“Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled and they took knowledge of them, that they had been with Jesus.” The two unlearned men beat down with their rhetoric them and the chief priests. For it was not they that spoke, but the grace of the Spirit. “And beholding the man which was healed standing with them, they could say nothing against it.” Great was the boldness of the man; that even in the judgment-hall he has not left them. For had they said that the fact was not so, there was he to refute them. “But when they had commanded them to go aside out of the council, they conferred among themselves, saying, What are we to do to these men?” See the difficulty they are in, and how the fear of men again does everything. As in the case of Christ, they were not able (as the saying is) to undo what is done, nor to cast it into the shade, but for all their hindering, the Faith did but gain ground the more; so was it now. “What shall we do?” O the folly! To suppose that those who had tasted of the conflict, would now take fright at it: to expect, impotent as their efforts had proved in the beginning, to effect something new, after such a specimen of oratory as had been exhibited! The more they wished to hinder, the more the business grew upon their hands. But what say they? “For that indeed a notable miracle has been done by them is manifest to all them that dwell in Jerusalem; and we cannot deny it. But that it spread no further among the people, let us straightly threaten them, that they speak henceforth to no man in this name. And they called them, and commanded them not to speak at all, nor teach, in the name of Jesus.” See what effrontery is shown by these, and what greatness of mind by the Apostles. “But Peter and John answered and said unto them, Whether it be right in the sight of God to hearken unto you more than unto God, judge ye. For we cannot but speak the things which we have seen and heard. So when they had further threatened them, they let them go, finding nothing how they might punish them, because of the people.” The miracles shut their mouths: they would not so much as let them finish their speech, but cut them short in the middle, most insolently. “For all men glorified God for that which was done. For the man was above forty years old, on whom this miracle of healing was showed.” But let us look over what has been said from the beginning.
“And as they spoke unto the people, etc. Being grieved that they taught the people, and preached through Jesus the resurrection of the dead.” (Recapitulation, <!--<span class="stiki"></span>-->v. 1, 2.) So then at first they did all for the sake of man's opinion (or glory): but now another motive was added: that they should not be thought guilty of murder, as they said subsequently, “Do ye wish to bring this man's blood on us?” O the folly! Persuaded that He was risen, and having received this proof of it, they expected that He Whom death could not hold, could be cast into the shade by their machinations! What can match the folly of this! Such is the nature of wickedness: it has no eyes for anything, but on all occasions it is thrown into perturbation. Finding themselves overborne, they felt like persons who have been outwitted: as is the case with people who have been forestalled and made a sport of in some matter. And yet they everywhere affirmed that it was God that raised Him: but it was “in the Name of Jesus” that they spoke; showing that Jesus was risen. “Through Jesus, the resurrection of the dead”: for they themselves also held a resurrection: a cold and puerile doctrine, indeed, but still they held it. Why this alone, was it not sufficient to induce them to do nothing to them— I mean, that the disciples with such boldness bore themselves in the way they did? Say, wherefore, O Jew, do you disbelieve? You ought to have attended to the sign done, and to the words, not to the evil disposition of the many. “By their teaching the people.” For already they were in ill repute with them by reason of what they had done to Christ; so that they were rather increasing their own obloquy. “And they laid hands on them, and put them in hold until the morrow; for it was now eventide.” In the case of Christ, however, they did not so; but having taken Him at midnight, they immediately led him away, and made no delay, being exceedingly in fear of the multitude: whereas in the case of the Apostles here, they were bold. And they no more take them to Pilate, being ashamed and blushing at the thought of the former affair, lest they should also be taken to task for that.
