Matthew 27:25

25.His blood be on us. There can be no doubt that the Jews pronounced this curse on themselves without any concern, as if they had been fully convinced that they had a righteous cause before God; but their inconsiderate zeal carries them headlong, so that, while they commit an irreparable crime, they add to it a solemn imprecation, by which they cut themselves off from the hope of pardon. Hence we infer how carefully we ought to guard against headlong rashness in all our judgments. For when men refuse to make inquiry, and venture to decide in this or the other matter according to their own fancy, blind impulse must at length carry them to rage. And this is the righteous vengeance of God with which he visits the pride of those who do not deign to take the trouble of distinguishing between right and wrong. The Jews thought that, in slaying Christ, they were performing a service acceptable to God; but whence arose this wicked error, unless from wicked obstinacy, and from despising God himself? Justly, therefore, were they abandoned to this rashness of drawing upon themselves final ruin. But when the question relates to the worship of God and his holy mysteries, let us learn to open our eyes, and to inquire into the matter with reverence and sobriety, lest through hypocrisy and presumption we become stupefied and enraged.

Now as God would never have permitted this execrable word to proceed from the mouth of the people, if their impiety had not been already desperate, so afterwards he justly revenged it by dreadful and unusual methods; and yet by an incredible miracle he reserved for himself some remnant, that his covenant might not be abolished by the destruction of the whole nation. He had adopted for himself the seed of Abraham, that it might be

a chosen nation, a royal priesthood, his peculiar people and inheritance,
(1 Peter 2:9.)

The Jews now conspire, as with one voice, to renounce a favor so distinguished. Who would not say that the whole nation was utterly rooted out from the kingdom of God? But God, through their treachery, renders more illustrious the fidelity of his promise, and, to show that he did not in vain make a covenant with Abraham, he rescues from the general destruction those whom he has elected by free grace. Thus the truth of God always rises superior to all the obstacles raised by human unbelief.
