From a reader:
I wanted to know your opinion about low gluten hosts and the use of them at the Mass both Novus Ordo and the Traditional Latin Mass.
My girlfriend has Celiac disease and cannot receive the Blessed Sacrament under the form of the Precious Body.
This makes it difficult when she wishes to attended and learn more about the Old Mass but cannot receive Holy Communion. She is very much aware that she could pray a spiritual communion, but she still has a desire to receive Holy Communion. I have heard from some people that they do not like low gluten hosts because they are "man made" and not natural. I feel it is ok to use them so that way all can receive Holy Communion.
Regular hosts are man-made too. There are no host bushes.
The Church has made it clear that a certain type of approved low-gluten Host may be validly and licitly consecrated. (Cf. Congregation for Doctrine of the Faith, July 24, 2003, Prot. 89/78-174 98.)
If it can be validly and licitly consecrated during Holy Mass with the Novus Ordo, it may also be validly and licitly consecrated during a TLM.
You should approach the priest who celebrates the TLM and ask him to consecrate a low-gluten host when she is present. Actually, make arrangements ahead of time. Offer to obtain them for him, so that he does not have to do the extra footwork. If necessary you could also ask support from the local bishop, whom I am sure will give you a sympathetic hearing.
The same would apply to the sort of wine used for Holy Mass: mustum could be used by priests who have a problem with alcohol.
I stress that the hosts and mustum must be made by approved sources. I don’t happen to know off the top of my head what those sources are, but I am sure that readers can chime in with concrete information. Any good church goods store would know. Try Leaflet Missal in St. Paul. They have a great guy in church goods.
