Whether it was fitting for Christ to suffer at the hands of the Gentiles?

Objections

Objection 1 : It would seem unfitting that Christ should suffer at the hands of the Gentiles. For since men were to be freed from sin by Christ's death, it would seem fitting that very few should sin in His death. But the Jews sinned in His death, on whose behalf it is said (Mt. 21:38): "This is the heir; come, let us kill him." It seems fitting, therefore, that the Gentiles should not be implicated in the sin of Christ's slaying.
Objection 2 : Further, the truth should respond to the figure. Now it was not the Gentiles but the Jews who offered the figurative sacrifices of the Old Law. Therefore neither ought Christ's Passion, which was a true sacrifice, to be fulfilled at the hands of the Gentiles.
Objection 3 : Further, as related Jn. 5:18, "the Jews sought to kill" Christ because "He did not only break the sabbath, but also said God was His Father, making Himself equal to God." But these things seemed to be only against the Law of the Jews: hence they themselves said (Jn. 19:7): "According to the Law He ought to die because He made Himself the Son of God." It seems fitting, therefore, that Christ should suffer, at the hands not of the Gentiles, but of the Jews, and that what they said was untrue: "It is not lawful for us to put any man to death," since many sins are punishable with death according to the Law, as is evident from Lev. 20.
