Reply Obj. 1: Those words are spoken by the husbandmen of the vineyard; and these signify the rulers of the people, who knew Him to be the heir, inasmuch as they knew Him to be the Christ promised in the Law, but the words of Ps. 2:8 seem to militate against this answer: "Ask of Me, and I will give Thee the Gentiles for Thy inheritance"; which are addressed to Him of whom it is said: "Thou art My Son, this day have I begotten Thee." If, then, they knew Him to be the one to whom the words were addressed: "Ask of Me, and I will give Thee the Gentiles for Thy inheritance," it follows that they knew Him to be the Son of God. Chrysostom, too, says upon the same passage that "they knew Him to be the Son of God." Bede likewise, commenting on the words, "For they know not what they do" (Luke 23:34), says: "It is to be observed that He does not pray for them who, understanding Him to be the Son of God, preferred to crucify Him rather than acknowledge Him." But to this it may be replied that they knew Him to be the Son of God, not from His Nature, but from the excellence of His singular grace.
Yet we may hold that they are said to have known also that He was verily the Son of God, in that they had evident signs thereof: yet out of hatred and envy, they refused credence to these signs, by which they might have known that He was the Son of God.
Reply Obj. 2: The words quoted are preceded by the following: "If I had not done among them the works that no other man hath done, they would not have sin"; and then follow the words: "But now they have both seen and hated both Me and My Father." Now all this shows that while they beheld Christ's marvelous works, it was owing to their hatred that they did not know Him to be the Son of God.
Reply Obj. 3: Affected ignorance does not excuse from guilt, but seems, rather, to aggravate it: for it shows that a man is so strongly attached to sin that he wishes to incur ignorance lest he avoid sinning. The Jews therefore sinned, as crucifiers not only of the Man-Christ, but also as of God. _______________________
SIXTH ARTICLE [III, Q. 47, Art. 6]
Whether the Sin of Those Who Crucified Christ Was Most Grievous?
Objection 1: It would seem that the sin of Christ's crucifiers was not the most grievous. Because the sin which has some excuse cannot be most grievous. But our Lord Himself excused the sin of His crucifiers when He said: "Father, forgive them: for they know not what they do" (Luke 23:34). Therefore theirs was not the most grievous sin.
Obj. 2: Further, our Lord said to Pilate (John 19:11): "He that hath delivered Me to thee hath the greater sin." But it was Pilate who caused Christ to be crucified by his minions. Therefore the sin of Judas the traitor seems to be greater than that of those who crucified Him.
Obj. 3: Further, according to the Philosopher (Ethic. v): "No one suffers injustice willingly"; and in the same place he adds: "Where no one suffers injustice, nobody works injustice." Consequently nobody wreaks injustice upon a willing subject. But Christ suffered willingly, as was shown above (AA. 1, 2). Therefore those who crucified Christ did Him no injustice; and hence their sin was not the most grievous.
On the contrary, Chrysostom, commenting on the words, "Fill ye up, then, the measure of your fathers" (Matt. 23:32), says: "In very truth they exceeded the measure of their fathers; for these latter slew men, but they crucified God."
