On the question of whether the SSPX is schismatic or not (some say yes – that would be the late Pope) I found this on the SSPX website. It concerns whether or not people who follow the priests of the SSPX can also attend Masses under the "indult", that is, with the approval of the Catholic Church’s diocesan bishops. I find this really interesting. Emphasis and comments are mine.
UPDATE: See the useful comment below by "Somerset ’76" which has a possible explanation of what follows.
CAN WE ATTEND THEIR [THEIR!!!] MASSES?
If we have to agree to the doctrinal and juridical [This might mean that the Pope has no right/power/authority to make changes to the Mass. This might otherwise mean also that you don't fulfill your obligation by attending the Novus Ordo.] value of the Novus Ordo Missae, then NO, for we cannot do evil that good may ensue [So, attending a Novus Ordo Mass is "evil"?].
This condition may not be presented explicitly, but by implication, such as:
By a priest who celebrates the Novus Ordo Missae on other days of the week or at other times [Apparently a priest has to be ordained not just for people but for a book. Talk about being "people of the book", huh?],
using Hosts consecrated at a Novus Ordo Missae [This would mean that those hosts would not be validly consecrated because they were consecrated at a Novus Ordo Mass?],
or with communion in the hand [If the hosts are not consecrated validly anyway, what difference would it make? Otherwise, if they are validly consecrated do they stop being Jesus Truly Present if they touch a hand? I do not quibble in the least about the lack of reverence for that reality, however.];
new lectionaries, Mass facing the people, etc., [So, if Pope Benedict celebrated the "Tridentine" Mass at the High Altar of St. Peter's Basilica, the SSPXers could not attend?]
by a priest who was ordained in the New Rite, [Does that mean that I am not validly ordained as far as they are concerned?]
by sermons that are modernist in inspiration (much to be feared if the celebrant habitually says the Novus Ordo Missae); or [This is strange. "modernist in inspiration" ... how to decide? I guess this is like the phrase of the Supreme Court justice who knew pornography when he saw it. "I can't define modernist in inspiration but I know it when I hear it."]
by offering only the revised forms of the other sacraments, e.g., penance. [Okay... so if I absolve a penitent ... ironic ... since SSPX priests DON'T HAVE FACULTIES TO ABSOLVE penitents unless they are DYING - so if I absolve a penitent in using the NEW form of absolution that means that the MASS I say is defective?]
This brings up the whole context of the Indult Mass. It is:
A ploy [MWUHA-HA HAAAAHHA... Boy! are we cunning.] to keep people away from the Society of Saint Pius X (for many Bishops allow it only where there is a Society of Saint Pius X Mass center),
intended only for those who feel attached to the traditional Latin Mass [If it is so great in itself isn't that enough of a reason?] but nevertheless accept the doctrinal rectitude and juridical right of the Novus Ordo Missae, Vatican II, and all official orientations corresponding to these. [So, when Pope Benedict derestricts the older form of Mass, does it sound like that move is going to be enough?]
Therefore, attending it because of the priest’s words or fellow Mass-goers’ pressure, or because of the need to pander to the local Bishop just to have it, [Heaven forbid anyone should exercise any charitable DIPLOMACY rather than simply issue demands to a successor of the apostles or to the alter Christus, but oh.. that's right... we might not really be ordained properly. Why show us respect?] inevitably pushes one to keep quiet on “divisive issues” and, distance oneself from those who do not keep quiet i.e., it pushes one to join the ranks of those who are destroying the church. [MWUHA-HA HAAAAHHA... Boy! are we cunning.] This one cannot do.
The Indult Mass, therefore, is not for traditional Catholics.
I think we ought to apply the duck argument.
