Pope Benedict is perfectly clear about what will remain the normative Mass and how the normative Mass can be renewed by the profound, foundational reverence of the 1962 Missal!
LETTER OF HIS HOLINESS
TO THE BISHOPS ON THE OCCASION OF THE PUBLICATION
OF THE APOSTOLIC LETTER "MOTU PROPRIO DATA"
ON THE USE OF THE ROMAN LITURGY
PRIOR TO THE REFORM OF 1970"
...The use of the old Missal presupposes a certain degree of liturgical formation and some knowledge of the Latin language; neither of these is found very often. Already from these concrete presuppositions, it is clearly seen that the new Missal will certainly remain the ordinary Form of the Roman Rite, not only on account of the juridical norms, but also because of the actual situation of the communities of the faithful.
It is true that there have been exaggerations and at times social aspects unduly linked to the attitude of the faithful attached to the ancient Latin liturgical tradition. Your charity and pastoral prudence will be an incentive and guide for improving these. For that matter, the two Forms of the usage of the Roman Rite can be mutually enriching: new Saints and some of the new Prefaces can and should be inserted in the old Missal. The “Ecclesia Dei” Commission, in contact with various bodies devoted to the usus antiquior, will study the practical possibilities in this regard. The celebration of the Mass according to the Missal of Paul VI will be able to demonstrate, more powerfully than has been the case hitherto, the sacrality which attracts many people to the former usage. The most sure guarantee that the Missal of Paul VI can unite parish communities and be loved by them consists in its being celebrated with great reverence in harmony with the liturgical directives. This will bring out the spiritual richness and the theological depth of this Missal.
