Yesterday evening my husband had a meeting with teenagers from different religions. There was a Torah scroll and my husband had taken the silver cup and plate we use for the Eucharist. My husband told the story of the last supper, how Jesus and his friends came together, shared bread and drank from the cup.
Then a boy of twelve asked: “Was it this cup, this one here, that Jesus and his friends used?”
With his words he said exactly what the Eucharist is about. It is the same cup.
