The Last Supper an incredible metaphor.
When we look at this ritual, we must not think it is a literal act, but rather it is something that points the way to a greater understanding.
The broken bread is YOU.
It is the Christ nature that willingly broke its immortal essence, surrendering it to the mortal realm of death and suffering.
It is thereby “swallowed” into the belly of being a human, a mortal human being.
According to Romans 3:13 the throat is an "open grave" therefore in this ritual, the broken nature of Christ descends through the portal of the grave into the belly of Sheol - the mortal realm where every manner of evil exists.
We are to DO THIS IN REMEMBRANCE OF ME (the Christ - YOU).
As we practice the ritual we remember that it is OUR JOURNEY into human consciousness and mortality.
Remember in the movie titled, "The Notebook” the author of the notebook is Ally who has dementia, Alzheimers Disease. When diagnosed she begins to write her life’s story in the notebook so that she will NOT FORGET.
She does forget but her husband reads the stories to her until one day she exclaims, THIS ABOUT US!!!
It is the same way with the Bible - it is our journey into human consciousness with stories that depict, with graphic imagery, OUR OWN DEVOLUTION INTO DENSE HUMAN CONSCIOUSNESS and our ultimate AWAKENING and realization that this grand book is talking about US. The human race that has forgotten its DIVINE - HOOD having surrendered its memory to become totally invested into CREATURE - HOOD.
There is a purpose for Divinity to invest itself into the biological framework. This is the story of Mary, as she was overshadowed and penetrated by the divine so that Mary (THE WHOLE HUMAN RACE) would one day bring to bear the creation that is both GOD AND MAN a perfect vehicle from which to experience and occupy all of the material worlds.
