How can the Holy Spirit teach error,Pope Francis ?

Pope Francis said that the Second Vatican Council “was a beautiful work of the Holy Spirit,” according to a Vatican Radio report recently.

 

According to whom?

Did the Holy Spirit teach that Lumen Gentium 16 refers to visible- in- the- flesh cases of persons saved in invincible ignorance ?

Or did the Holy Spirit mean that there can be persons saved in invincible ignorance and these cases would not be known to us ?

Did the Holy Spirit say that Lumen Gentium 16 is an exception to the dogma extra ecclesiam nulla salus as is widely reported in the media over so many years ?

Or did the Holy Spirit mean that Lumen Gentium 16 is irrelevant to the dogma extra ecclesiam nulla salus and to Ad Gentes 7 which says all need 'faith and baptism' for salvation ?

According to EWTN,Catholic Culture, Catholic Answers, Catholics United for the Faith, Ecclesia Dei's Vice President, the Vatican Curia, Jesuits and popes including Pope Francis-  LG 16 is visible and so is a break with the past.This is irrational.
