I suspect Banezian and Mr. G could both be correct:
Because the Capuchins have vacillated so much over the years, it is very possible that at various points the SSPX refused to reccomend Morgon to potential vocations (e.g., after the sermon of Fr. Jean; again with Bishop Fellay refusing to ordain their deacons in 2013 until their personal loyalty could be ascertained; again after the publication of the book in the OP of this thread, which would be in 2018, to which Mr. G refers to; etc.).
But after each of those strong stands, all Bishop Fellay ever had to do was make a threat, and the Capuchins were quickly brought into line.
There hasn't been much noise from them since this book appeared, and consequently, many in the SSPX may be of the opinion that Morgon has been once more brought into line with official SSPX policy.
Compare, however, Morgon remaining on the La Porte Latine website (i.e., for having allowed themselves to be silenced and docile to an SSPX which has no jurisdiction over it, but which is the only thing making Morgon financially viable, and who depends completely for vocations upon Menzingen for recommending young men to them), with the recent erasure of the Benedictines of Bellaigue, who no longer appear on the website.
So the way I see it, Bellaigue is OFFICIALLY banished, while Morgon (despite some intermittent flare-ups of Lefebvrian SSPXism) is still unable/unwilling to risk official rupture with the SSPX (even though they do not support the new direction at all, as the book makes abundantly clear).
PS: I have long wondered what position former French District superior, Fr. Regis de Cacqueray, holds since having become a Capuchin in Morgon several years ago: Is he a strengthening force, opposing the liberal drift of the SSPX, or, is he a weakening force within tht community, trying to keep them attached to Bishop Fellay's ralliement? I suspect I will never know the answer.
