Validity of sede Bishops

[Historian]

Another answer is that "yes" the Thuc consecrations are valid.  This has been studied over and over again.  In fact, they should be considered more valid than any of Modernist bishops that purport to have some kind of authority in the local diocese.  It is actually the Modernists that need to submit to the Church and actually accept the Catholic faith before they can even be considered to have any authority.

How many of these modernists are "ordaining" female pop singers?

The Church is guided by the Holy Ghost, not by temporal concerns.
