No, it is not permitted to attend because this is a true schismatic community and they are denying the truths that the Church has concretely established. So, the sedevacantists are true schismatic communities comparable to the Orthodox Church. There is a difference between them: the Orthodox deny the primacy of the Pope, while the sedevacantist does not deny the dogma of the primacy of the Pope; they deny that there is a head of the Church. Some believed it for 70 years, even going back 200 years. The sedevacantist believes Francis is not the Pope. It is a subjectivist concept, and it contradicts religion, common sense, and the faithful trust in God that God has always bestowed upon us, even in the worst situations in which the Church has been led by a Pope. There was always a Pope, even when there were considerable periods of vacancy in the chair of Peter, but not for a considerable period.
In this case, the sedevacantist denies, in practice, the reality of the primacy of the Pope, which is an essential part of our Catholic faith. They are in some ways similar to the Orthodox communities at this point, which both deny the practical, concrete aspect of the dogma of the papacy. Therefore, we cannot go to the sedevacantist Mass in this case because we truly believe in the fullness of the revealed truth of the primacy of the Pope. It is opposed to the church's visibility and is moving closer to Orthodox teachings. According to them, the head of the church is invisible; it is only in Christ. This is truly against the fundamental structure that God gave the Church: the visibility of the head of the Church—the Pope, the bishops, and the priests.
There is a difference for the Society of Saint Pius X in believing in the fullness of the primacy of the Pope because the society accepts the Pope and names and prays for him in the Mass. Their problem is that they do not obey his orders, but this is another canonical aspect of external disobedience, which they have good reason to believe given the church's enormous, extraordinary crisis. Unfortunately, the Pope helped and promoted harmful things in the church, especially in the liturgy, which justifies their disobedience to the Pope. I think it is important that the Society of Saint Pius X believed in the primacy of the See of St. Peter.
It is truly necessary to obey the primacy of the Pope, for it is within the fullness of the Catholic Church, especially when the Pope speaks about doctrine, which is the doctrine of Christ. In the case of the Society of Pius X, obedience is limited to canonical submission. This is the difference between the Society of Pius X and the sedevacantist communities.
