This phrase hints that he has been conditionally consecrated by Bishop Williamson.
We would presume then that he is intending to ordain priests.
And, once more: why not go public, so people would not think that he is a bogus bishop? Why make conditional ordinations and consecrations a secret?
Yes, why all the secrecy? Why has he gone and continued to go public with his new seminary and not gone public with a conditional consecration (if he has been)?
Furthermore, why aren't more people concerned with this secrecy? If this was anyone other than Vigano, I suspect there would be.
