Matthew 17:12
Douay-Rheims
But I say to you, that Elias is already come, and they knew him not, but have done unto him whatsoever they had a mind. So also the Son of man shall suffer from them.
Origen
That He says of John, Elias is already come, is not to be understood of the soul of Elias, that we fall not into the doctrine of metempsychosis, which is foreign to the truth of Church doctrine, but, as the Angel had foretold, he came in the spirit and power of Elias.
