The King James bible says that Elijah was taken to heaven. Here is the verse:
"And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and parted them both asunder; and Elijah went up by a whirlwind into heaven"
According to the Orthodox theology, one enters heaven only after the resurrection.The only Saint that is in heaven is The Blessed Virgin Mary. The Saints are not in heaven,but somewhere else.Yet, the above verse is talking about Elija's ascension to heaven, which is not consistent with our dogma.
I am only speculating here, could there be an error in translation?
