Since, then, Christ was announced by the Creator, "who formeth the lightning, and createth the wind, and declareth unto man His Christ," as the prophet Joel says, since the entire hope of the Jews, not to say of the Gentiles too, was fixed on the manifestation of Christ,-it was demonstrated that they, by their being deprived of those powers of knowledge and understanding-wisdom and prudence, would fail to know and understand that which was predicted, even Christ; when the chief of their wise men should be in error respecting Him-that is to say, their scribes and prudent ones, or Pharisees; and when the people, like them, should hear with their ears and not understand Christ while teaching them, and see with their eyes and not perceive Christ, although giving them signs.
And besides, the sequel is enough to bear him out on this point: so now the discourse is for all in common. "But this is that which was spoken by the prophet Joel, And it shall come to pass in the last days, saith the Lord God." Nowhere as yet the name of Christ, nor His promises but the promise is that of the Father. Observe the wisdom: observe the considerate forbearance. He did not pass on to speak at once of the things relating to Christ; that He had promised this after His Crucifixion; truly that would have been to upset all. And yet, you will say, here was sufficient to prove His divinity. True, it was, if believed (and the very point was that it should be believed); but if not believed, it would have caused them to be stoned.
And he added nothing, but, "This," says he, "is that which was spoken by the prophet Joel; And it shall come to pass in the last days." He shows, in fact, that the consummation is nigh at hand, and the words, "In the last days," have a kind of emphasis.
For Peter says, "It is the third hour of the day." And what of that? Is it not at the third hour that one becomes drunk? Certainly, that was not in accordance with their intention: for they did not truly think that of them, but said it while jeering and mocking. He made them formerly more careful; but these things happened at the third hour, not simply. For then the brilliance of the fire is shown, when men are neither at work nor at their meal, when the day is bright, when all are in the marketplace. Then he brought forward the prophecy of Joel, nowhere mentioning Christ here, and of the signs of which they were eyewitnesses, or that this had been his promise. For if he had said this, he would have overturned everything and exposed it to scorn; but he first introduces the Father who had promised these things to them through the prophet, and removes the envy; not, he says, to the apostles only, but to every flesh, clearly to those believing sincerely, and with character. For he does not mean the one who says to me, he says, "Lord, Lord," (Matt. 7:21) but the one living a life of the best sort and doing this. He does not add this, making the word of the promise more burdensome and making it light, because the request alone suffices for salvation.
Now, "The sun shall be turned into darkness," and the preceding, "blood and fire and vapor of smoke," these refer to the coming judgment. More appropriately and specifically they speak of Jerusalem and its then captivity, as is shown by the nature of those suffering. Likewise, according to Josephus, many such things foreshadowed the destruction of Jerusalem. That the moon is said to be turned into blood signifies the excess of slaughter, being nearer to the earth and able to suffer this from the exhalation of blood. As for, "before the great and notable day of the Lord shall come," is terrifying and alarming because of the expected dangers. For he says, do not be confident in the fact that you now sin with liberty; but know that these are preludes to that great and dangerous retribution of deeds which will follow, adding, "And everyone who shall call upon the name of the Lord shall be saved." (Rom. 10:13) For Paul the apostle says this was said concerning Christ: but now, since there is no opportunity for that here, in a certain exemption of speech he postponed this.
He refers not to the name of Christ, not to the promise of Christ, but to the promise of the Father. Note also the prudence of Peter. He did not pass over the prophecy in silence, but neither did he speak directly about what concerns Christ: that He, after being crucified and rising again, promised them, the apostles, this gift. If he, Peter, had said this, he would have ruined everything; although this could have proven the Divinity of Christ, it would have seemed incredible. The question, however, is that they should believe what is being said; and that which would have seemed incredible would have caused them to waver. Nothing is able to resolve these perplexities except prophetic testimony. Therefore, when any doubtful question arises, do not resort to reasoning. Rational arguments are refuted just as easily as they are constructed, but who shall destroy the voice of God? Reasoning is destroyed; Scripture is not destroyed.
