John Chrysostom

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.
