The books of Archbishop Marcel Lefebvre are obsolete.It's unbelievable for many traditionalists.The Archbishop made a theological mistake. The SSPX has had it wrong all these years.This is not a pleasant thing to write about.
The LG- 16-is-visible mistake is all over the Internet on traditionalist websites including that of the Society of St. Pius X (SSPX).This is the Arian- like heresy in the Catholic Church today.It is common.
Interpreting Vatican Council II with LG 16 referring to visible instead of invisible cases was easy.It is easy also for Bishop Schneider. Let's have Bishop Schneider state that all Muslims in Kazakhstan, need to convert with 'faith and baptism'(AG 7) to avoid Hell, Lumen Gentium 16( invincible ignorance) is not an exception and this is Vatican Council II for him.He does not state this in his interviews when he has been informed many times.He simply has to say that LG 16, LG 8, LG 14, UR 3, NA 2, GS 22, AG 7 etc refer to hypothetical cases only. The rest is understood.
