|August 22, 1994.
In recent years this dicastery has followed closely
the development of the question of the use of low-gluten altar breads
and mustum as
matter for the celebration of the eucharist.
After careful study conducted in collaboration with a number of concerned episcopal
conferences, this congregation in its ordinary session of June 22, 1994, has approved the
following norms, which I am pleased to communicate:
I. Concerning permission to use low-gluten altar breads:
A. This may be granted by ordinaries to priests and laypersons affected by celiac disease,
after presentation of a medical certificate.
B. Conditions for the validity of the matter:
1) Special hosts quibus glutinum ablatum est are invalid matter for the
celebration of the eucharist.
2) Low-gluten hosts are valid matter, provided that they contain the amount of gluten
sufficient to obtain the confection of bread, that there is no addition of foreign
materials and that the procedure for making such hosts is not such as to alter the nature
of the substance of the bread.
II. Concerning permission to use 'mustum':
A. The preferred solution continues to be communion per intinctionem, or in concelebration under the species of bread alone.
B. Nevertheless, the permission to use mustum can be granted by ordinaries to
priests affected by alcoholism or other conditions which prevent the ingestion of even the
smallest quantity of alcohol, after presentation of a medical certificate.
C. By mustum is understood fresh juice from grapes or juice preserved by
suspending its fermentation (by means of freezing or other methods which do not alter its
D. In general, those who have received permission to use mustum are
prohibited from presiding at concelebrated Masses. There may be some
exceptions however: in the case of a bishop or superior general; or, with
prior approval of the ordinary, at the celebration of the anniversary of
priestly ordination or other similar occasions. In these cases the one who
presides is to communicate under both the species of bread and that of mustum, while for the other concelebrants a chalice shall be provided in which
normal wine is to be consecrated.
E. In the very rare instances of laypersons requesting this permission, recourse must be
made to the Holy See.
III. Common Norms
A. The ordinary must ascertain that the matter used conforms to the above requirements.
B. Permissions are to be given only for as long as the situation continues which motivated
C. Scandal is to be avoided.
D. Given the centrality of the celebration of the eucharist in the life of the priest,
candidates for the priesthood who are affected by celiac disease or suffer from alcoholism
or similar conditions may not be admitted to holy orders.
E. Since the doctrinal questions in this area have now been decided, disciplinary
competence is entrusted to the Congregation for Divine Worship and the Discipline of the
F. Concerned episcopal conferences shall report to the Congregation for Divine Worship and
the Discipline of the Sacraments every two years regarding the application of these norms.
With warm regards and best wishes, I am
Sincerely yours in Christ,
Cardinal Joseph Ratzinger, Prefect
