My post yesterday should make it clear that the issues surrounding the SSPX kerfuffle with the Holy Father is not easy to figure out. Bishop Athanasius Schneider, a deeply devout Pastor of souls, made some comments last week on the very same subject and I want to include one quote here from him for your edification.
In fact, through its tireless insistence on clarity in doctrine and liturgy, the SSPX renders a great service to the entire Church — a service of historical value. If the Holy See were to take this stance of the SSPX seriously — and, moreover, acknowledge the objective ambiguities in certain statements of the Second Vatican Council and in the rite of the New Mass — it would mark the beginning of the end for the modernist project within the Church, which in fact began more than a hundred years ago.
