A response that is far too timid in my opinion. I understand why, out of fear of the repercussions from the vatican or local bishops for being to bold. I much prefer the courageous response of Father Pagliariani (the superior general of the SSPX). https://fsspx.news/en/news-events/news/letter-father-pagliarani-about-motu-proprio-%E2%80%9Ctraditionis-custodes%E2%80%9D-67623
Pagliarani that is. The only thing harder than spelling his name is pronouncing it!
