Nothing could be further from the truth. You have missed my point entirely. I think Mons. Perle's letter is a weak defense of your position. I would argue that the SSPX's existence (if your posts are any kind of indicator) is no longer strictly dedicated to devotion. In contrast, the FSSP is. The FSSP exists to provide the sacraments in the traditional rites without all the destructive rhetoric.
Nor do I need you to advise me where I should go to attend Mass on Sundays.
It is Mons. Perle that is advising you, not me, but you interpret his advisement in exactly the opposite meaning of his intent. That is all I am pointing out. That is why I think that you are mistaken when citing Mons. Perle's letter to justify your position.
