John Chrysostom
"In the name of Jesus Christ of Nazareth." What especially grieved them, the apostle adds. This is precisely what Christ's words meant: "What you hear in the ear, preach on the housetops" (Mt 10:27).
"In the name of Jesus Christ of Nazareth, Whom you crucified, Whom God raised from the dead, by Him this man stands before you whole." Do not think, he says, that we conceal His homeland or His Passion.
"Whom you crucified, Whom God raised from the dead, by Him this man stands before you whole." Again the Passion, again the Resurrection.
But Peter had said, "We did not do this." Mark his prudence. He did not say at once, "We did it in the name of Jesus." How then? "By Him this man stands before you whole." Nor does he say, "He became well through us."

He rebukes them as men who always condemn benefactions. He reminds them of former things, namely, that they seek murders. They not only reveal this, but even accuse others for benefactions.
Do you see how weighty Peter's words are? The apostles had already been trained in this and had finally become fearless.
Here Peter proves to them that they themselves, against their will, preach Christ. By judging and investigating, they themselves spread the teaching concerning Him.
"Whom you crucified." O what boldness! "Whom God raised from the dead." This is a sign of still greater boldness.
His words mean this: Do not think that we conceal anything shameful. No, we not only do not conceal it, but, on the contrary, speak with boldness.
Thus the apostle speaks and almost rebukes them by it. He does not do so merely in passing, but dwells on it, saying, "He is the stone rejected by you builders."
