Jeremiah 23:30

Jeremiah returns again to the false teachers, who were the authors of all the evils; for they fascinated the people with their flatteries, so that every regard for sound and heavenly doctrine was almost extinguished. But while God declares that he is an avenger against them, he does not exempt the people from punishment. We indeed know that a just reward was rendered to the reprobate, when God let loose the reins to the ministers of Satan with impunity to deceive them. But as the people acquiesced in those false allurements, while Jeremiah so severely reproved the false teachers, he reminds the people how foolishly they betook themselves under the shadow of those men, thinking themselves to be safe.

He says, first, Behold, I am, against the prophets, who steal my words every one from his neighbor. Many explain this verse as though God condemned the false prophets, who borrowed something from the true prophets, so that they might be their rivals and as it were their apes; and no doubt the ungodly teachers had ever from the beginning made some assumptions, that they might be deemed God’s servants. But it seems, however, a forced view, that they stole words from the true prophets, for the words express what is different, that they stole every one from his friend Jeremiah would not have called God’s faithful servants by this name. I rather think that their secret arts are here pointed out, that they secretly and designedly conspired among themselves, and then that they spread abroad their own figments according to their usual manner. For the ungodly and the perfidious, that they might obtain credit among the simple and unwary, consulted together and devised all their measures craftily, that they might not be immediately found out; and thus one took from the other what he afterwards announced and published. And this is what Jeremiah calls stealing, because they secretly consulted, and then declared to the people what they agreed upon among themselves; and they did this as though every one had derived his oracle from heaven. I have, therefore, no doubt but that the Prophet condemns these hidden consultations when he says that every one stole from his neighhour. (113)

We indeed see the same thing now under the Papacy, for the monks and unprincipled men of the same character have their own false doctrines; and when they ascend the pulpit, every one speaks as though he was endued with some special gift; and yet they steal every one from his friend, for they are like the soothsayers or the magi, who concocted among themselves their own falsehoods, and only brought out what they deemed necessary to delude the common people. This, then, was one of the vices which the Prophet shews prevailed among the false teachers, — that no one attended to the voice of God, but that every one took furtively from his friend what he afterwards openly proclaimed.
