Here's my answer written on July 16th.
Dear Fr B,
It is with clear insight as to what I'm doing that I now wish to withdraw my membership from St Mary's. For many weeks now I have known that I cannot ever go back to the Novus Ordo, no matter how reverently celebrated, because the Mass of the Ages does something to a soul that the Novus Ordo never could, for me at least. I cannot remember the last time I teared up at a Novus Ordo Mass, but it happens almost every time I'm at St Thomas More. The beauty and joy of it all is ...well...otherworldly and is, frankly, what I converted for all those years ago.
With Bergoglio's Motu Proprio today against the Mass of All Time I know now is the time I must make this decision. I can no longer be a member of both St Mary of the Lakes and St Thomas More. If Bergoglio excommunicates the SSPX then I shall die excommunicated. So be it. But then that clearly brings into question the validity of such an act by a Marxist globalist who people think is the pope when in fact he possibly isn't. (Just FYI - the SSPX thinks he is and prays for him in every Mass, but I don't necessarily think that way.)
I want to thank you for all your kindness to me over the past several years. I never felt anything but pastoral love from you and your presence at St Mary's and for that I sincerely thank you.
May God be with you,
