Irrelevant and provocative as well as admittedly "wry and derisive." Rather than offering reactions or being positive in terms of Bishop Fellay's fine sermon which, BTW, deserves respect and comment, you choose to be "derisive."
Yeah, I get it. Make it personal and contentious rather than charitable and responsive. God bless Bishop Fellay and all the SSPX priests who have devoted their lives to Him.
We'll soon see as to steps taken in this pontificate as to the alleged excoms and you can then eat your words on that issue. Until then, in His charity, hope, and Faith...
The first option is Sedevacantism. One can only for so long maintain the double-mindedness in, supposedly, acknowledging the Pope's Universal Jurisdiction while constantly repudiating it in practice
The second option is accepting the sspx Pope. Williamson has written about this previously. That is the end this schism is headed towards. They will have their own conclave and elect a Pope. He will be acclaiamed a Traditional Pope who represents eternal Rome...blah, blah, blah.
The third option is not within the reslm of possibility. Fellay is not about to admit all he has done and said for the past 20 years has been indefensible. He is clearly insane and he does not have the humility to either admit his heresies or beg forgiveness for them and retreat from the stage.
Good Luck with all of that.
