So much of what progressive liturgists used as their apologetic for the new Mass denigrated so much of the older Mass, including the role of the ordained priest, mysticism, reverence, etc. All of these things, seen by so many progressive liturgists as backwardism and contrary to the Holy Spirit today, are maintained in the Eastern Rites of the Church to this very day.
There has always been a certain kind of clericalist arrogance in the Latin Rite when compared to the Eastern Rites, although the ethos of the pre-Vatican II Mass and most Eastern Rites today is almost identical.
But progressive arrogance about the Modern Roman Missal is breathtaking especially their denigration by proxy of the Eastern Rites of the Church as well as Eastern Orthodoxy’s similar, in fact, identical liturgy.
