Cardinal Walter Brandmüller was interviewed by Vatican Insider last month. His last answer, reproduced below, is revealing.
I must emphasise that the form of the post-conciliar liturgy with all its distortions, is not attributable to the Council or to the Liturgy Constitution established during Vatican II which by the way has not really been implemented even to this day. The indiscriminate removal of Latin and Gregorian Chants from liturgical celebrations and the erection of numerous altars were absolutely not acts prescribed by the Council.
With the benefit of hindsight, let us cast our minds back in particular to the lack of sensitivity shown in terms of care for the faithful and in the pastoral carelessness shown in the liturgical form. ... Excesses which catapulted numerous faithful into total chaos, leaving many fumbling around in the dark.
Just about anything and everything has been said on this subject. Meanwhile, the liturgy has come to be seen as a mirror image of Church life, subject to an organic historical evolution which cannot - as did indeed happen - suddenly be changed by decree par ordre de mufti. And we are still paying the price today.
