From the blog The Eponymous Flower, Seminarians of Paris Get to Know Immemorial Mass of All Ages
So what? They offer the TLM with the New Ecclesiology. They interpret Vatican Council II with the false premise instead of without it.They interpret extra ecclesiam nulla salus with Cushingism instead of traditional Feeneyism.It's the same at the Novus Ordo or Byzantine Rite Mass.
They proclaim the Catholic faith with possibilities of salvation outside the Church, speculative cases, as being practical exceptions to traditional EENS. This is the bad religious formation also at the SSPX seminaries.
They do not proclaim the Faith knowing that LG 8, LG 14, LG 16, UR 3, NA 2 ,Gs 22 etc refer to hypothetical cases and not real people. They do not proclaim the Faith knowing that EENS is the ordinary means of salvation.
So they only follow the rubrics of the TLM while their theology and ecclesiology is Novus Ordo.So they are recognised by the present Leftist Magisterium- Lionel Andrades
