Of the Fitness of the Incarnation

Of the Fitness of the Incarnation — St. Thomas Aquinas asks: Whether it was fitting that God should become incarnate?; Whether it was necessary for the restoration of the human race that the Word of God should become incarnate?; Whether, if man had not sinned, God would have become incarnate?; Whether God became incarnate in order to take away actual sin, rather than to take away original sin?; Whether it was fitting that God should become incarnate in the beginning of the human race?; Whether the Incarnation ought to have been put off till the end of the world?.

Concerning the first, three things occur to be considered: first, the fitness of the Incarnation; secondly, the mode of union of the Word Incarnate; thirdly, what follows this union.

Under the first head there are six points of inquiry:

Article 1: Whether it was fitting that God should become incarnate?

It would seem most fitting that by visible things the invisible things of God should be made known; for to this end was the whole world made, as is clear from the word of the Apostle (Rom. 1:20): "For the invisible things of God . . . are clearly seen, being understood by the things that are made." But, as Damascene says (De Fide Orth. iii, 1), by the mystery of the Incarnation are made known at once the goodness, the wisdom, the justice, and the power or might of God---"His goodness, for He did not despise the weakness of His own handiwork; His justice, since, on man's defeat, He caused the tyrant to be overcome by none other than man, and yet He did not snatch men forcibly from death; His wisdom, for He found a suitable discharge for a most heavy debt; His power, or infinite might, for there is nothing greater than for God to become incarnate . . ."

To each things, that is befitting which belongs to it by reason of its very nature; thus, to reason befits man, since this belongs to him because he is of a rational nature. But the very nature of God is goodness, as is clear from Dionysius (Div. Nom. i). Hence, what belongs to the essence of goodness befits God. But it belongs to the essence of goodness to communicate itself to others, as is plain from Dionysius (Div. Nom. iv). Hence it belongs to the essence of the highest good to communicate itself in the highest manner to the creature, and this is brought about chiefly by "His so joining created nature to Himself that one Person is made up of these three---the Word, a soul and flesh," as Augustine says (De Trin. xiii). Hence it is manifest that it was fitting that God should become incarnate.

Article 2: Whether it was necessary for the restoration of the human race that the Word of God should become incarnate?

What frees the human race from perdition is necessary for the salvation of man. But the mystery of the Incarnation is such; according to Jn. 3:16: "God so loved the world as to give His only-begotten Son, that whosoever believeth in Him may not perish, but may have life everlasting." Therefore it was necessary for man's salvation that God should become incarnate.

A thing is said to be necessary for a certain end in two ways. First, when the end cannot be without it; as food is necessary for the preservation of human life. Secondly, when the end is attained better and more conveniently, as a horse is necessary for a journey. In the first way it was not necessary that God should become incarnate for the restoration of human nature. For God with His omnipotent power could have restored human nature in many other ways. But in the second way it was necessary that God should become incarnate for the restoration of human nature. Hence Augustine says (De Trin. xii, 10): "We shall also show that other ways were not wanting to God, to Whose power all things are equally subject; but that there was not a more fitting way of healing our misery."

Now this may be viewed with respect to our "furtherance in good." First, with regard to faith, which is made more certain by believing God Himself Who speaks; hence Augustine says (De Civ. Dei xi, 2): "In order that man might journey more trustfully toward the truth, the Truth itself, the Son of God, having assumed human nature, established and founded faith." Secondly, with regard to hope, which is thereby greatly strengthened; hence Augustine says (De Trin. xiii): "Nothing was so necessary for raising our hope as to show us how deeply God loved us. And what could afford us a stronger proof of this than that the Son of God should become a partner with us of human nature?" Thirdly, with regard to charity, which is greatly enkindled by this; hence Augustine says (De Catech. Rudib. iv): "What greater cause is there of the Lord's coming than to show God's love for us?" And he afterwards adds: "If we have been slow to love, at least let us hasten to love in return." Fourthly, with regard to well-doing, in which He set us an example; hence Augustine says in a sermon (xxii de Temp.): "Man who might be seen was not to be followed; but God was to be followed, Who could not be seen. And therefore God was made man, that He Who might be seen by man, and Whom man might follow, might be shown to man." Fifthly, with regard to the full participation of the Divinity, which is the true bliss of man and end of human life; and this is bestowed upon us by Christ's humanity; for Augustine says in a sermon (xiii de Temp.): "God was made man, that man might be made God."

