Canon 9.
If anyone says
- that the rite of the Roman Church, according to which a part of the canon and the words of consecration are pronounced in a low tone, is to be condemned;
- or that the mass ought to be celebrated in the vernacular tongue only;[28]
- or that water ought not to be mixed with the wine that is to be offered in the chalice because it is contrary to the institution of Christ,[29]
I wonder how many problems could be solved by just looking through the canons of the Councils...
