Reply Obj. 1: The soul of Christ could have prevented these passions from coming upon it, and especially by the Divine power; yet of His own will He subjected Himself to these corporeal and animal passions.
Reply Obj. 2: Tully is speaking there according to the opinions of the Stoics, who did not give the name of passions to all, but only to the disorderly movements of the sensitive appetite. Now, it is manifest that passions like these were not in Christ.
Reply Obj. 3: The "passions of sins" are movements of the sensitive appetite that tend to unlawful things; and these were not in Christ, as neither was the fomes of sin. _______________________
FIFTH ARTICLE [III, Q. 15, Art. 5]
Whether There Was Sensible Pain in Christ?
Objection 1: It would seem that there was no true sensible pain in Christ. For Hilary says (De Trin. x): "Since with Christ to die was life, what pain may He be supposed to have suffered in the mystery of His death, Who bestows life on such as die for Him?" And further on he says: "The Only-begotten assumed human nature, not ceasing to be God; and although blows struck Him and wounds were inflicted on Him, and scourges fell upon Him, and the cross lifted Him up, yet these wrought in deed the vehemence of the passion, but brought no pain; as a dart piercing the water." Hence there was no true pain in Christ.
Obj. 2: Further, it would seem to be proper to flesh conceived in original sin, to be subject to the necessity of pain. But the flesh of Christ was not conceived in sin, but of the Holy Ghost in the Virgin's womb. Therefore it lay under no necessity of suffering pain.
Obj. 3: Further, the delight of the contemplation of Divine things dulls the sense of pain; hence the martyrs in their passions bore up more bravely by thinking of the Divine love. But Christ's soul was in the perfect enjoyment of contemplating God, Whom He saw in essence, as was said above (Q. 9, A. 2). Therefore He could feel no pain.
On the contrary, It is written (Isa. 53:4): "Surely He hath borne our infirmities and carried our sorrows."
I answer that, As is plain from what has been said in the Second Part (I-II, Q. 35, A. 7), for true bodily pain are required bodily hurt and the sense of hurt. Now Christ's body was able to be hurt, since it was passible and mortal, as above stated (Q. 14, AA. 1, 2); neither was the sense of hurt wanting to it, since Christ's soul possessed perfectly all natural powers. Therefore no one should doubt but that in Christ there was true pain.
