Naw...No one ever drank any blood or ate raw meat...No one in Exodus ate raw lambs or drank the blood...
Priests in the Temple did not eat raw meat...It was always cooked...And they certainly didn't drink the blood of the lambs...
So your Eucharist is NOT a real representation of Passover...
If the disciples at the Last Supper would have thought there was actual blood in the cup, they wouldn't have drank it any more than they would have embraced each other in a passionate kiss had Jesus ordered it...They would have immediately lost faith in Jesus as the Lord...
I never said the Eucharist is a representation of the Passover, because the Eucharist is NOT a representation of the Passover. The Jewish Seder is a representation of the Passover.
The Eucharist is related to the Passover, because it was prefigured in the Passover. The Eucharist is a re-presentation of the gift Jesus gave to us by his death. Since the purpose of the death of Jesus is to give us the life of Jesus, we receive the living, risen Christ in the Eucharist.
