Editing Must (section)

===Liturgical norms===
The latest document from the [[Dicastery for the Doctrine of the Faith|Congregation for the Doctrine of the Faith]] on the matter, issued on 24 July 2003, gave the following norms, which simplify those previously in force:<ref name=CDF/>

<blockquote>The [[Ordinary (church officer)#Catholic usage|ordinary]] is competent to give permission for an individual priest or layperson to use mustum for the celebration of the Eucharist. Permission can be granted habitually, for as long as the situation that occasioned the granting of permission continues (e.g., the priest is an alcoholic).

When the principal celebrant at a concelebration has permission to use mustum, a chalice of normal wine is to be prepared for the concelebrants.

Given the centrality of the celebration of the Eucharist in the life of a priest, one must proceed with great caution before admitting to Holy Orders those candidates unable to ingest alcohol without serious harm.

Attention should be paid to medical advances in the area of alcoholism and encouragement given to the production of unaltered mustum.</blockquote>
