GoodSamaritan:
A story about an 8 year old girl who is deathly allergic to gluten, which is in wheat. Her First COmmunion was invalidated because she did not take a wheat wafer–is this legalism at its’ worst?
“Legalism”? No.
In order to be valid, the bread used for the Eucharist
must be made of
only wheat and water.
Roman Catholic tradition also calls for
unleavened bread, however, if leaven is used, the Eucharist is only illict, not invalid (and, our Eastern Catholic and Orthodox brethern do use leavened wheat bread for their Communion).
If a priest attempts to use anything other than wheat bread, then the validation of the Eucharist according to the Church
cannot objectively happen – no matter how much the priest/recepient may intend it or how clearly the priest says the words of Consecration (the requirements for a valid sacrament are proper matter, proper form, and proper intent–the lack of any one of those means that the sacrament is no longer valid)
This is not legalism on the part of the Church, but the Church’s recognition that the Church does not have the authority to change the matter required for the confection of the sacrament. Jesus used bread and wine – the Church does not feel it has the authority to change this.
If the Church were not strict about this, you would find all sorts of abuses going on, such as attempted consecration of pizza or grape juice.
Those who suffer from disease or intolerance towards gluten (found in wheat) are able to either partake A) only of the Precious Blood (the complete reality of the Eucharist is present in both the Host and Cup – only one is required to receive Communion) or B) through the use of low-gluten hosts, wheat hosts that are specially manufactured in order to be able to be tolerated and still ok to use under Church law.
In the case in NJ that you are referring to, the mother was offered both of these options and refused! Her daughter could have only received of the Precious Blood and been perfectly fine. Instead, another priest contacted her and offered to do it instead, in defiance of Church teaching

and tried to consecrate a rice wafer – something that is not in the wheat family and is therefore not only illict, but completely invalid. Therefore – the Church has ruled that the child’s Communion was invalid and other arrangements will have to be made (ie, she will either have to only receive the Precious Blood or receive Communion with a consecrated
approved low-gluten host.)
Hope this helps,
