And now, brethren, I know that you did it through ignorance, as did also your rulers.

“And it were the exercise of no ordinary arbitrariness, for those who had departed before the advent of the Lord (not having the Gospel preached to them, and having afforded no ground from themselves, in consequence of believing or not) to obtain either salvation or punishment. For it is not right that these should be condemned without trial, and that those alone who lived after the advent should have the advantage of the divine righteousness. But to all rational souls it was said from above, "Whatever one of you has done in ignorance, without clearly knowing God, if, on becoming conscious, he repent, all his sins will be forgiven him." "For, behold," it is said, "I have set before your face death and life, that ye may choose life." God says that He set, not that He made both, in order to the comparison of choice.”

“Then, when their minds were alarmed, immediately he encourages them, by the appellation of Brethren, "And now, brethren, I wot, etc." For in the former discourse he foretold nothing, but only says concerning Christ, "Therefore let all the house of Israel know assuredly:" here he adds an admonition. There he waited till the people spoke: here, he knew how much they had already effected, and that the present assembly was better disposed toward them. "That through ignorance ye did it." And yet the circumstances mentioned above were not to be put to the score of ignorance. To choose the robber, to reject Him Who had been adjudged to be acquitted, to desire even to destroy Him-how should this be referred to ignorance? Nevertheless, he gives them liberty to deny it, and to change their mind about what had happened. "And now, brethren, I wot that through ignorance ye did it, as did also your rulers." This is one ground of excuse. The second is of a different kind. As Joseph speaks to his brethren, "God did send me before you"; what in the former speech he had briefly said, in the words, "Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken,"-this he here enlarges upon: "But what God before had showed by the mouth of all His Prophets, that His Christ should suffer, He hath so fulfilled." At the same time showing, that it was not of their doing, if this be proved, that it took place after God's counsel. "Now this indeed, that you put to death the innocent, ye knew: but that you were killing 'the Prince of Life,' this, belike, ye did not know." And he exculpated not them alone, but also the chief contrivers of the evil, "ye and your rulers:" for doubtless it would have roused their opposition, had he gone off into accusation. For the evil-doer, when you accuse him of some wickedness that he has done, in his endeavor to exonerate himself, grows more vehement. And he no longer says, "Ye crucified," "Ye killed," but, "Ye did it;" leading them to seek for pardon. There is one extenuating circumstance: they did it in ignorance. This fact forms the transition-point to the presentation of a different side of the death of Jesus. It was their crime, but it was also God's plan. They did it from motives of blindness and hate, but God designed it for their salvation. So that Peter, in effect, says: There is hope for you although you have slain the Lord, for his sacrificial death is the ground of salvation. To this view of the death of Christ he now appeals as basis of hope and a motive to repentance.”

“And see that the true doctor does not become angry with the insane assaulting him, but rather pities them and wishes to heal the raging ones from what he suffers. Listen to the doctor hanging on the cross; surrounded by a crowd of raging madmen, he says: Father, forgive them, for they do not know what they are doing. And his voice was not in vain. For after he rose again and was glorified in the eyes of his disciples, so much so that he showed them the scars of the same resurrected flesh, not only presenting himself to be seen but also to be touched, he ascended into heaven, sent the Holy Spirit: miracles began to occur in the name of the one killed, in the name of the crucified, and those who killed him were more deeply pierced than when they saw him hanging on the cross. For they thought that such things happened in the name of the one who was believed to have been killed by their hands. They felt the living one, whom they had mocked as he was dying. They were pierced in heart, as it is written in the Acts of the Apostles; many of the Jews who crucified the Lord sought counsel from the apostles; they also received counsel, because that hanging one did not say in vain: Father, forgive them, for they do not know what they are doing. The apostle said to them: Repent, and be baptized every one of you in the name of our Lord Jesus Christ, and your sins will be forgiven you. It happened: they were baptized and believed in the one whom they crucified.”

“And now, brethren,.... He calls them brethren, because they were so according to the flesh; and to testify his cordial love and affection for them. I wot, or "I know", that through ignorance ye did it; delivered up Jesus into the hands of Pilate; denied him to be the Messiah before him; preferred a murderer to him, and put him to death. As did also your rulers; the members of the sanhedrim, some of them; see Co1 2:8 for others of them knew him to be the Messiah, to be sent of God, by the miracles he did, and yet blasphemously ascribed them to Satan; and so sinning against light and knowledge, in such a malicious manner, sinned the sin against the Holy Ghost, to which ignorance is here opposed; and which did not excuse from sin: nor was it itself without sin; nor is it opposed to any sin, but to this now mentioned.”

“I wot - Οιδα, I know. Wot is from the Anglo-Saxon, to know; and hence wit, science or understanding. Through ignorance ye did it - This is a very tender excuse for them; and one which seems to be necessary, in order to show them that their state was not utterly desperate; for if all that they did to Christ had been through absolute malice, (they well knowing who he was), if any sin could be supposed to be unpardonable, it must have been theirs. Peter, foreseeing that they might be tempted thus to think, and consequently to despair of salvation, tells them that their offense was extenuated by their ignorance of the person they had tormented and crucified. And one must suppose that, had they been fully convinced that this Jesus was the only Messiah, they never would have crucified him; but they did not permit themselves to receive conviction on the subject.”
