+Williamson only mentioned Fr. Bouchacourt, but he did say explicitly there would be TWO new bishops.
Who will the second be?
It would only be speculation, and speculation is far less useful or valuable than cold hard facts.
However, here is a fact for you:
Current Superior General: Fr. David Pagliarani
First Assistant: Bishop de Galarreta
Second Assistant: Fr. (soon Bishop?) Bouchacourt
See the problem? Not one, but BOTH assistants will be bishops, while the head of the organization will be a "mere" priest.
Also, the SSPX has experienced leadership by a Bishop since 1994, except for the past few months.
Interesting...
