The rule is that the host must contain enough wheat so that it retains the “confection” of bread. The Benedictine Sisters worked for YEARS to get this right - enough wheat to consecrate the Host, but not enough to cause a celiac to react. It was really a miracle that it happened at all.
Story of the Low Gluten Hosts
Yes, any celiac or gluten intolerant Catholic can receive the Precious Blood, IF it is offered. The Mass my son and I sometimes attend does not have enough EMs to distribute the cup, so he misses receiving during that Mass. And of course on Good Friday no wine is consecrated. Sometimes randomly, the cup will not be distributed. It isn’t perfect, but it usually works.
I do have some of the very low-gluten hosts and a pyx to put them in, but neither of my sons seems to want to draw that much attention to themselves, to approach the priest and work out a procedure to receive it. Their choice.
The article does not speak very well of the family’s formation of their faith, since they are implying to their daughter that she is not receiving the Body, Blood, soul and divinity of Jesus through his Blood. There is nothing “less than” about receiving one species or another. Most Catholics my age NEVER received the Precious Blood and we never felt it was only half of Jesus.
Also, for this young girl to pronounce the taste of the very low gluten hosts “disgusting” is pretty insulting. The regular gluten-containing host is not flavorful - what does she expect? A Pop-Tart?
