At the Society of St.Pius X (SSPX) chapels and centers the Catechism of Pope Pius X is sold which they interpret with the False Premise, so 29Q( invincible ignorance) contradicts 24Q and 27Q( outside the Church there is no salvation).

 At  the Society of St.Pius X (SSPX) chapels and centers the Catechism of Pope Pius X is sold which they interpret with the False Premise, so 29Q( invincible ignorance) contradicts 24Q and 27Q( outside the Church there is no salvation).

So when the liberal Archbishop Augustine di Noia , Adjunct Secretary of the Congregation for the Doctrine of the Faith, Vatican asked Brother Andre Marie micm, Prior at the St. Benedict Center, New Hampshire, to interpret the Catechism of the Catholic Church ( 847-848-invincible ignorance) as an exception for Feeneyite extra ecclesiam nulla salus, no one from the SSPX pointed out the error. 

Since this is how they also interpret the Catechisms, old and new.

The SSPX Bishops too would interpret the Catechism of the Catholic Church with the same False Premise i.e the baptism of desire and being saved in invincible ignorance, are visible cases in the present times, of salvation outside the Catholic Church.With the False Premise the SSPX is interpreting Magisterial Documents like the liberal Massimo Faggioli. It's an either-or.Massimo Faggiolu says on Twitter that we have to choose the theology of the Syllabus of Errors or Vatican Council II as interpreted by the popes and him ( with the False Premise). Bishop Roland Minnerath in his writings says the same.
