I understand that; Catholics are about the only folks that believe we are partaking of the literal body of Christ. The fundamentalists (with whom AG identified herself, and to which VadeRetro was referring in his response to her post) typically do not partake of wafers in communion.
I hadn't known about the oyster cracker thing, though. Seems a bit improper, consider Jesus was a Jew and oysters were unclean (I know, I know -- there aren't any oysters in oyster crackers; that's why I used the term "improper" rather than "sacriligeous").
Many Baptist churches use wafers, Junior.
