PCED Confirms Officially: Society of St. Pius X within the Church, Not in Formal Schism; Catholics Commit No Sin nor Incur Any Canonical Penalty for Mass Attendance
Here's the money quotes from PCED:
Stating that the Society of St. Pius X “is not in formal schism” is to say that there has been no official declaration on the part of the Holy See that the Society of St. Pius X is in schism. Up to now, the Church has sought to show the maximum charity, courtesy and consideration to all those involved with the hope that such a declaration will not eventually be necessary.”
“The bishops of the Society of St. Pius X are excommunicated according to the prescription of canon 1382 of the Code of Canon Law which states that “A bishop who consecrates someone a bishop without pontifical mandate and the person who receives the consecration from him incur a latae sententiae excommunication reserved to the Apostolic See.” Archbishop Lefebvre was duly reminded of this before his conferral of Episcopal ordination on 30 June 1988 and the Holy Father confirmed that this penalty had been incurred in his Apostolic Letter Ecclesia Dei, #3 [cf. AAS 80 (1988) 1495-1498; English translation in L’Osservatore Romano English edition of 11 July 1988, p. 1].
“The priests of the Society of St. Pius X are validly ordained, but suspended, that is prohibited from exercising their priestly functions because they are not properly incardinated in a diocese of religious institute in full communion with the Holy See (cf. Code of Canon Law, canon 265) and also because those ordained after the schismatic Episcopal ordinations were ordained by an excommunicated bishop.
“Concretely, this means that the Masses offered by the priests of the Society of St. Pius X are valid, but illicit, i.e., contrary to Canon Law. The Sacraments of Penance and Matrimony, however, require that the priest enjoys the faculties of the diocese or has proper delegation. Since that is not the case with these priests, these sacraments are invalid. It remains true, however, that, if the faithful are genuinely ignorant that the priests of the Society of St. Pius X do not have proper faculty to absolve, the Church supplies these faculties so that the sacrament is valid (cf. Code of Canon Law, canon 144)
“While it is true that participation in the Mass at chapels of the Society of St. Pius X does not of itself constitute “formal adherence to the schism” (cf. Ecclesia Dei 5, c), such adherence can come about over a period of time as one slowly imbibes a schismatic mentality which separates itself from the teaching of the Supreme Pontiff and the entire Catholic Church. While we hope and pray for a reconciliation with the Society of St. Pius X, the Pontifical Commission “Ecclesia Dei” cannot recommend that members of the faithful frequent their chapels for the reasons which we have outlined above.
Can't get much clearer than that. This is the official position of the Church*: one can fulfill one's Sunday obligation at SSPX chapels, but their bishops are excommunicated, their priests are suspended, their masses are valid but illicit, and their sacraments of Penance and Marriage are definitively invalid.
This is the official position of the Church*
*Unless...the official position of the Church is further clarified soon, or this letter turns out to have been misrepresented, or it is simply nullified by a non-private document or statement from a higher/more competent Church authority...or, if it is made completely pointless by the lifting of the SSPX excommunications, for which I am praying and sacrificing daily.
