Haven't you read about +Fellay's "grace of state"? That was the topic du jour last spring. But you have asked one of the million dollar questions, Matto. The SSPX brass don't seem to be making that interesting claim now.

Speaking of +Fellay's "grace of state", I have wondered how he was "deceived" by Pope Benedict XVI while he possesses this gift.
That would have been the "grace-hiatus of state," or the "gap-in-grace
of state," or the "grace of state-on-leave," or the "grease of state" (you
know, like Greased Lightening, which was a pig), or the "grays of state,"
or, the "gummy bears of state," or the "great-Ace of state," or the
"grade-ness of state," or the "graze-us-state."
I'm sure Max Krah can come up with something. If he can't then he
should just ask his puppet-string master (whoever that might be today).
