way to Rome. Can grape juice be used for communion?
heard that we consider the grape juice a kind of wine, but they wanted to know more. So the question went back to the priest and Rabbi Twersky. R’ Twersky sent back a citation of a responsum of R’ Moshe Feinstein, allowing the use of grape juice for the seder. The Vatican concluded that if grape juice is okay for the seder, then it was usable for the Last Supper, and therefore when Jesus said at that meal “this is my blood” he meant grape juice too.
