Thanks to a French Canadian gentleman of the Resistance, here is a translated into English extract of a conference given by the saintly Archbishop Marcel Lefebvre on April 11, 1990 in Econe, Switzerland. This extract concerns the liturgical reforms attributed to Pope John XXIII. It is clear from this conference that a true follower of Archbishop Lefebvre cannot reject the 1962 Missal and Breviary.
The audio extract (in French) of the conference regarding this subject is provided below, courtesy of the same French Canadian gentlemen.
