John 7:31

"When Christ cometh, will He do more miracles than these which this man hath done?" How many were the miracles? In truth, there were three, that of the wine, that of the paralytic, and that of the nobleman's son; and the Evangelist hath related no more. From which circumstance it is plain, as I have often said, that the writers pass by most of them, and discourse to us of those alone on account of which the rulers ill-treated Him. "Then they sought to take Him," and kill Him. Who "sought"? Not the multitude, who had no desire of rule, nor could be made captives by malice; but the priests. For they of the multitude said, "When Christ cometh, will He do more miracles?" Yet neither was this sound faith, but, as it were, the idea of a promiscuous crowd; for to say, "When He cometh," was not the expression of men firmly persuaded that He was the Christ. We may either understand the words thus, or that they were uttered by the multitudes when they came together. "Since," they may have said, "our rulers are taking every pains to prove that this man is not the Christ, let us suppose that he is not the Christ; will the Christ be better than he?" For, as I ever repeat, men of the grosser sort are led in not by doctrine, nor by preaching, but by miracles.

"The Pharisees heard the people murmuring, and sent servants to take Him." Seest thou that the violation of the Sabbath was a mere pretense? and that what most stung them was this murmuring? For here, though they had no fault to find with Him for anything said or done, they desired to take Him because of the multitude. They dared not do it themselves, suspecting danger, but sent their hired servants. Alas! for their tyranny and their madness, or rather, I should say, for their folly. After having often attempted themselves, and not prevailed, they committed the matter to servants, simply satisfying their anger.

"But many of the people believed on Him." The Lord made whole the humble and the poor. The rulers were mad, and therefore they not only did not acknowledge the Physician, but even were eager to slay Him. There was a certain crowd of people which quickly saw its own sickness, and without delay recognized His remedy. See what that very crowd, moved by His miracles, said: "When Christ cometh will He do more signs than these?" Surely, unless there will be two Christs, this is the Christ. Consequently, in saying these things, they believed on Him.

(Tract. xxxi. 7) And many of the people believed on Him. Our Lord brought the poor and humble to be saved. The common people, who soon saw their own infirmities, received His medicine without hesitation.
