After looking through the Italian text which I obtained, I can share a few other things in my fast translation. I read German pretty well, but I translate Italian faster, and Italian was clearly the original language.
Pay close attention to his comments about resistance to the older form of Mass and how that resistance must be overcome. It must be overcome, of course, because it is wrong.
Q: The Pope asked for “charity and pastoral prudence” for traditionalist faithful. Now, at the Pontifical Commission “Ecclesia Dei”, you are a kind of fire department for cases in which don’t go that way. Where do you find resistance? What what motivations?
The expression “vigilare” translates Greek “episcopein”. Vigilance is the primary competence of the bishop. In this sense the Pontifical Commission “Ecclesia Dei” exercises the office of observation and vigilance over the application of the Motu Proprio. There still now exist certainly some prejudices and resistance against the Mass in the antiquior rite, either from ideological motives or in part because the request for the Mass in the Extraordinary Form is considered an expression of contrast and opposition to the liturgical reform desired by the Second Vatican council. It is clearly necessary to overcome and challenge these still widespread prejudices and to recover, above all, the unity of the history of the liturgy, the unity of the lex orandi as an expression of the unity of the lex credendi, even in the specificity of the liturgical forms of the one Roman Rite.
Q: A clarification: Which objections move a parish priest/pastor or bishop who has no respect for the old Mass to refuse requests?
There are prelates who above all see the risk of a nostalgia or an aesthetic sort, purely ornamental, formalistic, in the request for the old rite. This, however – I don’t want to exclude that in some cases this can also be true – indicates, in just a general way, a kind of bias. Because the antiquior rite has on the other hand a profound richness that must be non only respected, but rediscovered from the vantage point precisely of the liturgy as it is also celebrated today. And so these biases, these oppositions, have to be overcome through a change of a forma mentis. A more adequate liturgical formation is needed.
The Motu Proprio does not speak of the formation of priests who want to learn the say the Mass according to the old books. According to some this is a lacuna (gap), inasmuch as it requires not a little training to celebrate the old liturgy. To this point, what can you advise to priests who are interested?
Certainly the problem of the priest who is suited (idoneo) for the celebration of the previous Rite is of great importance and urgency. I must say that often the motive for which individual Ordinaries have problems in responding favorable to the request of a stable group of faithful to assist at Mass in the antiquior rite is precisely the lack of priests suited to its celebration. It is necessary, therefore, that the faithful making the request, have come understanding and great patience. I am of the opinion that in seminaries there should be offered to seminarians the possibility of learning adequately to cerebrate also the Extraordinary Form. I am not speaking of an obligation, but of the possibility. Where it is possible, one could make use for this preparation of priests of religious institutes which are under the jurisdiction of Ecclesia Dei and which follow the traditional liturgical discipline. However, what seems to be essential is liturgical and theological formation for which it is necessary to reject radically the idea that there exists a pre-Conciliar liturgy in opposition to a post-Conciliar liturgy. There is a growth and deepening in the history of the faith and of the Church’s liturgy, but also in continuity and in substantial unity, that cannnot and must never be lost or diminished. This is the line, the plan that must be follow also in view of a better preparation of clergy.
Will the Holy Father one day celebrate a great Mass in the Extraordinary Form?
I think you are asking the the wrong person!
There is more, and in time to come I may get to that as well.
