Here is a wonderful homily on the "traditional" Latin Mass (Extraordinary Rite as it is now called). Some of the things mentioned seem to me to be very important. I will not go on at length about recent mistakes of the past. Many people now accept that the Roman Liturgy suffered from a kind of "iconoclasm" since some of the symbolism (much of it obviously scriptural) was simply removed, being judged unnecessary (might as well link that with the Archduke's criticism of Mozart - "two many notes").
More and more through celebrating the "old" Rite and also celebrating now and then the Ordinary Rite in Latin and Ad orientem, I am coming to believe that this is the preferred way. I am conscious of the wider use of the vernacular, encouraged by Vatican 11, but we also need to remember that Latin was recognised as the primary language of worship. I have no problem with the principle of vernacular liturgy (and the Missal we have now is a definite improvement although not as good as it might have been, in my opinion). I have no problem with celebrating Mass in English, but it should never have become the prominent way of celebrating the liturgy, and I am now of the strong opinion that the priest should either turn to the East (symbolically at least since many churches are not built that way) or that, as The Pope, Cardinal Ratzinger argued and suggested, a large crucifix should be placed on the altar with the corpus facing the priest. I know some will disagree with all this, and I would have done, and did some years ago. Listen to the homily at the link if you can and allow for the possibility that just maybe we made some mistakes in the recent past. I wonder if we will ever be able to put things right.
