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.
Well; that’s ONE way to try to slip thru the facts.
