I don't trust Schneider at all. This quote from his book:
From an Amazon review:
From Pg 149 "We also discussed their (SSPX) assertion that the new Mass is "evil" or "bad." I told my interlocutors from the SSPX: "You should not speak in this manner." I told them that I am also not happy with the new Mass. I suggested that they use the expression "the new Mass has defects but is not an evil." I also said to them: "When you say that the new Mass is evil you are accusing me of committing an evil, a sin, because I, too, celebrate the new Mass."
Schneider also does not think that VII should be repudiated.
Not good enough......
