Canon law states that bread used for Holy Communion must be made from wheat and water in order for transubstantiation to occur. A process which, according to Catholic teachings, is when bread and wine is transformed into the body and blood of Jesus.
Vatican City, Jul 11, 2017 / 03:01 am (CNA/EWTN News).- The norms regarding gluten and Communion hosts that went viral this weekend are nothing new in the Catholic Church.
On Saturday morning, the Congregation for Divine Worship and the Discipline of the Sacraments issued a circular letter to bishops reiterating existing norms regarding the matter of the Eucharist, including the norm that Communion hosts must contain some amount of gluten to be valid matter for consecration.
By Saturday night, the (misconstrued) news had spread like wildfire: “Catholic Church bans celiacs from Communion!” many media outlets declared. It was such a hot topic that Twitter declared it a “moment” in world news.
But these were existing norms – there was no change, no announcement of new norms, nor banning of celiacs from the Sacrament of the Eucharist. Gluten-free hosts have always been invalid matter for the sacrifice of the Mass, meaning that Catholics with celiac disease have already grappled with other options for Communion.
Usually, such “reminder” letters are issued when someone, generally a bishop, has raised a question or has been alerted of a possible abuse of the norm.
Still, the letter left lingering questions regarding people with celiac disease (or those with other serious allergies to wheat) and Communion. Here’s what the Church, and Catholics with celiac disease, have to say about going gluten free for Communion.
Wheat bread and wine of the grape are the matter of the sacrament of the Eucharist because Christ instituted the sacrament under these species. Moreover, Christ compared himself to a grain of wheat, and to the vine.
At some point along the line the question of gluten came arose, and whether the bread used for Holy Communion necessitated at least some gluten (and its accompanying protein gliadin) to be considered wheat bread that was valid matter for the sacrament.
A July 2003 circular letter from the Congregation for the Doctrine of the Faith, noting documents from the 1980s and ’90s, recalled that “Hosts that are completely gluten-free are invalid matter for the celebration of the Eucharist.”
It added that “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.”
And in 2004 the Congregation for Divine Worship wrote in its instruction Redemptionis Sacramentum that “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.”
That said, the Church recognizes that it mustn’t exclude from receiving Communion Catholics with celiac disease, and has made accommodation for those who are unable to consume normal bread.
