John Chrysostom

"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 spake, but the grace of the Spirit.

Behold another miracle not less than the former. "And beholding the boldness of Peter and John," etc. "And they took knowledge of them that they had been with Jesus." Not without a meaning has the Evangelist set down this passage; but in saying, "they recognized them that they had been with Jesus," he means, in His Passion: for only these were with Him at that time, and then indeed they had seen them humble, dejected: and this it was that most surprised them: the greatness of the change. For in fact Annas and Caiaphas with their company were there, and these then also had stood by Him, and their boldness now amazed them. "And beholding the boldness." For not only their words; their very bearing showed it; that they should stand there so intrepidly to be tried in a cause like this, and with uttermost peril impending over them! Not only by their words, but by their gesture also, and their look and voice, and, in short, by everything about them, they manifested the boldness with which they confronted the people. From the things they uttered, they marvelled, perhaps: "that they were unlearned and common men:" for one may be unlearned, yet not a common or private man, and a common man, yet not unlearned. "Having perceived," it says. Whence? From what they said? Peter does not draw out long speeches, but then by his very manner and method he declares his confidence. "And they recognized them that they had been with Jesus." Which circumstance made them believe that it was from Him they had learned these things, and that they did all in the character of His disciples.
