Elijah is indeed coming

In those days,
like a fire there appeared the prophet Elijah
whose words were as a flaming furnace.
Their staff of bread he shattered,
in his zeal he reduced them to straits;
By the Lord’s word he shut up the heavens
and three times brought down fire.
How awesome are you, Elijah, in your wondrous deeds!
Whose glory is equal to yours?
You were taken aloft in a whirlwind of fire,
in a chariot with fiery horses.
You were destined, it is written, in time to come
to put an end to wrath before the day of the LORD,
To turn back the hearts of fathers toward their sons,
and to re-establish the tribes of Jacob.
Blessed is he who shall have seen you
and who falls asleep in your friendship.

Matthew 17:9-13

As they were coming down the mountain, Jesus ordered them, “Tell no one about the vision until after the Son of Man has been raised from the dead.” And the disciples asked him, “Why, then, do the scribes say that Elijah must come first?” He replied, “Elijah is indeed coming and will restore all things; but I tell you that Elijah has already come, and they did not recognize him, but they did to him whatever they pleased. So also the Son of Man is about to suffer at their hands.” Then the disciples understood that he was speaking to them about John the Baptist.
