There is little connection between Latin literacy and the desire to celebrate the EF. Several of the Latinists used by the Holy See to translate official documents have, shall we say, no love of the traditional rites and certainly have no intention to celebrate them. It would seem in some seminaries, where dead languages are still taught, Latin instructors have been chosen partially because they do not celebrate using a 1962 missal. (Any earlier edition, of course, would be quite 'beyond the pale'). But isn't all of this actually a smokescreen for a greater malaise- that of a general unwillingness to participate in the full tradition of the Church and all that demands of the individual? So what could be the fears?
(1) I haven't got the Latin to celebrate the rites.
Not a new problem. Before Vatican II quite a few clergy had been dispensed from the office. In the questionnaires before the Council one notable Archbishop suggested a vernacular office for his clergy. Fear not- help is available. There are enough courses, on line, residential, and otherwise to bring even the most average up to basic competence.
(2) I haven't got the time to learn the ceremonial.
Again there are numerous user friendly guides which take you through step by step. There are priests who will privately help in this direction. A first 'practical' lesson often is in another priest's study using what ever happens to be at hand to indicate the chalice and paten.
(3) It would divide the faithful.
The faithful are divided already. If you've got a vocal group of the faithful opposing the innovation of a single traditional Mass into the parish schedule they're in serious need of personal catechesis.
(4) If I do I won't be 'preferred'.
One commenter emphasised this problem recently and unfortunately it seems to be true. But then again, what is more important in the long term? Best to walk carefully here. The abuse of false allegiance and obedience is a factor in clerical life.
(5) I've got enough to do as it is.
This can be understood as the load on parish priests these days is probably greater than any other time in history. Even where there has been wise employment of people for administrative tasks and catechetical and other duties the supervision of all this remains the responsibility of the pastor. Perhaps this could be added to the list of things for continuing diocesan formation of the clergy instead of the regular seminars on Fairtrade, the Enemagram, or whatever the fad of the moment is.
