The Pope has just reiterated a rule about the Eucharist.
The bread used in the celebration of the Most Holy Eucharistic Sacrifice must be unleavened, purely of wheat, and recently made so that there is no danger of decomposition. It follows therefore that bread made from another substance, even if it is grain, or if it is mixed with another substance different from wheat to such an extent that it would not commonly be considered wheat bread, does not constitute valid matter for confecting the Sacrifice and the Eucharistic Sacrament. It is a grave abuse to introduce other substances, such as fruit or sugar or honey, into the bread for confecting the Eucharist. Hosts should obviously be made by those who are not only distinguished by their integrity, but also skilled in making them and furnished with suitable tools.
The newest rule:
Hosts that are completely gluten-free are invalid matter for the celebration of the Eucharist. Low-gluten hosts (partially gluten-free) are valid matter, provided they contain a sufficient amount of gluten to obtain the confection of bread without the addition of foreign materials and without the use of procedures that would alter the nature of bread.
I remember being inundated with mail from outraged Catholics explaining the nature of the communion wafer: it specifically transformed into the flesh of Jesus when served, although it wasn’t a change of substance but of spirit. And now I learn that Jesus can only be made from wheat, and specifically must include some quantity of gluten, or the magic doesn’t work.
I’m pretty sure that if there were an actual Jesus, son of a god, living in Palestine 2000 years ago, he would not have been made of wheat, and he would have been gluten-free. I’m also pretty sure that the menu from the last supper was not preserved — there are more than enough silly arguments about whether the bread was leavened or unleavened — that for all we know they might have been nibbling on nice slices of pumpernickel, and no Catholic has ever shared the right kind of bread at communion, so they’re all going to hell.
