I can understand the thought process you present about 'visions', and it is something to consider.
Usually when a person in scripture is witnessing a 'vision' they are in sleep or trance-like state of being.
I don't see that as being the case when the disciples saw Jesus with Moses and Elijah.
It is written as if they are fully awake and aware, even to the point of being worried if they should build a tent for them.
And they hear the voice of the LORD and are so afraid that they fell on their faces.
None of this seems to imply that they were asleep or in a trance when this took place.
What type of body they had when the disciples saw them is unknown.
It is a good assumption to think their old flesh bodies were still in the grave, as was David's.
It is my assumption that what the disciples saw was their spirits, and not their resurrected bodies.
One of those rare instances when the human eye can see the spiritual realm, as when Elijah saw the army of angels all around him and asked GOD to open the eyes of his servant so he could see them also. 2 Kings 6:17
It was really happening, and was not just a dream.
But I leave my options open for further study.
I have seen or heard many types of explanation as to the importance of this story, and what it's intended message revealed.
They seem incomplete to me, as if there is something more to the story.
I don't think John the Baptist being spoken of as Elijah has anything to do with this story.
As he is said to have come in the spirit of Elijah. Luke 1:17
Good study!
Thanks for your responses.
Thank you for the kind style of response. We need more of that on these boards.

I'm not sure how relevant that consideration may be. It's not a question of whether the disciples all saw the same thing, and I don't think it matters whether the vision reached them through their eyes or whether it was directly overlaid on top of their brain. Likewise, it could be a physical manifestation or vision granted of the spirit realm, such as the case of Elijah that you mentioned. The elements that I note are:
1) that to be consistent with other parts of scripture, there is no life outside of resurrection.
2) that although it is with God's prerogative to raise ahead of schedule for a specific purpose and as such remains a possibility, this would be a special exception, rather than the rule (Matthew 27:52-53)
3) the more pressing implication of the term
vision, to me, is that whatever they saw likely had symbolic meaning
I recognize that point one (1) above may be subject for debate considering the nature of this thread. However, regardless of where one stands on that point, I acknowledge that it could be possible that this was the literal Moses and Elijah, specifically raised for this appearance.
Yet, I think this is unlikely, considering the nature of visions in general. If we consider the most well known vision of the entire scripture, the book of Revelation, it is filled with images of people and things. While some of these people and things are most certainly real, the images of them likely were not. For example,
1) Horses are real things. Yet I think it is unlikely that God recruited real horses to play their parts with the Four Horsemen of the Apocalypse
2) I acknowledge that Jesus Christ is most certainly real, and I believe that he personally spoke at parts within the vision. However, I am inclined to think that the parts with him appearing in the clouds and destroying armies didn't require him as a live action participant, destroying real people just to make the scene.... a scene which is set in a future setting, mind you.
Thinking of this vision on the Mount of Transfiguration in a similar vein as the vision in the book of Revelation, I am inclined to think that the figures of Moses and Elijah were symbolic elements of the vision. That the vision had symbolic meaning is evident in Jesus's response to his disciples, which seems to indicate that they didn't understand what they had seen.
But regardless of how the vision is interpreted, it doesn't establish that Moses or Elijah were ever in heaven (the abode of God) in any form at any time. Even if we grant that these were real manifestations of the original people, they were seen on the earth, not in heaven. The given details of the event don't contradict either opinion. Like you said, it's not given to us in any complete sense.
