To add another one.
Like to like: conciliar SSPX
And Fr. Chazal's new one: XSPX ExSPX
+W spells it ExSPX, to make it unmistakable.
I didn't explain this very well. It seems that "XSPX" might not be so
good because most readers would likely think that it was just a
typo or some kind of mistake like "FSSPX" is the French version, so
maybe someone got an extra X in there for whatever reason.
But if you make it upper case E and lower case x it suddenly is
outside the likely confines of an innocent mistake, and it looks
really deliberate -- mostly because it IS deliberate.
If it were ExSSPX, it would be mistaken for any of the expelled
priests who are no longer (so they say) in the Society. We are
not talking about those guys. It is the CHANGED Society itself
that we're referring to, the ExSPX. The "Ex" replaces "S" for
Society, that is, it is
a replaced Society. It takes a kind of genius to make such profundity out of one or
two letters of text.
