The bread Jesus used at the Last Supper was not gluten free. Therefore the gluten free hosts are NOT the true Christ. Ask your bishop.
I listen to Relevant Radio and they talked about this. Per the Church, non gluten hosts do not become Christ.
I’m alcoholic, and I can’t take the wine.
"Now there is another choice. The Benedictine Sisters of Perpetual Adoration in Clyde, Missouri, have developed a Communion host that is extremely low in gluten. They have worked for ten years on this project. The host is made from gelatinized wheat starch. The hosts have been tested for the presence of gluten. According to the Sisters, they were tested to a level of 0.01% gluten. At that level, the lowest that could be tested, no gluten was detected. This means that there is less than 0.01% gluten in one of these hosts; however, it is not known how much less.
"The Secretariat for the Liturgy of the United States Conference of Catholic Bishops has stated that these meet the requirements of the Code of Canon Law and may be validly used at Mass with permission of the person’s pastor. They are manufactured by hand in a separate facility from the ordinary wheat hosts and are shipped separately from the wheat hosts so that there is no danger of cross contamination."
They've got more details at the site. I found this at catholicCeliacs.org