So also was this useful for our "withdrawal from evil." First, because man is taught by it not to prefer the devil to himself, nor to honor him who is the author of sin; hence Augustine says (De Trin. xiii, 17): "Since human nature is so united to God as to become one person, let not these proud spirits dare to prefer themselves to man, because they have no bodies." Secondly, because we are thereby taught how great is man's dignity, lest we should sully it with sin; hence Augustine says (De Vera Relig. xvi): "God has proved to us how high a place human nature holds amongst creatures, inasmuch as He appeared to men as a true man." And Pope Leo says in a sermon on the Nativity (xxi): "Learn, O Christian, thy worth; and being made a partner of the Divine nature, refuse to return by evil deeds to your former worthlessness." Thirdly, because, "in order to do away with man's presumption, the grace of God is commended in Jesus Christ, though no merits of ours went before," as Augustine says (De Trin. xiii, 17). Fourthly, because "man's pride, which is the greatest stumbling-block to our clinging to God, can be convinced and cured by humility so great," as Augustine says in the same place. Fifthly, in order to free man from the thraldom of sin, which, as Augustine says (De Trin. xiii, 13), "ought to be done in such a way that the devil should be overcome by the justice of the man Jesus Christ," and this was done by Christ satisfying for us. Now a mere man could not have satisfied for the whole human race, and God was not bound to satisfy; hence it behooved Jesus Christ to be both God and man. Hence Pope Leo says in the same sermon: "Weakness is assumed by strength, lowliness by majesty, mortality by eternity, in order that one and the same Mediator of God and men might die in one and rise in the other---for this was our fitting remedy. Unless He was God, He would not have brought a remedy; and unless He was man, He would not have set an example."

And there are very many other advantages which accrued, above man's apprehension.

Article 3: Whether, if man had not sinned, God would have become incarnate?

Augustine says (De Verb. Apost. viii, 2), expounding what is set down in Lk. 19:10, "For the Son of Man is come to seek and to save that which was lost"; "Therefore, if man had not sinned, the Son of Man would not have come." And on 1 Tim. 1:15, "Christ Jesus came into this world to save sinners," a gloss says, "There was no cause of Christ's coming into the world, except to save sinners. Take away diseases, take away wounds, and there is no need of medicine."

There are different opinions about this question. For some say that even if man had not sinned, the Son of Man would have become incarnate. Others assert the contrary, and seemingly our assent ought rather to be given to this opinion.

For such things as spring from God's will, and beyond the creature's due, can be made known to us only through being revealed in the Sacred Scripture, in which the Divine Will is made known to us. Hence, since everywhere in the Sacred Scripture the sin of the first man is assigned as the reason of the Incarnation, it is more in accordance with this to say that the work of the Incarnation was ordained by God as a remedy for sin; so that, had sin not existed, the Incarnation would not have been. And yet the power of God is not limited to this; even had sin not existed, God could have become incarnate.

Article 4: Whether God became incarnate in order to take away actual sin, rather than to take away original sin?

It is written (Jn. 1:29): "Behold the Lamb of God, behold Him Who taketh away the sins [Vulg.: 'sin'] of the world."

It is certain that Christ came into this world not only to take away that sin which is handed on originally to posterity, but also in order to take away all sins subsequently added to it; not that all are taken away (and this is from men's fault, inasmuch as they do not adhere to Christ, according to Jn. 3:19: "The light is come into the world, and men loved darkness rather than the light"), but because He offered what was sufficient for blotting out all sins. Hence it is written (Rom. 5:15-16): "But not as the offense, so also the gift . . . For judgment indeed was by one unto condemnation, but grace is of many offenses unto justification."

Moreover, the more grievous the sin, the more particularly did Christ come to blot it out. But "greater" is said in two ways: in one way "intensively," as a more intense whiteness is said to be greater, and in this way actual sin is greater than original sin; for it has more of the nature of voluntary, as has been shown (). In another way a thing is said to be greater "extensively," as whiteness on a greater superficies is said to be greater; and in this way original sin, whereby the whole human race is infected, is greater than any actual sin, which is proper to one person. And in this respect Christ came principally to take away original sin, inasmuch as "the good of the race is a more Divine thing than the good of an individual," as is said Ethic. i, 2.

