also pertain to anyone: but to punish pertains to none but the framer of the law, by whose authority the pain is inflicted. Wherefore to reward is not reckoned an effect of law, but only to punish.
4. From becoming accustomed to avoid evil and fulfill what is good, through fear of punishment, one is sometimes led on to do so likewise, with delight and of one's own accord. Accordingly, law, even by punishing, leads men on to being good.
1860
We must now consider each law by itself; and (1) The eternal law; (2) The natural law; (3) The human law; (4) The old law; (5) The new law, which is the law of the Gospel. Of the sixth law which is the law of the "fomes," suffice what we have said when treating of original sin.
Concerning the first there are six points of inquiry:
(1) What is the eternal law?
(2) Whether it is known to all?
(3) Whether every law is derived from it?
(4) Whether necessary things are subject to the eternal law?
(5) Whether natural contingencies are subject to the eternal law?
(6) Whether all human things are subject to it?
1861
Objection: 1. It would seem that the eternal law is not a sovereign type existing in God. For there is only one eternal law. But there are many types of things in the Divine mind; for Augustine says (Qq. lxxxiii, qu. 46) that God "made each thing according to its type." Therefore the eternal law does not seem to be a type existing in the Divine mind.
2. Further, it is essential to a law that it be promulgated by word, as stated above (Question [90], Article [4]). But Word is a Personal name in God, as stated in the I 34,1: whereas type refers to the Essence. Therefore the eternal law is not the same as a Divine type.
3. Further, Augustine says (De Vera Relig. xxx): "We see a law above our minds, which is called truth." But the law which is above our minds is the eternal law. Therefore truth is the eternal law. But the idea of truth is not the same as the idea of a type. Therefore the eternal law is not the same as the sovereign type.
On the contrary Augustine says (De Lib. Arb. i, 6) that "the eternal law is the sovereign type, to which we must always conform."
I answer that Just as in every artificer there pre-exists a type of the things that are made by his art, so too in every governor there must pre-exist the type of the order of those things that are to be done by those who are subject to his government. And just as the type of the things yet to be made by an art is called the art or exemplar of the products of that art, so too the type in him who governs the acts of his subjects, bears the character of a law, provided the other conditions be present which we have mentioned above (Question [90]). Now God, by His wisdom, is the Creator of all things in relation to which He stands as the artificer to the products of his art, as stated in the I 14,8. Moreover He governs all the acts and movements that are to be found in each single creature, as was also stated in the I 103,5. Wherefore as the type of the Divine Wisdom, inasmuch as by It all things are created, has the character of art, exemplar or idea; so the type of Divine Wisdom, as moving all things to their due end, bears the character of law. Accordingly the eternal law is nothing else than the type of Divine Wisdom, as directing all actions and movements.
Reply to Objection: 1. Augustine is speaking in that passage of the ideal types which regard the proper nature of each single thing; and consequently in them there is a certain distinction and plurality, according to their different relations to things, as stated in the I 15,2. But law is said to direct human acts by ordaining them to the common good, as stated above (Question [90], Article [2]). And things, which are in themselves different, may be considered as one, according as they are ordained to one common thing. Wherefore the eternal law is one since it is the type of this order.
2. With regard to any sort of word, two points may be considered: viz. the word itself, and that which is expressed by the word. For the spoken word is something uttered by the mouth of man, and expresses that which is signified by the human word. The same applies to the human mental word, which is nothing else that something conceived by the mind, by which man expresses his thoughts mentally. So then in God the Word conceived by the intellect of the Father is the name of a Person: but all things that are in the Father's knowledge, whether they refer to the Essence or to the Persons, or to the works of God, are expressed by this Word, as Augustine declares (De Trin. xv, 14). And among other things expressed by this Word, the eternal law itself is expressed thereby. Nor does it follow that the eternal law is a Personal name in God: yet it is appropriated to the Son, on account of the kinship between type and word.
3. The types of the Divine intellect do not stand in the same relation to things, as the types of the human intellect. For the human intellect is measured by things, so that a human concept is not true by reason of itself, but by reason of its being consonant with things, since "an opinion is true or false according as it answers to the reality." But the Divine intellect is the measure of things: since each thing has so far truth in it, as it represents the Divine intellect, as was stated in the I 16,1. Consequently the Divine intellect is true in itself; and its type is truth itself.
1862
Objection: 1. It would seem that the eternal law is not known to all. Because, as the Apostle says (1Co 2,11), "the things that are of God no man knoweth, but the Spirit of God." But the eternal law is a type existing in the Divine mind. Therefore it is unknown to all save God alone.
2. Further, as Augustine says (De Lib. Arb. i, 6) "the eternal law is that by which it is right that all things should be most orderly." But all do not know how all things are most orderly. Therefore all do not know the eternal law.
3. Further, Augustine says (De Vera Relig. xxxi) that "the eternal law is not subject to the judgment of man." But according to Ethic. i, "any man can judge well of what he knows." Therefore the eternal law is not known to us.
On the contrary Augustine says (De Lib. Arb. i, 6) that "knowledge of the eternal law is imprinted on us."
