John Chrysostom

This Gamaliel was Paul's teacher. And one may well wonder, how, being so right-minded in his judgment, and withal learned in the law, he did not yet believe. But it cannot be that he should have continued in unbelief to the end. Indeed it appears plainly from the words he here speaks. He "commanded," it says, "to put the men forth a little space and said unto them." Observe how judiciously he frames his speech, and how he immediately at the very outset puts them in fear. …

Theophylact of Ohrid

As for Gamaliel, he was the teacher of Paul; and it is worthy of wonder how he, being a teacher of the law and a man of discerning mind, had not yet believed up to this point. This is because Paul had not yet believed either. Pay attention to the wise adaptability of the speech — to how Gamaliel immediately struck them with fear, and so as not to give the suspicion that he shared the views of the apostles, he converses with the Jews as with people of the same convictions and does not express himself particularly harshly, but says: …

Bede

Then stood up one in the council, a Pharisee named Gamaliel, a doctor of the law, etc. Of this Gamaliel, we read in the book of Saint Clement, that he was secretly a disciple of the apostles, but by their counsel, he was commanded to remain among the Jews to mitigate their fury where necessity required; but this has been most certainly made known today as a true account through the revelation of the relics of the most blessed protomartyr Stephen, which was made widely known to the Church of Christ through the divine dispensation by …

Cassiodorus

"But one in the council rising up, a Pharisee, named Gamaliel, a doctor of the law, said. "Gamaliel, whom the apostle Paul also praises, spoke publicly to persuade them that they should desist from persecuting the apostles, saying: "If their preaching be from men, it will undoubtedly fail, as did that of Theodas and of Judas of Galilee; if, on the other hand, it be from God, it cannot possibly be destroyed by any power." Then they scourged the apostles and let them go, charging them that they should no longer be involved in such …
