 Lefebvrism and liberalism both support the New Theology and the fake premise. Lefebvrists are traditionalists  but on extra ecclesiam nulla salus (EENS) they are modernists like the liberals.

Both groups project unknown cases of the baptism  of desire and invincible ignorance as being known exceptions to Feeneyite EENS.In principle they promote a New Theology which states outside the Catholic Church there is salvation. For them there are known cases of non Catholics saved without faith and the baptism of water, in the Catholic Church. - Lionel Andrades
