Was elijah john the baptist?
What is making you think that? They’re two separate people.And if I recall, the Church lists them as two separate saints.
NO! The Church clearly teaches there is no such thing as reincarnation.
CCC 1013 Death is the end of man’s earthly pilgrimage, of the time of grace and mercy which God offers him so as to work out his earthly life in keeping with the divine plan, and to decide his ultimate destiny. When “the single course of our earthly life” is completed, we shall not return to other earthly lives: “It is appointed for men to die once.” There is no “reincarnation” after death.
No, Elijah returns in his own body as one of the witnesses against antichrist.
Elijah, remember, took his HUMAN BODY to Heaven with him. And you can’t reincarnate (if this were possible) without being dead!
What did Jesus mean when He said of John, “Elijah has already come?”
Not literally. But, like Jesus said, he was the prophet whose appearance was foretold.
This link says that John was the fulfillment of the Elijah expectation. But they are not the same person.
