Question: "Was John the Baptist really Elijah reincarnated?"
Matthew 11:7–14 declares, “Jesus began to speak to the crowd about John: ‘What did you go out into the desert to see? A reed swayed by the wind? If not, what did you go out to see? A man dressed in fine clothes? No, those who wear fine clothes are in kings’ palaces. Then what did you go out to see? A prophet? Yes, I tell you, and more than a prophet. This is the one about whom it is written: “I will send my messenger ahead of you, who will prepare your way before you.” I tell you the truth: Among those born of women there has not risen anyone greater than John the Baptist; yet he who is least in the kingdom of heaven is greater than he. From the days of John the Baptist until now, the kingdom of heaven has been forcefully advancing, and forceful men lay hold of it. For all the Prophets and the Law prophesied until John. And if you are willing to accept it, he is the Elijah who was to come.’” Here Jesus quotes from Malachi 3:1, where the messenger appears to be a prophetic figure who is going to appear. According to Malachi 4:5, this messenger is “the prophet Elijah,” whom Jesus identifies as John the Baptist. Does this mean that John the Baptist was Elijah reincarnated? Not at all.
First, the concept of reincarnation would have been foreign to the Jewish mindset, and faithful Jews would have rejected the idea of reincarnation out of hand. Besides, Elijah did not die; he was taken to heaven in a whirlwind as he rode in a chariot of fire (2 Kings 2:11). Arguing for a reincarnation (or a resurrection) of Elijah misses that point. If anything, the prophecy of the Elijah “to come” would have been viewed as Elijah’s physical return to earth from heaven.
Second, the Bible is quite clear that John the Baptist is called “Elijah” because he came in the “spirit and power of Elijah” (Luke 1:17), not because he was Elijah in a literal sense. John the Baptist is the New Testament forerunner who points the way to the arrival of the Lord, just as Elijah filled that role in the Old Testament (and might again in the future—see Revelation 11).
Third, Elijah himself appears with Moses at Jesus’ transfiguration after John the Baptist’s death. This would not have happened if Elijah had changed his identity into that of John (Matthew 17:11–12).
Fourth, Mark 6:14–16 and 8:28 show that both the people and Herod distinguished between John the Baptist and Elijah.
Finally, proof that this John the Baptist was not Elijah reincarnated comes from John himself. In the first chapter of John the Apostle’s gospel, John the Baptist identifies himself as the messenger of Isaiah 40:3, not as the Elijah of Malachi 3:1. John the Baptist even goes so far as to specifically deny that he was Elijah (John 1:19–23).
John did for Jesus what Elijah was to have done for the coming of the Lord, but he was not Elijah reincarnated. Jesus identified John the Baptist as Elijah, while John the Baptist rejected that identification. How do we reconcile these two teachings? There is a key phrase in Jesus’ identification of John the Baptist that must not be overlooked. He says, “If you are willing to accept it, he is Elijah.” In other words, John the Baptist’s identification as Elijah was not predicated upon his being the actual Elijah, but upon people’s response to his role. To those who were willing to believe in Jesus, John the Baptist functioned as Elijah, for they believed in Jesus as Lord. To the religious leaders who rejected Jesus, John the Baptist did not perform this function.
