"The bodies of Enoch and Elijah have indeed been “taken up,” but they do not yet enjoy complete beatitude, they have not yet been glorified. If by “heaven,” we mean some place “up there” or “out there,” we can say that the bodies of Enoch and Elijah are “heaven” – meaning that they are not on this earth, but have been taken away to some other place, we know not where. However, when we speak of “heaven,” we usually mean the state of eternal bliss, complete union with God – in this sense, the bodies of Enoch and Elijah are not in heaven; only the bodies of Jesus and Mary are there. [as to the question of whether a body can be in heaven, since heaven is not primarily a place, please consider my earlier article on Mary’s Assumption – simply put, heaven is a place insofar as considered in relation to the two bodies of Jesus and Mary, but there is no “containing place” or “region” of heaven]

Both Enoch and Elijah enjoy beatitude of soul, hence we must admit that their soul’s are “in heaven,” insofar as they enjoy the vision of God. Nevertheless, though their souls are still united to their bodies – they have not yet died – their bodies do not enjoy the perfect beatitude which will be given in the resurrection of the dead. The bodies of Enoch and Elijah have not yet been glorified, this is a grace given only to Jesus and Mary. Thus, we say that Enoch and Elijah are in heaven in regard to their souls, but are in a sort of “paradise” in regard to their bodies."

"Enoch and Elijah are not in the state of beatitude...they do not yet have glorified bodies. Since they are not glorified, they cannot be in "uncontained place" in or "glorified place". Thus, they are not yet in heaven bodily, though they are spiritually in heaven, since their souls are in perfect happiness. They are still alive, that is, they have never died. So they still live something of a 'natural existence' -- it is a miracle, of course."
