Bede : And they could not withstand the wisdom and the Spirit with which he spoke. This is what the Lord Himself says to His martyrs: For I will give you words and wisdom that none of your adversaries will be able to resist or contradict. It was fitting that in the first martyr, what He deigned to promise to all who are betrayed for His name should be confirmed. — Commentary on Acts Bede : And they were not able to resist the wisdom and the Holy Spirit who spoke. In the Greek text, there is more: "And they were not able to resist the wisdom that was in him, and the Holy Spirit who spoke: for which reason they were reproved by him with all confidence." Therefore, when they could not contradict the truth, then they suborned men who said, etc. — Retractions on Acts John Chrysostom : "Disputing with Stephen." Observe him, not taking upon him to teach, but forced to do so. The miracles once more brought him into ill-will; but when he overcame in argument, it was false-witness! For they did not wish to kill intolerable to them. "They could not resist, etc.: then they suborned men." Everywhere out of hand, but by means of a sentence, that they might hurt their reputation also: and leaving those (the Apostles), they attack these (the disciples), thinking in this way to terrify those also. — Homily on Acts 15 John Chrysostom : Observe the power of the preaching, that, though they are not only scourged but stoned, it still prevails: not only, private individuals as they are, dragged to the bar, but assailed from all quarters: and, their enemies themselves being witnesses, not only were these worsted, but "they were not able" even "to resist," though they were exceeding shameless: so mightily did it overthrow them, for all that they could do with their preposterous figments (as the saying that He had a devil - He that cast out devils!). For the battle was not man's, but God's against men. And there were many combined together; not only they in Jerusalem, but others as well. — Homily on Acts 15
