Reply Obj. 1: By His rational will Christ willed the Divine will to be fulfilled; but not by His will of sensuality, the movement of which does not extend to the will of God—nor by His will considered as nature which regards things absolutely considered and not in relation to the Divine will.
Reply Obj. 2: The conformity of the human will to the Divine regards the will of reason: according to which the wills even of friends agree, inasmuch as reason considers something willed in its relation to the will of a friend.
Reply Obj. 3: Christ was at once comprehensor and wayfarer, inasmuch as He was enjoying God in His mind and had a passible body. Hence things repugnant to His natural will and to His sensitive appetite could happen to Him in His passible flesh. _______________________
SIXTH ARTICLE [III, Q. 18, Art. 6]
Whether There Was Contrariety of Wills in Christ?
Objection 1: It would seem that there was contrariety of wills in Christ. For contrariety of wills regards contrariety of objects, as contrariety of movements springs from contrariety of termini, as is plain from the Philosopher (Phys. v, text. 49, seq.). Now Christ in His different wills wished contrary things. For in His Divine will He wished for death, from which He shrank in His human will, hence Athanasius says [*De Incarnat. et Cont. Arianos, written against Apollinarius]: "When Christ says 'Father, if it be possible, let this chalice pass from Me; yet not My will, but Thine be done,' and again, 'The spirit indeed is willing, but the flesh weak,' He denotes two wills—the human, which through the weakness of the flesh shrank from the passion—and His Divine will eager for the passion." Hence there was contrariety of wills in Christ.
Obj. 2: Further, it is written (Gal. 5:17) that "the flesh lusteth against the spirit, and the spirit against the flesh." Now when the spirit desires one thing, and the flesh another, there is contrariety of wills. But this was in Christ; for by the will of charity which the Holy Spirit was causing in His mind, He willed the passion, according to Isa. 53:7: "He was offered because it was His own will," yet in His flesh He shrank from the passion. Therefore there was contrariety of wills in Him.
Obj. 3: Further, it is written (Luke 22:43) that "being in an agony,
He prayed the longer." Now agony seems to imply a certain struggle
[*Greek, agonia] in a soul drawn to contrary things. Hence it seems
that there was contrariety of will in Christ.
On the contrary, In the decisions of the Sixth Council [*Third Council of Constantinople, Act. 18] it is said: "We confess two natural wills, not in opposition, as evil-minded heretics assert, but following His human will, and neither withstanding nor striving against, but rather being subject to, His Divine and omnipotent will."
I answer that, Contrariety can exist only where there is opposition in the same and as regards the same. For if the diversity exists as regards diverse things, and in diverse subjects, this would not suffice for the nature of contrariety, nor even for the nature of contradiction, e.g. if a man were well formed or healthy as regards his hand, but not as regards his foot. Hence for there to be contrariety of wills in anyone it is necessary, first, that the diversity of wills should regard the same. For if the will of one regards the doing of something with reference to some universal reason, and the will of another regards the not doing the same with reference to some particular reason, there is not complete contrariety of will, e.g. when a judge wishes a brigand to be hanged for the good of the commonwealth, and one of the latter's kindred wishes him not to be hanged on account of a private love, there is no contrariety of wills; unless, indeed, the desire of the private good went so far as to wish to hinder the public good for the private good—in that case the opposition of wills would regard the same.
