Whilst the brave father naturally opposes the Neo-SSPX' neo-liberalism and intended deal with Newrome, he never publicly criticised his superiors including Bp Fellay, in order not to scandalise the faithful,...
But would it not be better to scandalize the faithful for the sake of the Faith?
Well, if Mr X publicly claims that 2+2=8, we lovers of Truth can publicly a) insist on the fact that 2+2=4, and b) say that Mr X is terribly wrong. Ideally we would do a) and b), but depending on the circuмstances we can still uphold the truth by doing a) only, for a certain amount of time. At one point we should proceed to also do b), I'll give you that.
As I mentioned, the good Fr Sauer always said publicly that Newrome and the Newpope must convert first before we (the SSPX and us laypeople) can make a deal with Rome (which then will be simple and straightforward).
So, the good father protected the Faith and he also scandalised those dreamers (for the sake of the Faith) who wrongly thought we could join Newrome now.
Although this was not a direct criticism of Bp Fellay, it was of course an indirect one, because the latter wants to join Newrome. Menzingen got this indirect criticism and this is probably why the good father now had to leave the Neo-SSPX.
Today the brave Fr Sauer has all the liberty to preach not only that 2+2=4 (like he's always been doing) but also to openly naming those claiming that 2+2=8. I think after some time of getting used to his very new situation, we're probably going to hear more from him.
May God bless Fr Frank Sauer and all other orthodox bishops, priests and clerics.
P.S. Thanks to some brave souls from Germany I could get a few MP3 recordings of Fr Sauer sermons in German language. The MP3 audio quality is bad, but the content is excellent. Readers interested in these files could please PM me.
