Here's more on Melchizedek in scripture:
That link you provided is interesting because it puts Ephraim in America but has a different take on Jesus than the sources I'm providing. For example, have you looked at my example provided in the Templar's thread with Magdalen (it relates to Christ-Jesus-Michael terminology, but also actual personal experience with it)?
I'd be interested in learning more about these Lost Books of Eden.
Does it discuss the earlier Sethite priests as doctor-physician-priests. My understanding is these Sethite priests are what links the aproximately 30,000 period between the Gardens of Adam and Eve and the appearence of Melchizedek after them.
Going back further it would be Van (who settled at the south of the Caspian Sea) who links the loyal people from the times of rebellion to the coming of Adam and Eve. Do you have anything related to this?
