Jeremiah 28:9

But there are two passages, spoken by Moses himself, which at the first sight seem to militate the one against the other. We have already quoted the first from Deuteronomy 13; we have the other in the Deuteronomy 18:18,

“The prophet who has predicted what is found to be true, I have sent him.”

God seems there to acknowledge as his faithful servants those who foretell what is true. But Moses had before reminded the people that even impostors sometimes speak the truth, but that they ought not on this account to be believed. But we must remember what God often declares by Isaiah, when he claims to himself alone the foreknowledge of things,

“Go,” he says, “and inquire whether the gods of the Gentiles will answer as to future things.” (Isaiah 44:7)

We see that God ascribes to himself alone this peculiarity, that he foreknows future events and testifies respecting them. And surely nothing can be more clear than that God alone can speak of hidden things: men, indeed, can conjecture this or that, but they are often mistaken.

With regard to the devil, I pass by those refined disquisitions with which Augustine especially wearied himself; for above all other things he toiled on this point, how the devils reveal future and hidden things? He speculated, as I have said, in too refined a manner. But the solution of the difficulty, as to the subject now in hand, may be easily given. We first conclude, that future events cannot be known but by God alone, and that, therefore, prescience is his exclusive property, so that nothing that is future or hidden can be predicted but by him alone. But, then, it does not follow that God does not permit liberty to the devil and his ministers to foretell something that is true. How? As the case was with Balaam, who was an impostor, ready to let on hire or to sell his prophecies, as it is well known, and yet he was a prophet. But it was a peculiar gift to foretell things: whence had he this? Not from the devil any farther than it pleased God; and yet the truth had no other fountain than God himself and his Spirit. When, therefore, the devil declares what is true, it is as it were extraneous and adventitious.

Now, as we have said, that God is the source of truth, it follows that the prophets sent by him cannot be mistaken; for they exceed not the limits of their call, and so they do not speak falsely of hidden things; but when they declare this or that, they have him as their teacher. But these terms, as they say, are not convertible — to foretell what is true and to be a true prophet: for some, as I have said, predict what is found afterwards by trial and experience to be true, and yet they are impostors; nor did God, in the eighteenth chapter of Deuteronomy, intend to give a certain definition by which his own prophets are to be distinguished; but as he saw that the Israelites would be too credulous, so as greedily to lay hold on anything that might have been said, he intended to restrain that excess, and to correct that immoderate ardor. Hence he commanded them to expect the event, as though he had said, “If any arise among you who will promise this or that in my name, do not immediately receive what they may announce; but the event will shew whether I have sent them.” So also, in this place, Jeremiah says, that the true prophets of God had spoken efficiently, as they had predicted nothing but what God had ratified and really proved to have come from him.

Thus, then, we ought to think of most, that is, that those who predict what is true are for the most part the prophets of God: this is to be taken as the general rule. But we cannot hence conclude, that all those who apparently predict this or that, are sent by God, so that the whole of what they teach is true: for one particular prophecy would not be sufficient to prove the truth of all that is taught and preached. It is enough that God condemns their vanity who speak from their own hearts or from their own brains, when the event does not correspond. At the same time he points out his own prophets by this evidence, — that he really shews that he has sent them, when he fulfils what has been predicted by them. As to false prophets there is a special reason why God permits to them so much liberty, for the world is worthy of such reward, when it willingly offers itself to be deceived. Satan, the father of lies, lays everywhere his snares for men, and they who run into them, and wish to cast themselves on his tenterhooks, deserve to be given up to believe a lie, as they will not, as Paul says, believe the truth. (2 Thessalonians 2:10, 11.)

We now then see what was the object of Jeremiah: his design was not to prove that all were true prophets who predicted something that was true, for this was not, his subject; but he took up another point, — that all who predicted this or that, which was afterwards found to be vain, were thus convicted of falsehood. If then any one predicted what was to be, and the thing itself came not to pass, it was a sufficient proof of his presumption: it hence appeared, that he was not sent of God as he boasted. This was the object of Jeremiah, nor did he go beyond it; for he did not discuss the point, whether all who predicted true things were sent from above, and whether all their doctrines were to be credited and they believed indiscriminately; this was not the subject handled by Jeremiah; but he shewed that Hananiah was a false prophet, for it would appear evident after two years that he had vainly spoken of what he had not received from God’s Spirit. And the same thing Moses had in view, as I have already explained.

As to the prophets, who had been in all ages and prophesied respecting many lands and great kingdoms, they must be considered as exclusively the true prophets: for though there had been some prophets among heathen nations, yet Jeremiah would not have thought them worthy of so great an honor; and it would have been to blend together sacred and profane things, had he placed these vain foretellers and the true prophets in the same rank. But we know that all God’s servants had so directed their discourse to the elect people, as yet to speak of foreign kingdoms and of far countries; and this has not been without reason distinctly expressed; for when they spoke of any monarchy they could not of themselves conjecture what would be: it was therefore necessary for them thus to speak by the impulse of the Holy Spirit. Were I disposed to assume more than what is lawful, and to pretend that I possess some special gift of prophesying, I could more easily lie and deceive, were I to speak only of one city, and of the state of things open before my eyes, than if I extended my predictions to distant countries: when therefore Jeremiah says that the prophets had spoken of divers and large countries, and of most powerful kingdoms, he intimates that their predictions could not have been ascribed to human conjectures; for were any one possessed of the greatest acuteness, and were he to surpass angels in intelligence, he yet could not predict what is hereafter to take place in lands beyond the seas But whatever had been predicted by the prophets, God sanctioned it by the events of time. It then follows that their call was at the same time sanctioned; that is, when God as it were ratified from heaven what they had spoken on earth. Whether therefore the prophets spoke of peace, that is, of prosperity, or of war, famine, and pestilence, when experience proved that true which they had said, their own authority was at the same time confirmed, as though God had shewed that they had been sent by him.

We must also notice the word באמת, beamet, he says that God sent them in truth He condemns here the boldness which impostors ever assume; for they surpass God’s faithful servants in boasting that they have been sent. As then they were thus insolent, and by a fallacious pretense of having been called to their office, deceived unwary men, the Prophet adds here this clause, intimating that they were not all sent in truth. He thus conceded some sort of a call to these unprincipled men, but yet shewed how much they differed from God’s servants, whose call was sealed by God himself. It follows —
