John Calvin's Bible Commentary
Jeremiah 28:10
It was not enough for the impostor to resist the holy servant of God to his face, without laying sacrilegious hands on that visible symbol, by which it had pleased God to testify that the Prophet’s message was true. For such was the tardiness of the people, nay, their insensibility, that they could not be much moved by words; therefore God added a symbol, for Jeremiah carried cords or bands around his neck: and it was a sign of reproach before men, yet, in order to touch the people, he refused not to undergo that reproach.
The band then on the neck of Jeremiah was like a sacrament; for it was a visible sign to establish the credit of his message. And what did Hananiah do? After having insolently inveighed against Jeremiah, and promised deliverance to the people after two years, he violently broke and took off the cord or the band which Jeremiah had around his neck.
We hence see how great and how impetuous is the fury of those whom the devil impels: for when once they arrive at that degree of temerity as to dare to resist the word of God, and, were it possible, to cast him from his own throne, they spare no symbols of his power and glory. We ought especially to notice this madness of Hananiah; for he not only resisted God’s servant, and endeavored to subvert his prophecy, but also snatched away the bands, that he might set up the falsehood of the devil in opposition to the true sacrament. This sign, as we have said, availed to confirm the prophecy of which we have heard; but what was done by Hananiah? he not only took away that sign, but by breaking the bands he attracted the attention of men, and by such a representation made them to believe that there would be in two years a deliverance. Then Hananiah displayed his furious zeal in two ways; for he profaned that symbol which Jeremiah had adopted according to God’s command, and he also took it away, as though he aimed to be above God, and to overthrow his truth, and would triumph over it.
The same thing we now see done under the Papacy: for we know that what Christ had commanded has been either corrupted, or obscured, or blotted out by them; and they have also devised fictitious sacraments and innumerable pompous rites, by which they fascinate foolish and credulous men. The same did Hananiah; and therefore his disciples and imitators are the Papists; who not only reject or extenuate the testimonies which have come from God, but plainly dishonor his sacraments by arrogantly bringing forward their own devices and inventions.
