To me this doesn't sound like three parishes in one city had priests who had an alcohol problem; that's just too high a percentage. It sounds more like priests I've known who thought themselves a wine connoisseur who brought in their flavour of the month wine.
In his letter, Naumann ordered all clergy to “immediately discontinue use of all wines that have not been specifically produced to meet the requirements for sacramental usage.” Naumann noted that a number of readily available products that “contain additives such as elderberry extract, sugars, alcohol, etc.” are invalid matter for the Mass. Thus, their use would also mean that the Mass is invalidated.
My problem with this whole thing is that Masses were declared invalid. Did people then not fulfill their Sunday duty? What about receiving Holy Communion? Did the invalid matter for wine negate the matter of the host?
Continuing, he noted that the situation had been thus for many years, stating that, “for any number of years all Masses were invalid and therefore the intentions for which those Masses were offered were not satisfied, including the obligation pastors have to offer Mass for the people.”
All those graces ...LOST!
