FIRST ARTICLE: WHETHER HUMAN NATURE WAS MORE ASSUMABLE BY THE SON OF GOD THAN ANY OTHER NATURE

State of the question. The inquiry concerns human nature as assumable, not according to its natural passive power nor according to its obediential power,[687] but according to its fitness.[688] The more common opinion among theologians affirms with St. Thomas[689] that according to God's absolute power any other nature is assumable. The discussion here concerns only its fitness.

This question is of some importance in determining whether besides the obediential power there is a fitness attached to the nature, but not necessarily so, for example, a fitness of assumption in the human nature rather than in the angelic.

First objection. The difficulty is that God's absolute power is not limited to one nature; for just as there is no such thing actually as the best of all possible worlds, so there is no created nature that is more fitted for the hypostatic union.

Second objection. The difficulty is that also in irrational creatures there is a trace of God's image.

Third objection. In the angelic nature we find a more perfect likeness of God than in the human nature, and there is need of redemption for angels that are sinners.

Fourth objection. Finally the whole universe is more capable of assumption than the human nature.

Conclusion. It was more fitting, says St. Thomas, for the human nature to be assumed by the Word, than any other nature.

Authoritative proof. This fittingness is intimated in various passages of Scripture. Thus the Wisdom of God is represented as saying: "My delights were to be with the children of men."[690] Similarly St. Paul writes: "For it became Him, for whom are all things, and by whom are all things, who had brought many children into glory, to perfect the author of their salvation, by His passion.... For nowhere doth He take hold of the angels, but of the seed of Abraham He taketh hold. Wherefore it behooved Him in all things to be made like unto His brethren, that He might become a merciful and faithful high priest before God, that He might be a propitiation for the sins of the people."[691] Christ had to be both priest and victim because no other victim was worthy of fulfilling this role.

Theological proof. It may be reduced to the following syllogism.

This greater fitness may be viewed both according to the dignity and the necessity or need of the assumable nature.

But the human is more worthy than the irrational nature since it can attain to union with the Word by knowledge and love.[692] Moreover, it needed reparation, since it was subjected to original sin, which is not true of the angels, for all did not sin, and those who did are already confirmed in their sin and incapable of redemption. Therefore it was more fitting for the human nature than any other nature to be assumed by the Word. This conclusion must be understood in the sense given by St. Thomas at the end of the argumentative part of this article, where he says: "Hence it follows that only human nature was assumable."

Moreover, as St. Thomas remarks in another of his works,[693] the human nature is a quasi-compendium of the universe, a microcosm, inasmuch as it contains within itself being, as in minerals, life as in the lower forms of living animals, intelligence as in the angels, although in not so perfect a way.

The solution of the difficulties raised in the objections confirms this last observation of St. Thomas.

Reply to first objection. Here it is shown that besides the obediential power, which includes everything that is not in itself repugnant to reason, there can be a certain fitness or congruity in the human nature for its being assumed by the Word in the hypostatic union, a fitness that is not found either in stones, plants, a lamb, or a dove. Hence St. Thomas says in this reply: "Therefore a creature is said to be not assumable, not as if we withdrew anything from the power of God, but in order to show the condition of the creature which has no capability for this." Therefore this capability, which is in neither stone nor dove, is not this obediential power for assumption, which is in either a stone or in any animal, for example, in the most spotless lamb.

As Cajetan remarks, St. Thomas did not ask whether the Word can assume the nature of a stone. There is nothing intrinsically impossible in this according to God's purely absolute power, but there would be no end or purpose in doing this. Thus God can by His purely absolute power annihilate the Blessed Virgin Mary, but there is no reason for doing so on the part of the end in view. Therefore this is repugnant, if not by God's purely absolute power, at least by His ordained power, either ordinary or extraordinary.

Yet there is truly in the nature of either a stone, a lamb, or a dove a non-repugnance or obediential power for the hypostatic union, although there is no capability in the sense of congruity.

From this reply to the first objection, it seems to follow that the capability or fitness of our nature to be elevated to the beatific vision is not this obediential power, which of itself requires nothing else but a non-repugnance to this elevation, inasmuch as God can do whatever is not repugnant. In fact, as will be stated farther on, there is in the most holy soul of Christ the obediential power for a greater degree of the light of glory.[694] The obediential power of our intellect is in itself unrestricted, because our intellect by God's absolute power, can always be raised to a higher degree of the light of glory, and our will to a higher degree of charity.

There remains this obediential power in the nature of the damned for being raised to the beatific vision, but it is no longer any fittingness in them.

Reply to second objection. "The irrational creature which falls short of the union with God by operation has no fitness to be united with Him in personal being."

Reply to third objection. Concerning the reply to this third objection, which must be real, Cajetan observes against Scotus, that for St. Thomas personality is something positive and real that is distinct from the individualized nature, for instance, from Michaelness, because St. Thomas says: "In this way, nothing pre-existing would be corrupted in it,"[695] if God, by producing a new angelic nature, were to unite it to Himself.

In this same reply, it is pointed out that the bad angels fell irreparably, though not indeed absolutely, but according to the way that is consistent with divine providence, as already explained by St. Thomas, for, when asking whether the will of the demons is confirmed in evil, he says: "The angel's free will is flexible to either opposite before the choice, but not after."[696] This means that the angel's choice elicited by means of intuitive and simultaneous knowledge of those things that must be considered in the object, is irrevocable, and thus it participates in the immutability of the divine choice, which is both most free and absolutely immutable. On the contrary, our choice is elicited by means of abstractive and discursive knowledge, which only gradually acquires the knowledge of all those things that must be considered. Hence it is revocable, inasmuch as after the choice we can consider certain new things not previously considered.[697]

Hence man is capable of redemption, but not the angel. Moreover, the first man was tempted by the devil and fell, whereas the devil fell solely by his own will. Hence the human nature is more worthy of compassion than the nature of the fallen angel.

First doubt. Can an irrational nature, such as that of a lamb or dove, be united befittingly with the person of the Word?

Reply. Several theologians give an affirmative answer, just as it was not unbecoming for the Word incarnate to be scourged, spit upon, and to die. In fact, during the three days of death, the Word remained hypostatically united to the corpse, not personally, but subsistentially. But these reasons do not rest on solid grounds, for the Word was united to the corpse of Christ, only because it was previously united to His human nature, and, if the Word was scourged and crucified, this was meritorious for our redemption. Whereas there is no comparison in the above-mentioned hypothesis, because the dove and the lamb are incapable of meriting and satisfying.

Second doubt. St. Thomas says in various passages that suppositum and nature are the same in the angels;[698] yet in his reply here[699] he holds that the angelic nature is assumable, which cannot be unless it is distinct from the suppositum.

Reply. Cajetan, Medina, Alvarez, Gonet, and Billuart say that St. Thomas in the passage cited above[700] means that the angelic nature is not distinct from its individualizing notes; but he holds that the angel has its own subsistence or personality that is distinct from its nature, which it would lose if the angelic nature were united with the Word. On several occasions St. Thomas says that there is a difference between what is (suppositum), and being (existence).[701] For it is manifest that Michael has not only his nature or Michaelness, but also his being and accidents, such as successive intellections and volitions.
