Perhaps you could put a comment on their blog (at the link above) encouraging them and promising your prayers.
I see also on their blog that their seminarians have had to be withdrawn from an SSPX seminary over this question.
one of the three Brothers was called to the Rector’s office. During the course of the interview the Rector suggested that possibly the only way to stop me from carrying out negotiations with Rome was by threatening to start up a breakaway community. This suggestion was also repeated at another time to all three Brothers.Well, the SSPX position seems pretty clear. How sad.
I later received an email from the Society saying that if we made an agreement with Rome, our seminarians would not be welcome in any SSPX seminary.
