An clear endorsement of the R&R position:
The question of the pope does not arise when the council taught error, because it was a pastoral council in which the popes deliberately withheld infallibility.
This has been the R&R position from the beginning which one will find laid out in the early works of Michael Davies and Lefebvre all the way until the present in the works of +Williamson.
Sedes won’t/don’t like that, of course, and will now begin opposing today the Bishop they had hopes for and praised yesterday.
But maybe they can make the same act of humility Vigano is calling on the conciliarists to make, and acknowledge their errors, and in this way fall into line to strengthen the traditional counterrevolution.
