Vaticanist Andrea Tornielli's source in the Congregation for the Doctrine of the Faith provides him the following information (published in today's La Stampa - translation by Vatican Insider, corrected according to the Italian original):
[See also our previous post: The Rumor Mill]The actual and proper response of the superior of the Society of Saint Pius X, Bernard Fellay, formulated according to the requests of the Holy See, arrived at the Vatican only last week. The first reply, received by the Vatican on December 21, was not considered adequate by Vatican authorities, who asked the head of the Lefebvrians [sic] to redraft it, considering the first delivery as more of a “documentation” than a reply. Thus Bishop Fellay prepared a second text, more concise, related to the doctrinal preamble that the Congregation for the Doctrine of the Faith delivered to him last September. This second text is now being carefully examined by consultants of the Commission "Ecclesia Dei", who follow the Lefebrvian dossier, and this could require some time.
Next week, the plenary of the Congregation for the Doctrine of the Faith will meet in the palace of the Holy Office. On the agenda is a possible communication regarding relations with the Society of St. Pius X, but it is unlikely that the meeting will be decisive, because Fellay’s second response - which accepts some parts of the doctrinal preamble while questioning others - requires time to be examined. It is likely that a more accurate decision on what to do will not be made now, but in February, during a “Feria IV”, as the ordinary congregations of the former Holy Office are called. [Note: Because they take place on a Wednesday, Feria Quarta...]...
In delivering the preamble, the Vatican authorities indicated that this text was not made public because it was not yet final - that is, subject to change (though not substantive) or possible additions. From September to December, rumors of dissent within the Fraternity were spread by those who do not believe an agreement with Rome is possible. Fellay himself had spoken several times on the matter. At first, he had said that the preamble represented a great step forward. Then, after an important meeting with the heads of the districts of the Fraternity, while reiterating the importance of engaging in dialogue, he said he could not accept the preamble as it is, adding: “If Rome tells us to accept in any case, we cannot do it.” Thus Fellay sent the first response, which was not considered as such by the Vatican. And now he has sent a second one....
It is still too soon to speculate about what will be the final outcome of this dialogue, which, at this stage, goes on with distance and in writing. But no final word has yet been spoken: the Pope wants to do everything that is possible to heal the rift that was created with the Lefebvrians, and Fellay knows this well.
