text: I understand the need for quality control in the materials used for Holy Communion. We should have some reasonable expectations that bread is bread and wine is wine, without any extraneous additives.
  
  That said, this is one of those times when the letter of the law might be overriding the spirit. Jesus used the bread and wine at hand when he instituted the Eucharist. It was  probably provided by the innkeeper who rented out the 'upper room,' and I doubt he first did a chemical analysis of the product.
  
  But the greater point is that Jesus used common elements. Wheat-based bread and grape-based wine were staples in first century Palestine, but does that mean that for all times and in all places only those materials should be used? I think that's worth discussion.
