My mom who comes to church with us every week for the last 6 months or so has been harping about the leavened bread that some churches use. I sometimes wonder why she comes with us because she criticizes so much. I wouldn't, but I have had moments when I felt like saying that maybe she should go back to the hall.
Anyway the thought occured to me, why do witnesses use unleavened bread and fermented wine? Most churches that I know of use unleavened bread and grape juice. The greek word (I believe oinos) for wine could be either fermented or unfermented. Could Jesus have used unfermented wine? (fruit of the vine) It makes much more sense.
