Here is a nice brick by brick story picked up from NLM:
Recently there was a meeting of French faithful attached to the usus antiquior, the rencontre pour l’Unité Catholique (Meeting for Catholic Unity), in Versailles, France. In the course of the meeting, Fr. Laurent Spriet of the Association Totus Tuus made an important announcement.
Fr. Spriet announced, that Cardinal Barbarin will open next year in Lyon a "bi-formalist" seminary, i.e. a seminary dedicated to both forms of the Roman Rite, which will be both taught and celebrated there. This is the first diocese in France after that of Toulon which offers this possibility to its seminarians. Cardinal Barbarin’s project will even go further than that of Toulon: not only will the seminarians have the opportunity to be formed according to the extraordinary form, Mass according to the usus antiquior will be celebrated every day in the seminary, open to all seminarians, including those of the ordinary form.
What I think we have to call into question is the reference to speaking about "ordinary or extraordinary form seminarians".
I don’t think priests should be ordained for books.
I praise, laud and applaud the initiative to bring all the men together for integrated formation. That is very important. However, I think that all men should be trained equally in both forms so that, in their ministry, they have all the tools they will need for the future as Roman Catholic priests.
