... to defer one's Communion, even at when health problems exist.
(I don't know if it should go to Health & Nutrition or Resistance Movement)
Nowadays, the celiac agenda puts great pressure to the NO Church. Imagine if they do the same with the real Church.
Since Communion is necessary, a disease such as celiac disease with no available cure is an impediment with incredible spiritual consequences. I've read of a case of NO Catholics becoming Protestants due to this.
If you say fragging, then I think that it is not the best method. Fragging decreases the duration of the Presence, especially when there is little tolerance. If you say otherwise, then I share Trosch's words: a thicker host elongates the Presence, but makes the danger of profanation longer. I think that the size of the Particle is proportional to the duration of the Presence.
The Chalice is offered to the laity only in extreme cases. And giving the Chalice to a layman on a Mass is illicit I think. The low-gluten hosts could keep their proportions without a dangerous amount of allergens, but giving attention that they were introduced recently, there is a chance that these "in-between" hosts were a NO invention and thus, tampered.
Also, there is wheat allergy, which calls for the Chalice. Is there a canonically tolerable, hypoallergenic method? Or could it be made? Since these problems are spreading wide, it can clerical defience. So, we should make up resistance against the scarcity of cure, as if it isn't there a really hypoallergenic solution, then celiacs will stay at deaconate.
