lity.

Obj. 3: Further, will is consequent upon nature, as was said (A. 1).
But in Christ there was only one nature besides the Divine. Hence in
Christ there was only one human will.

_On the contrary,_ Ambrose says (De Fide ii, 7): "Mine is the will
which He calls His own; because as Man He assumed my sorrow." From
this we are given to understand that sorrow pertains to the human
will of Christ. Now sorrow pertains to the sensuality, as was said in
the Second Part (I-II, Q. 23, A. 1; Q. 25, A. 1). Therefore,
seemingly, in Christ there is a will of sensuality besides the will
of reason.

_I answer that,_ As was said (Q. 9, A. 1), the Son of God assumed
human nature together with everything pertaining to the perfection of
human nature. Now in human nature is included animal nature, as the
genus in its species. Hence the Son of God must have assumed together
with the human nature whatever belongs to animal nature; one of which
things is the sensitive appetite, which is called the sensuality.
Consequently it must be allowed that in Christ there was a sensual
appetite, or sensuality. But it must be borne in mind that sensuality
or the sensual appetite, inasmuch as it naturally obeys reason, is
said to be "rational by participation," as is clear from the
Philosopher (Ethic. i, 13). And because "the will is in the reason,"
as stated above, it may equally be said that the sensuality is "a
will by participation."

Reply Obj. 1: This argument is based on the will, essentially so
called, which is only in the intellectual part; but the will by
participation can be in the sensitive part, inasmuch as it obeys
reason.

Reply Obj. 2: The sensuality is signified by the serpent--not as
regards the nature of the sensuality, which Christ assumed, but as
regards the corruption of the _fomes,_ which was not in Christ.

Reply Obj. 3: "Where there is one thing on account of another, there
seems to be only one" (Aristotle, _Topic._ iii); thus a surface which
is visible by color is one visible thing with the color. So, too,
because the sensuality is called the will, only because it partakes
of the rational will, there is said to be but one human will in
Christ, even as there is but one human nature.

Whether in Christ There Were Two Wills As Regards the Reason?

Objection 1: It would seem that in Christ there were two wills as
regards the reason. For Damascene says (De Fid
