Not Sufficient?
The Vatican doesn't seem overly concerned about rifts, ruptures, or recomposition as to the legions of Catholics on every continent, including numerous bishops and priests, who no longer assent to any Church teaching that does not meet with their personal approval. But the Society of St. Pius X? Now, that's another matter! Why?

(www.RemnantNewspaper.com) On March 16, 2012 an unsigned communiqué from the Vatican Press Office advised that a secret “evaluation” of Bishop Fellay’s secret response to the secret “Doctrinal Preamble,” emanating from the secret proceedings of the Vatican-SSPX conferences, has determined (in secret) that the response is “not sufficient to overcome the doctrinal problems that are at the basis of the rift between the Holy See and the aforesaid Society.” Bishop Fellay was “invited to be so kind as to clarify his position so as to heal the existing rift, as Pope Benedict XVI wished.”

We still don’t know exactly what are the “doctrinal problems” in question or what formula would suffice to “clarify” them.

That’s a secret.

We do know that on the date the communiqué was issued Bishop Fellay met with Cardinal Levada and other officials of the Congregation for the Doctrine of the Faith—in secret, of course—to discuss healing the “rift” between the Society and the Holy See, for the purpose of “avoiding an ecclesial rupture with painful and incalculable consequences...”

According to the Italian news agency AGI, during this meeting “a complete rupture was avoided by the Holy See, making it clear that Benedict XVI still expects a recomposition.” But while the rupture was avoided, the rift remains, and according to Vatican Radio “Bp. Fellay is invited to clarify his position, in order to be able to heal the existing rift, as is the desire of Pope Benedict XVI, from now until April 15.”

So, it appears there is a deadline for healing the rift in order to avoid a rupture, by providing a clarification of doctrinal problems so that there can be a recomposition.

Notice the curious avoidance of such traditional terminology as “schism,” “heresy,” “profession of faith,” and “return of the dissidents to the one true Church.”

Indeed, I have been unable to locate anywhere a Vatican statement to the effect that SSPX espouses any doctrine that is contrary to the Faith or that its individual adherents are not Catholics in good standing (as opposed to the problem of SSPX’s formal “canonical mission” status).

The word “schism” likewise no longer appears in Vatican announcements on the SSPX’s current standing.
