Plus, I love it how some sedevacantists also pretend that everything written before some magical morning in, say, 1958, or 1962 were all orthodox and then the Church groaned and somehow woke up Modernist, getting out of the wrong side of the bed that morning. Perhaps the exact moment of this transformation was on September 12, 1962 at 8:43 AM and 30 seconds.
No, the Modernists were all over the place in the 1940s and 1950s. Cushing was an open heretic, which by SV terms means he was no longer the Bishop of Boston, since manifest heresy deposes ipso facto, right? Cushing openly, publicly, and repeatedly denied EENS, calling it "nonsense", and some of the statements by Father's Jesuit superiors were even more egregious.
