Well, we've previously acknowledged the book purge at the Angelus Press, so Bowler's claim makes sense to me.
If you contact the Angelus, they may have one token copy of Fr. Dennis Fahey's works and that's just to avoid the charge that they don't carry them anymore.
Father Fahey laid out the truth about the Jєω's rebellion against the Kingship of Christ. Everything he said about the tribe had been stated previously by 60 popes.
In addition, the Angelus Press removed the important book "Peter Lovest Thou Me?" by Abbe LeRoux.
This 1986 book staked out the SSPX's position on JP II's Asssi apostasy. It was removed around 2009, so a not to offend the Pope.
Like the "reworking" and softening of +ABL's Sermons in 2004, as discovered by Ethelred, the SSPX-J has been methodically planning their reunion with newChurch.
I'm just suprised the book purge didn't hit all the Chapel bookstores uniformly, much earlier. It must have been an oversight on the part of Fr. Rostand?
