The great Russian Orthodox theologian Sergius Bulgakov says this about the Fall in Genesis 1-3:
"An event is described that lies beyond our history, although at its boundary. Being connected with our history, this event inwardly permeates it. But this event cannot be perceived in the chain of empirical events, for it is not there. It took place, but beyond the limits of this world: After the expulsion of our progenitors from Eden, its gates were locked, and an angel with a fiery sword protects this boundary of being that has become transcendent for us. But this event took place precisely in this world, or at least for this world."
(Sergius Bulgakov, The Bride of the Lamb (2002), 170)
