I had a question emailed to me recently asking about what Jesus would have used for the bread and wine during the last supper. Of course, those are the elements that make up our communion, or memorial. The bread He used would have been the matzoh prepared for Passover specifically. At the time, it was hand made, without yeast (which represents sin).
The wine used was probably a bit weaker than our modern wine, but because of the fermentation process and the time in which Jesus lived, it surely did contain alcohol. As for what we “should” use today, or the closest we could get, would probably be Kosher for Passover matzoh and for Passover wine as well.
I don’t believe we should be legalistic about the elements used; however, the symbolic nature of these specific elements always help me to focus on Christ, and to see how He completes the images of Passover. Here is one of my articles that goes into the details of Matzoh: The Bread As for what a church can use, I personally think some type of unleavened bread is only proper, though, again, it is a symbol and not to be turned into something legalistic. I personally think members should be given a choice between juice and wine, since there are good reasons why some people don’t drink, as well as juice being available for those under 21.
