16. Yet would I not trust the interpretation of the Jews alone, were it not confirmed by Christ, Matthew 10:10ff. When, on Mount Tabor, the disciples saw Elijah and Moses, they said to the Lord, “Why then say the scribes that Elijah must first come?” They meant to say, “You have already come; yet Elijah has not come first, but only now, after you: and was it not said that he was to come before you?” This interpretation was not rejected, but confirmed by Christ, who said, “Elijah truly shall first come, and restore all things. But I say unto you that Elijah is come already; and they knew him not, but have done unto him whatsoever they listed.” Then the disciples understood, says St. Matthew, that he spoke of John the Baptist.
St. Mark likewise says, Mark 13, “But I say unto you that Elijah is come, and they have done unto him whatsoever they would, even as it is written of him.”
17. Now there is no other prophecy concerning Elijah’s coming but this one of Malachi, and Christ himself applies it to John. Thus it has no force if someone were to object, Christ says that Elijah is to come first and restore all things, for Christ interprets his own words by saying, “But I tell you that Elijah is come” etc. He means to say, It is right and true what you have heard about Elijah, that he is to come first and restore all things; thus it is written and thus it must come to pass. But they do not know of which Elijah this is said, for he is come already. With these words, therefore, Christ confirms the Scriptures and the interpretation concerning the coming Elijah, but he rejects the false interpretation concerning an Elijah other than John.
18. Most strongly, however, does Christ assert, Matthew 11:13ff., that no other Elijah is coming. He says, “All the prophets and the law prophesied until John. And if you will receive it, this is Elijah, that is to come. He that hath ears to hear, let him hear.” Here it is made clear that but one Elijah was to come. Had there been another he would not have said, “John is Elijah who was to come,” but he would have had to say, “John is one of the Elijahs,” or simply, “He is Elijah.” But by calling John that Elijah whom everybody expects, who, doubtless, was announced to come, he makes it sufficiently clear that the prophecy of Malachi is fulfilled in John, and that after this no other Elijah is to be expected.
19. We insist, therefore, that the Gospel, through which Christ has come into all the world, is the last message before the day of judgment; before this message and advent of Christ John came and prepared the way. And although all the prophets and the law prophesy until John, it is not allowed to apply them, neglecting John, to another Elijah who is yet to come. Thus also the prophecy of Malachi must fit the times of John. He carries the line of the prophets down to John’s times and permits no one to pass by. — And so we conclude with certainty that no other Elijah is to come, and that the Gospel will endure unto the end of the world. “Art thou the prophet? And he answered, No.”
