Not today, in the absence of a true Pope, whom alone this Authority would derive from.
Let me ask, where is the formal authority existing (in practicality) for the R&R camp today anyway?
Authority is an attribute of the Church primarily and only secondarily and accidentally an attribute of the pope. Those who make the pope the rule of faith have a problem when he is a heretic with the exercise of authority. Those who make dogma the rule of faith can deal with the corruption of authority.
Sedeprivationists destroy the papal office by dissolving the unity of its form and matter. Sedevacantists destroy the papal office by permanently getting rid of it. R&R recognizes the authority but its obedience is directed by the virtue of Religion. For this, like the man born blind, we have been excommunicated from the Novus Ordo. No surprise here. So you can argue about the “practicality” of R&R but it does not lead to intellectual vacuum or doctrinal and moral dead end that is incompatible with revealed truth.
