"You're going to notice that the form of Eucharist, which is as valid as the other, if physically and literally bread. Why do we do that? Why don't we use the wafers or hosts? Not that either one is more valid or better or worse than the other."So the bread baking ministry is not primarily about service to the community, it's primarily for the benefit of the bakers themselves.
"We do it because we find that the ministers themselves, who bake the bread, have shared with us over the years that they're more able to enter more fully, because their hands have been part of what is happening in terms of the Consecration. There's the bread they've prepared."
In addition, you recall the Symmetric Property of Equality,
"We also feel that it is more symbolic and representative of what actually happened with Christ during the Last Supper itself."Or more likely he referred to hosts in a Seinfeldian "Not that there's anything wrong with that" sense.
