Whether the Son of God Assumed a Soul?
Objection 1: It would seem that the Son of God did not assume a soul.
For John has said, teaching the mystery of the Incarnation (John
1:14): "The Word was made flesh"--no mention being made of a soul.
Now it is not said that "the Word was made flesh" as if changed to
flesh, but because He assumed flesh. Therefore He seems not to have
assumed a soul.
Obj. 2: Further, a soul is necessary to the body, in order to quicken
it. But this was not necessary for the body of Christ, as it would
seem, for of the Word of God it is written (Ps. 35:10): Lord, "with
Thee is the fountain of life." Therefore it would seem altogether
superfluous for the soul to be there, when the Word was present. But
"God and nature do nothing uselessly," as the Philosopher says (De
Coel. i, 32; ii, 56). Therefore the Word would seem not to have
assumed a soul.
Obj. 3: Further, by the union of soul and body is constituted the
common nature, which is the human species. But "in the Lord Jesus
Christ we are not to look for a common species," as Damascene says
(De Fide Orth. iii, 3). Therefore He did not assume a soul.
_On the contrary,_ Augustine says (De Agone Christ. xxi): "Let us not
hearken to such as say that only a human body was assumed by the Word
of God; and take 'the Word was made flesh' to mean that the man had
no soul nor any other part of a man, save flesh."
_I answer that,_ As Augustine says (De Haeres. 69, 55), it was first
of all the opinion of Arius and then of Apollinaris that the Son of
God assumed only flesh, without a soul, holding that the Word took
the place of a soul to the body. And consequently it followed that
there were not two natures in Christ, but only one; for from a soul
and body one human nature is constituted. But this opinion cannot
hold, for three reasons. First, because it is counter to the
authority of Scripture, in which our Lord makes mention of His soul,
Matt. 26:38: "My soul is sorrowful even unto death"; and John 10:18:
"I have power to lay down My soul [_animam meam:_ Douay: 'My life']."
But to this Apollinaris replied that in these words soul is taken
metaphorically, in which way mention is made in the Old Testament of
the soul of God (Isa. 1:14): "My soul hateth your new moons and your
solemnities." But, as Augustine says (Qq. lxxxiii, qu. 80), the
Evangelists relate how Jesus wondered, was angered, sad, and hungry.
Now these show that He had a true soul, just as that He ate, slept
and was weary shows that He had a true human body: otherwise, if
these things are a metaphor, because the like are said of God in the
Old Testament, the trustworthiness of the Gospel story is undermined.
For it is one thing that things were foretold in a figure, and
another that historical events were related in very truth by the
Evangelists. Secondly, this error lessens the utility of the
Incarnation, which is man's liberation. For Augustine [*Vigilius
Tapsensis] argues thus (Contra Felician. xiii): "If the Son of God in
taking flesh passed over the soul, either He knew its sinlessness,
and trusted it did not need a remedy; or He considered it unsuitable
to Him, and did not bestow on it the boon of redemption; or He
reckoned it altogether incurable, and was unable to heal it; or He
cast it off as worthless and seemingly unfit for any use. Now two of
these reasons imply a blasphemy against God. For how shall we call
Him omnipotent, if He is unable to heal what is beyond hope? Or God
of all, if He has not made our soul. And as regards the other two
reasons, in one the cause of the soul is ignored, and in the other no
place is given to merit. Is He to be considered to understand the
cause of the soul, Who seeks to separate it from the sin of wilful
transgression, enabled as it is to receive the law by the endowment
of the habit of reason? Or how can His generosity be known to any one
who says it was despised on account of its ignoble sinfulness? If you
look at its origin, the substance of the soul is more precious than
the body: but if at the sin of transgression, on account of its
intelligence it is worse than the body. Now I know and declare that
Christ is perfect wisdom, nor have I any doubt that He is most
loving; and because of the first of these He did not despise what was
better and more capable of prudence; and because of the second He
protected what was most wounded." Thirdly, this position is against
the truth of the Incarnation. For flesh and the other parts of man
receive their species through the soul. Hence, if the soul is absent,
there are no bones nor flesh, except equivocally, as is plain from
the Philosopher (De Anima ii, 9; _Metaph._ vii, 34).
Reply Obj. 1: When we say, "The Word was made flesh," "flesh" is
taken for the whole man, as if we were to say, "The Word was made
man," as Isa. 40:5: "All flesh together shall see that the mouth of
the Lord hath spoken." And the whole man is signified by flesh,
because, as is said in the authority quoted, the Son of God became
visible by flesh; hence it is subjoined: "And we saw His glory." Or
because, as Augustine says (Qq. lxxxiii, qu. 80), "in all that union
the Word is the highest, and flesh the last and lowest. Hence,
wishing to commend the love of God's humility to us, the Evangelist
mentioned the Word and flesh, leaving the soul on one side, since it
is less than the Word and nobler than flesh." Again, it was
reasonable to mention flesh, which, as being farther away from the
Word, was less assumable, as it would seem.
Reply Obj. 2: The Word is the fountain of life, as the first
effective cause of life; but the soul is the principle of the life of
the body, as its form. Now the form is the effect of the agent. Hence
from the presence of the Word it might rather have been concluded
that the body was animated, just as from the presence of fire it may
be concluded that the body, in which fire adheres, is warm.
Reply Obj. 3: It is not unfitting, indeed it is necessary to say that
in Christ there was a nature which was constituted by the soul coming
to the body. But Damascene denied that in Jesus Christ there was a
common species, i.e. a third something resulting from the Godhead and
the humanity.
