Justin Martyr — Dialogue with Trypho 49
Trypho: Those who affirm him to have been a man , and to have been anointed by election, and then to have become Christ, appear to me to speak more plausibly than you who hold those opinions which you express. For we all expect that Christ will be a man [born] of men , and that Elijah when he comes will anoint him. But if this man appear to be Christ, he must certainly be known as man [born] of men; but from the circumstance that Elijah has not yet come, I infer that this man is not He [the Christ]. Justin: Does not Scripture, in the book of Zechariah, Malachi 4:5 say that Elijah shall come before the great and terrible day of the Lord? Trypho: Certainly.
Justin: If therefore Scripture compels you to admit that two advents of Christ were predicted to take place — one in which He would appear suffering, and dishonoured, and without comeliness; but the other in which He would come glorious and Judge of all, as has been made manifest in many of the fore-cited passages — shall we not suppose that the word of God has proclaimed that Elijah shall be the precursor of the great and terrible day, that is, of His second advent? Trypho: Certainly. Justin: And, accordingly, our Lord in His teaching proclaimed that this very thing would take place, saying that Elijah would also come.
And we know that this shall take place when our Lord Jesus Christ shall come in glory from heaven; whose first manifestation the Spirit of God who was in Elijah preceded as herald in [the person of] John, a prophet among your nation; after whom no other prophet appeared among you.
He cried, as he sat by the river Jordan: 'I baptize you with water to repentance; but He that is stronger than I shall come, whose shoes I am not worthy to bear: He shall baptize you with the Holy Ghost and with fire: whose fan is in His hand, and He will thoroughly purge His floor, and will gather the wheat into the barn; but the chaff He will burn up with unquenchable fire.' Matthew 3:11-12 And this very prophet your king Herod had shut up in prison ; and when his birthday was celebrated, and the niece of the same Herod by her dancing had pleased him, he told her to ask whatever she pleased. Then the mother of the maiden instigated her to ask the head of John, who was in prison ; and having asked it, [ Herod ] sent and ordered the head of John to be brought in on a charger.
