To allege that the SSPX is heretical requires one of two things, either a stretch of the definition of heretic or a decree by the only person who has the authority to call anyone a heretic, the Bishop of Rome.
Having said that, we must be very cautious with the content of their statement. There are several serious problems in it.
- It is an attack on the popes of recent years, even if it does not name them.
- The SSPX demands the right to correct and denounce anyone whom they perceive to be in conflict with truth. But this would elevate the SSPX to a second Magisterium and would give the SSPX the same authority as the CDF, which is the official organism through which the Holy See corrects errors and defends truth, along with the bishops of the world.
- The SSPX has no canonical place in the Church. Therefore, whatever statement the SSPX makes about the Church is only an opinion. It carries no authority. Any faithful Catholic who credits it with any authority is confusing the issue. Organizations and individuals can have opinions, but only those with a canonical place in the Church can make an authoritative teaching statement.
- There are statements in the document that are heresy and some that border on heresy. However, we must distinguish between a statement that is a heresy and a person who is a heretic. Many faithful Catholics make heretical statements all the time. Either they don’t know their faith or they have a very strong opinion on some subject and they are convinced that their opinion is correct. I believe that the situation in the SSPX is the latter.
There are precautions that everyone who attends an SSPX chapel must take. The first is to keep in mind that throughout the history of the Church, the heresies and schisms have all come from the right, not the left. Liberal left wing ideas are never well organized nor convincing enough. The eventually collapse. Right wing extremist ideas often sound very logical; therefore, they are convincing. We have to keep that precaution in mind.
There is a danger here that the bishops of the SSPX will ordain other bishops to succeed them. If they do this, these bishops will excommunicate themselves, again. My concern is that if they do so, will they break with Rome. I don’t know. But it is possible. It is also possible for Rome to jettison the SSPX from the Church, if the leadership makes such a choice. Let’s pray that they do not ordain another bishop.
There is a contradiction in their thinking. They allege that the papacy has lost authority. However, they refer to an archbishop who died outside of the Church as “venerable”. You can’t have it both ways. Either the pope has the last word and Archbishop Lefebvre was outside of the Church or the pope does not have the authority to sustain the excommunication.
Either the pope has the authority to interpret and apply canon law at his discretion or he does not.
You can’t have a papacy with absolute and unquestioning legal and moral authority with restrictions that you impose on it, such as using the law in a way that the pope does not use it.
These are real problem areas.
The best we can do is to pray for a resolution to this nightmare.
