Thomas Aquinas - Summa Theologica, Part III (Tertia Pars)

SECOND ARTICLE [III, Q. 18, Art. 2]

Whether in Christ There Was a Will of Sensuality Besides the Will of

Reason?

Objection 1: It would seem that in Christ there was no will of sensuality besides the will of reason. For the Philosopher says (De Anima iii, text. 42) that "the will is in the reason, and in the sensitive appetite are the irascible and concupiscible parts." Now sensuality signifies the sensitive appetite. Hence in Christ there was no will of sensuality.

Obj. 2: Further, according to Augustine (De Trin. xii, 12, 13) the sensuality is signified by the serpent. But there was nothing serpent-like in Christ; for He had the likeness of a venomous animal without the venom, as Augustine says (De Pecc. Merit. et Remiss. i, 32). Hence in Christ there was no will of sensuality.

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. _______________________

THIRD ARTICLE [III, Q. 18, Art. 3]

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 Fide Orth. ii, 22) that there is a double will in man, viz. the natural will which is called thelesis , and the rational will which is called boulesis . Now Christ in His human nature had whatever belongs to the perfection of human nature. Hence both the foregoing wills were in Christ.

Obj. 2: Further, the appetitive power is diversified in man by the difference of the apprehensive power, and hence according to the difference of sense and intellect is the difference of sensitive and intellective appetite in man. But in the same way as regards man's apprehension, we hold the difference of reason and intellect; both of which were in Christ. Therefore there was a double will in Him, one intellectual and the other rational.

Obj. 3: Further, some [*Hugh of St. Victor, De Quat. Volunt. Christ.] ascribe to Christ "a will of piety," which can only be on the part of reason. Therefore in Christ on the part of reason there are several wills.

On the contrary, In every order there is one first mover. But the will is the first mover in the genus of human acts. Therefore in one man there is only one will, properly speaking, which is the will of reason. But Christ is one man. Therefore in Christ there is only one human will.

I answer that, As stated above (A. 1, ad 3), the will is sometimes taken for the power, and sometimes for the act. Hence if the will is taken for the act, it is necessary to place two wills, i.e. two species of acts of the will in Christ on the part of the reason. For the will, as was said in the I-II, Q. 8, AA. 2, 3, regards both the end and the means; and is affected differently towards both. For towards the end it is borne simply and absolutely, as towards what is good in itself; but towards the means it is borne under a certain relation, as the goodness of the means depends on something else. Hence the act of the will, inasmuch as it is drawn to anything desired of itself, as health, which act is called by Damascene thelesis —i.e. simple will, and by the masters "will as nature," is different from the act of the will as it is drawn to anything that is desired only in order to something else, as to take medicine; and this act of the will Damascene calls boulesis —i.e. counseling will, and the masters, "will as reason." But this diversity of acts does not diversify the power, since both acts regard the one common ratio of the object, which is goodness. Hence we must say that if we are speaking of the power of the will, in Christ there is but one human will, essentially so called and not by participation; but if we are speaking of the will as an act, we thus distinguish in Christ a will as nature, which is called thelesis , and a will as reason, which is called boulesis .

Reply Obj. 1: These two wills do not diversify the power but only the act, as we have said.

Reply Obj. 2: The intellect and the reason are not distinct powers, as was said in the First Part (Q. 79, A. 8).

Reply Obj. 3: The "will of piety" would not seem to be distinct from the will considered as nature, inasmuch as it shrinks from another's evil, absolutely considered. _______________________

FOURTH ARTICLE [III, Q. 18, Art. 4]

Whether There Was Free-will in Christ?

Objection 1: It would seem that in Christ there was no free-will. For Damascene says (De Fide Orth. iii, 14) that gnome , i.e. opinion, thinking or cogitation, and proairesis , i.e. choice, "cannot possibly be attributed to our Lord, if we wish to speak with propriety." But in the things of faith especially we must speak with propriety. Therefore there was no choice in Christ and consequently no free-will, of which choice is the act.

Obj. 2: Further, the Philosopher says (Ethic. iii, 2) that choice is "a desire of something after taking counsel." Now counsel does not appear to be in Christ, because we do not take counsel concerning such things as we are certain of. But Christ was certain of everything. Hence there was no counsel and consequently no free-will in Christ.

Obj. 3: Further, free-will is indifferent. But Christ's will was determined to good, since He could not sin; as stated above (Q. 15, AA. 1, 2). Hence there was no free-will in Christ.

On the contrary, It is written (Isa. 7:15): "He shall eat butter and honey, that He may know to refuse the evil and to choose the good," which is an act of the free-will. Therefore there was free-will in Christ.

I answer that, As was said above (A. 3), there was a twofold act of the will in Christ; one whereby He was drawn to anything willed in itself, which implies the nature of an end; the other whereby His will was drawn to anything willed on account of its being ordained to another—which pertains to the nature of means. Now, as the Philosopher says (Ethic. iii, 2) choice differs from will in this, that will of itself regards the end, while choice regards the means. And thus simple will is the same as the "will as nature"; but choice is the same as the "will as reason," and is the proper act of free-will, as was said in the First Part (Q. 83, A. 3). Hence, since "will as reason" is placed in Christ, we must also place choice, and consequently free-will, whose act is choice, as was said in the First Part (Q. 83, A. 3; I-II, Q. 13, A. 1).