I answer that A thing may be known in two ways: first, in itself; secondly, in its effect, wherein some likeness of that thing is found: thus someone not seeing the sun in its substance, may know it by its rays. So then no one can know the eternal law, as it is in itself, except the blessed who see God in His Essence. But every rational creature knows it in its reflection, greater or less. For every knowledge of truth is a kind of reflection and participation of the eternal law, which is the unchangeable truth, as Augustine says (De Vera Relig. xxxi). Now all men know the truth to a certain extent, at least as to the common principles of the natural law: and as to the others, they partake of the knowledge of truth, some more, some less; and in this respect are more or less cognizant of the eternal law.
Reply to Objection: 1. We cannot know the things that are of God, as they are in themselves; but they are made known to us in their effects, according to Rm 1,20: "The invisible things of God . . . are clearly seen, being understood by the things that are made."
2. Although each one knows the eternal law according to his own capacity, in the way explained above, yet none can comprehend it: for it cannot be made perfectly known by its effects. Therefore it does not follow that anyone who knows the eternal law in the way aforesaid, knows also the whole order of things, whereby they are most orderly.
3. To judge a thing may be understood in two ways. First, as when a cognitive power judges of its proper object, according to Jb 12,11: "Doth not the ear discern words, and the palate of him that eateth, the taste?" It is to this kind of judgment that the Philosopher alludes when he says that "anyone can judge well of what he knows," by judging, namely, whether what is put forward is true. In another way we speak of a superior judging of a subordinate by a kind of practical judgment, as to whether he should be such and such or not. And thus none can judge of the eternal law.
1863
Objection: 1. It would seem that not every law is derived from the eternal law. For there is a law of the "fomes," as stated above (Question [91], Article [6]), which is not derived from that Divine law which is the eternal law, since thereunto pertains the "prudence of the flesh," of which the Apostle says (Rm 8,7), that "it cannot be subject to the law of God." Therefore not every law is derived from the eternal law.
2. Further, nothing unjust can be derived from the eternal law, because, as stated above (Article [2], Objection [2]), "the eternal law is that, according to which it is right that all things should be most orderly." But some laws are unjust, according to Is 10,1: "Woe to them that make wicked laws." Therefore not every law is derived from the eternal law.
3. Further, Augustine says (De Lib. Arb. i, 5) that "the law which is framed for ruling the people, rightly permits many things which are punished by Divine providence." But the type of Divine providence is the eternal law, as stated above (Article [1]). Therefore not even every good law is derived from the eternal law.
On the contrary Divine Wisdom says (Pr 8,15): "By Me kings reign, and lawgivers decree just things." But the type of Divine Wisdom is the eternal law, as stated above (Article [1]). Therefore all laws proceed from the eternal law.
I answer that As stated above (Question [90], Articles [1],2), the law denotes a kind of plan directing acts towards an end. Now wherever there are movers ordained to one another, the power of the second mover must needs be derived from the power of the first mover; since the second mover does not move except in so far as it is moved by the first. Wherefore we observe the same in all those who govern, so that the plan of government is derived by secondary governors from the governor in chief; thus the plan of what is to be done in a state flows from the king's command to his inferior administrators: and again in things of art the plan of whatever is to be done by art flows from the chief craftsman to the under-crafts-men, who work with their hands. Since then the eternal law is the plan of government in the Chief Governor, all the plans of government in the inferior governors must be derived from the eternal law. But these plans of inferior governors are all other laws besides the eternal law. Therefore all laws, in so far as they partake of right reason, are derived from the eternal law. Hence Augustine says (De Lib. Arb. i, 6) that "in temporal law there is nothing just and lawful, but what man has drawn from the eternal law."
Reply to Objection: 1. The "fomes" has the nature of law in man, in so far as it is a punishment resulting from Divine justice; and in this respect it is evident that it is derived from the eternal law. But in so far as it denotes a proneness to sin, it is contrary to the Divine law, and has not the nature of law, as stated above (Question [91], Article [6]).
2. Human law has the nature of law in so far as it partakes of right reason; and it is clear that, in this respect, it is derived from the eternal law. But in so far as it deviates from reason, it is called an unjust law, and has the nature, not of law but of violence. Nevertheless even an unjust law, in so far as it retains some 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 Rm 13,1.
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.
1864
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.
2. Further, whatever is subject to the King, is subject to the King's law. Now the Son, according to 1Co 15,28 1Co 15,24, "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.
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 (Question [92], Article [2]). Therefore necessary things are not subject to the eternal law.
I answer that As stated above (Article [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 to Objection: 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].
2. God the Son was not made by God, but was naturally born of God. Consequently He is not subject to Divine providence or to the eternal law: but rather is Himself the eternal law by a kind of appropriation, as Augustine explains (De Vera Relig. xxxi). But He is said to be subject to the Father by reason of His human nature, in respect of which also the Father is said to be greater than He.
3. The third objection we grant, because it deals with those necessary things that are created.
4. As the Philosopher says (Metaph. v, text. 6), some necessary things have a cause of their necessity: and thus they derive from something else the fact that they cannot be otherwise. And this is in itself a most effective restraint; for whatever is restrained, is said to be restrained in so far as it cannot do otherwise than it is allowed to.
Summa Th. I-II EN Qu.91 a.5
