I will embed in RED, my comments to Bishop Kemme's excellent treatise on what he expects for liturgies in his diocese. But let me say a couple of things.
The Mass, since Vatican II, as we all know and have experienced, is more clerical than it ever was prior to the Council. Bishops and priests make up their own rubrics or dismiss the rubrics present in the modern Mass in a minimalist way--that's clericalism especially if the words of the Mass are changed to suit the priest or bishop.
Part of the clericalism is placed on steroids given the legitimate options in the Mass which include variations on the penitential act and which one is chosen and who chooses. The same with the Eucharistic Prayer, the Mystery of Faith acclamation. One can chant the propers, aka, introit and other antiphons, but other options allow something similar or completely different.
But the one thing that trumps all other problems with the Modern Mass boils down to taste! A variety of styles of music and instrumentation, which are all over the place, in terms of options, makes the chanting of the Mass based upon taste, not tradition. And whose taste? We all know what kind of music we all like. To demand that my likes be included and my dislikes be removed is the height of clericalism. But that's the modern Mass.
What is sung and how it is sung in the Mass has caused me more stress as a priest than any other liturgical issue.
Let's face it, many who have an opinion on music for the Mass, prefer kitsch to art. And they prefer it in a vociferous way!
Let's dig into Bishop Kemme's pastoral letter on the liturgy with my astute comments embedded in RED.
