He reminds the judges of two popular uprisings and their instigators. One was a certain Theudas, a person not definitely known from history. The other was Judas the Galilean, who stirred up revolt during and because of the census.
This was the census that the Roman emperor Augustus ordered Quirinius, the Syrian governor, to carry out in Judea. Because of it the Nativity of our Lord Jesus Christ took place in Bethlehem (Lk 2:2).
Since the apostles’ work seemed dangerous in the eyes of the Sanhedrin because it was growing more and more (v. 28), Gamaliel reminds them that the mentioned agitators also had success at first. They too drew hundreds of people after themselves.
But, he says, since their work was not the work of God, they themselves perished, and their followers were scattered and vanished.
“And now, I say to you, keep away from these men and leave them alone. For if this plan and this work are from men, it will be overthrown. But if it is from God, you cannot overthrow it. Take care lest you also be found fighters against God.”
The comparison of the apostles with popular agitators seems to show that Gamaliel personally did not hold a high opinion of Christ’s preachers.
Yet the counsel that Gamaliel then gave to the Sanhedrin reflects a favorable view of Christianity. He allows the possibility that the apostles’ work is the work of God. He warns men lest they be found fighters against God.
