It was the SSPX which from its earlier years has always been squarely behind the promotion of the "1962" Roman Missal. Perhaps this was not so wise. On this blog I have never referred to the Classical Rite/Usus Antiquior/Gregorian Rite/Tridentine Rite/Extraordinary Form as the "1962 Missale Romanum." Why? Because this Bugnini-ized 1962 edition is problematic thanks to its Holy Week section.
