Liturgical reform wasn’t so much about bringing a modern tone to the Mass so much as better facilitating the understanding and aprticipation of the laity:
The rite of the Mass is to be revised in such a way that the intrinsic nature and purpose of its several parts, as also the connection between them, may be more clearly manifested, and that devout and active participation by the faithful may be more easily achieved.
1962 Missal indult notwithstanding, Catholic traditionalists will probably need to come to terms with the liturgical teachings of the Council, such as this one:
For this purpose the rites are to be simplified, due care being taken to preserve their substance; elements which, with the passage of time, came to be duplicated, or were added with but little advantage, are now to be discarded; other elements which have suffered injury through accidents of history are now to be restored to the vigor which they had in the days of the holy Fathers, as may seem useful or necessary.
Simplification need not impact what many Catholics hold dear, namely beauty, awe, and a sense of sacrifice in the liturgy. Through the 1970 Missal, the first steps toward this restoration of vigor were taken. If the implementation has been faulty at times and in places, it is neither the fault of the Council, nor a shortcoming of these documents, so much as human error. The same error led to liturgical abuses and ennui before Vatican II, and there’s no guarantee that more attention to rubricism will cure our liturgical problems.
