Of particular importance for this is the last section of the video that begins at 47:54.
+Fellay is asked whether the Society will consecrate more bishops, and he responds that they will follow the same procedure as in 1988 (ie., Lefebvre went to Rome to ask them).
The problem there is that once Lefebvre realized Rome was negotiating in bad faith, his action was taken independent of Rome.
By ignoring that, +Fellay is effectively saying that the Society will seek permission from a Rome hostile to Tradition, such that, were bishops granted, they would certainly be of a stripe inimical to Tradition (whether they come ad extra (Huonder) or ad infra (du Chalard, Celier, Simoulin, etc).
That type of inexplicable posture is what has me wondering if the SSPX hasn’t already received a “recognition of tolerance ad tempus” (ie., a probationary approval, contingent upon good behavior), which they fear to lose.