Article 5: Whether it was fitting that God should become incarnate in the beginning of the human race?

It is written (Gal. 4:4): "But when the fulness of the time was come, God sent His Son, made of a woman, made under the law": upon which a gloss says that "the fulness of the time is when it was decreed by God the Father to send His Son." But God decreed everything by His wisdom. Therefore God became incarnate at the most fitting time; and it was not fitting that God should become incarnate at the beginning of the human race.

Since the work of the Incarnation is principally ordained to the restoration of the human race by blotting out sin, it is manifest that it was not fitting for God to become incarnate at the beginning of the human race before sin. For medicine is given only to the sick. Hence our Lord Himself says (Mat. 9:12,13): "They that are in health need not a physician, but they that are ill . . . For I am not come to call the just, but sinners."

Nor was it fitting that God should become incarnate immediately after sin. First, on account of the manner of man's sin, which had come of pride; hence man was to be liberated in such a manner that he might be humbled, and see how he stood in need of a deliverer. Hence on the words in Gal. 3:19, "Being ordained by angels in the hand of a mediator," a gloss says: "With great wisdom was it so ordered that the Son of Man should not be sent immediately after man's fall. For first of all God left man under the natural law, with the freedom of his will, in order that he might know his natural strength; and when he failed in it, he received the law; whereupon, by the fault, not of the law, but of his nature, the disease gained strength; so that having recognized his infirmity he might cry out for a physician, and beseech the aid of grace."

Secondly, on account of the order of furtherance in good, whereby we proceed from imperfection to perfection. Hence the Apostle says (1 Cor. 15:46,47): "Yet that was not first which is spiritual, but that which is natural; afterwards that which is spiritual . . . The first man was of the earth, earthy; the second man from heaven, heavenly."

Thirdly, on account of the dignity of the incarnate Word, for on the words (Gal. 4:4), "But when the fulness of the time was come," a gloss says: "The greater the judge who was coming, the more numerous was the band of heralds who ought to have preceded him."

Fourthly, lest the fervor of faith should cool by the length of time, for the charity of many will grow cold at the end of the world. Hence (Lk. 18:8) it is written: "But yet the Son of Man, when He cometh, shall He find think you, faith on earth?"

Article 6: Whether the Incarnation ought to have been put off till the end of the world?

It is written (Hab. 3:2): "In the midst of the years Thou shalt make it known." Therefore the mystery of the Incarnation which was made known to the world ought not to have been put off till the end of the world.

As it was not fitting that God should become incarnate at the beginning of the world, so also it was not fitting that the Incarnation should be put off till the end of the world. And this is shown first from the union of the Divine and human nature. For, as it has been said (), perfection precedes imperfection in time in one way, and contrariwise in another way imperfection precedes perfection. For in that which is made perfect from being imperfect, imperfection precedes perfection in time, whereas in that which is the efficient cause of perfection, perfection precedes imperfection in time. Now in the work of the Incarnation both concur; for by the Incarnation human nature is raised to its highest perfection; and in this way it was not becoming that the Incarnation should take place at the beginning of the human race. And the Word incarnate is the efficient cause of the perfection of human nature, according to Jn. 1:16: "Of His fulness we have all received"; and hence the work of the Incarnation ought not to have been put off till the end of the world. But the perfection of glory to which human nature is to be finally raised by the Word Incarnate will be at the end of the world.

Secondly, from the effect of man's salvation; for, as is said Qq. Vet et Nov. Test., qu. 83, "it is in the power of the Giver to have pity when, or as much as, He wills. Hence He came when He knew it was fitting to succor, and when His boons would be welcome. For when by the feebleness of the human race men's knowledge of God began to grow dim and their morals lax, He was pleased to choose Abraham as a standard of the restored knowledge of God and of holy living; and later on when reverence grew weaker, He gave the law to Moses in writing; and because the gentiles despised it and would not take it upon themselves, and they who received it would not keep it, being touched with pity, God sent His Son, to grant to all remission of their sin and to offer them, justified, to God the Father." But if this remedy had been put off till the end of the world, all knowledge and reverence of God and all uprightness of morals would have been swept away from the earth.

Thirdly, this appears fitting to the manifestation of the Divine power, which has saved men in several ways---not only by faith in some future thing, but also by faith in something present and past.
