I have never heard anyone make the connection of Enoch or Elijah as a representative of the entire people of God. They were individuals - they do not indicate to us that WE TOO will follow. At best, they tell us that ONLY A VERY SELECT FEW WILL BE SAVED! Not much hope for you and I! But with Mary, Revelation 12 clearly makes the connection, among other places, that Mary is a type of the Church, the People of God. Being part of Mother Church, we see our own future in the Woman of Revelation 12 - and we see Mary herself, the Ark of the New Covenant.
I think this is clearly in the Bible and the first Christians found it when looking at how God worked during the time of Christ. Thus, we see the first Christians speaking of Mary in such a way that we don't see explicitly in Scriptures.
I think where you are having difficulties is the artificial concept that only things in the Scriptures are valid to believe. Christianity never would have gotten off the ground with that idea floating around. We'd still be circumcising, because the Scriptures do not give the Apostles the mandate to do away with circumcision. Yet, the Church, given the power to bind and loosen, DESPITE the Old Testament commands, loosened the requirement for men to be circumcised before entering into the Church.
Once you see how God expresses Himself through the Word and the Living Church, it will become more clear to you.

I didn't expect you to get it.
The discussion was about the assumption of Mary your church professes. My point was straightforward. We have only 2 examples in Scripture of human beings that did not suffer death, Enoch and Elijah. The theory of Mary's assumption is not in Scripture. If you wish to build a doctrine around assumption and it's significance you should look to those that actually were assumed into heaven.
