“ But the sin of all these was greater than that of Pilate, who slew Christ from fear of Caesar; and even greater than the sin of the soldiers who crucified Him at the governor's bidding, not out of cupidity like Judas, nor from envy and hate like the chief priests.
Reply to Objection 3: Christ, indeed willed His Passion just as the Father willed it; yet He did not will the unjust action of the Jews. Consequently Christ's slayers are not excused of their injustice. Nevertheless, whoever slays a man not only does a wrong to the one slain, but likewise to God and to the State ”

“ Further, a man is said to do from obedience what he does from necessity of precept. But Christ did not suffer necessarily, but voluntarily. Therefore He did not suffer out of obedience.
Objection 3: Further, charity is a more excellent virtue than obedience. But we read that Christ suffered out of charity, according to Eph. 5:2: "Walk in love, as Christ also has loved us, and delivered Himself up for us." Therefore Christ's Passion ought to be ascribed rather to charity than to obedience.
On the contrary, It is written (Phil. 2:8) : "He became obedient" to the Father "unto death." ”

“ In another way someone causes an effect indirectly---that is, by not preventing it when he can do so; just as one person is said to drench another by not closing the window through which the shower is entering: and in this way Christ was the cause of His own Passion and death. For He could have prevented His Passion and death. ”

“ Thirdly, by not shielding Him from the Passion, but abandoning Him to His persecutors: thus we read (Mat. 27:46) that Christ, while hanging upon the cross, cried out: "My God, My God, why hast Thou forsaken Me?" because, to wit, He left Him to the power of His persecutors, as Augustine says (Ep. cxl) .
Reply to Objection 1: It is indeed a wicked and cruel act to hand over an innocent man to torment and to death against his will. Yet God the Father did not so deliver up Christ, but inspired Him with the will to suffer for us. ”

“ Christ received a command from the Father to suffer. For it is written (Jn. 10:18) : "I have power to lay down My life, and I have power to take it up again: (and) this commandment have I received of My Father"---namely, of laying down His life and of resuming it again. ”

“ On the contrary, It is written (Lk. 18:33) : "After they have scourged Him, they will put him to death."
I answer that, A thing may cause an effect in two ways: in the first instance by acting directly so as to produce the effect; and in this manner Christ's persecutors slew Him because they inflicted on Him what was a sufficient cause of death, and with the intention of slaying Him, and the effect followed, since death resulted from that cause. ”

“ He "took not away," suffering Himself to be fastened to a tree on account of the apple which man had plucked from the tree against God's command.
Reply to Objection 2: Although obedience implies necessity with regard to the thing commanded, nevertheless it implies free-will with regard to the fulfilling of the precept. And, indeed, such was Christ's obedience, for, although His Passion and death, considered in themselves, were repugnant to the natural will, yet Christ resolved to fulfill God's will with respect to the same, according to Ps. ”
