John Chrysostom

So there was a division among the people concerning Him. (Hom. li. 2) The Evangelist says this to show, that they had no concern for, and no anxiety to learn, the truth.

Catena Aurea by Aquinas ↗

Cyril of Alexandria

To no purpose do they wrangle and are split into diverse opinions, some supposing that He is the Prophet, others the Christ. And the cause of their division, that they know not Christ, nor understand the accuracy of the Holy Scriptures: for else would they believing that none other is Jesus than the Prophet of the Law, have departed from their unseasonable dispute.

Theophylact of Ohrid

The division arose among the people, not among the rulers, because the rulers held to one opinion: not to accept Him as the Christ.

Thomas Aquinas

Then the disagreement among the people is mentioned. And so there was dissension among the people because of him, that is, Christ. For it often happens that when the truth is made known, it causes dissensions and uneasiness in the hearts of the wicked. So Jeremiah says, representing Christ: "Woe is me, my mother! Why did you give birth to me as a man of strife and dissension for all the earth" (Jer 15:10). And our Lord said: "I have not come to send peace, but the sword" (Mt 10:34).

Bonaventure

"There arose therefore a division among the crowd on account of him." He himself was not the cause, but their malice was. Chrysostom: "They were divided, not moved to compunction, for malice is willing to yield to no one." On account of this division, some wished to seize him as an evildoer, while others wished to release him as a good man; and from this contention the machination of the Pharisees was frustrated, because the officers did not extend their hands to seize him, although some wished to do so.
