In Michael Davies’ book “A Short History of the Roman Mass”, which was a summary of “The Mass: A Study of the Roman Liturgy [London: Longmans, 1912]”, by Adrian Fortesque, Davies makes the comment:
" In a letter to The Tablet, published on 24 July 1971, Father David Knowles, who was Britain’s most distinguished Catholic scholar until his death in 1974, pointed out that
“The Missal of 1570 was indeed the result of instructions given at Trent, but it was, in fact, as regards the Ordinary, Canon, Proper of the time and much else a replica of the Roman Missal of 1474, which in its turn repeated in all essentials the practice of the Roman Church of the epoch of Innocent III, which itself derived from the usage of Gregory the Great and his successors in the seventh century. In short, the Missal of 1570 was, in all essentials, the usage of the mainstream of medieval European liturgy which included England and all its rites.” "
If you believe that the New Rite is an organic development of the Old Rite, you will believe anything, my friend (in a good way). As Cardinal Ottaviani, the former Prefect of the Congregation for the Doctrine of the Faith commented in “A Critical Study of the New Order of Mass”, in September 1969,
“The accompanying critical study of the Novus Ordo Missae, the work of a group of theologians, liturgists and pastors of souls, shows quite clearly in spite of its brevity that if we consider the innovations implied or taken for granted which may of course be evaluated in different ways, the Novus Ordo represents, both as a whole and in its details, a striking departure from the Catholic theology of the Mass as it was formulated in Session XXII of the Council of Trent. The “canons” of the rite definitively fixed at that time provided an insurmountable barrier to any; heresy directed against the integrity of the Mystery”.
Will finish comments later, got to go to work
