I never said that this was the ideal
It's not the mind of the Church for Bishops to be consecrated without the permission of Rome, but here we are.
But if bishops aren't consecrated without Papal mandate, Tradition literally perishes. No more priests, no more sacraments.
But priest CAN maintain the spirit of the Catholic priesthood in their FUNDAMENTAL ROLE of "helper to a bishop" by adhering to some religious order, placing themselves under holy obedience to SOME superior and/or bishop.
In fact, I would go so far as to say that NO priest is so isolated today, in 2026, that he can't find a faithful bishop/superior somewhere. If he can't find one, he doesn't want to. You don't have to have your superior nearby, to see him every day or every week. You could have a remote contact with him, working VERY loosely with him. At least placing your ideas under his ideas. Such priests would find their apostolate much more fruitful if they did -- it would be watered, fortified, and made fruitful with the heavenly dew of holy Obedience. Unfortunately, Trads have had to disobey Church authorities for 58+ years now, so Obedience has fallen out of fashion as a virtue to be sought after. But read the lives of the Saints, or the writings of the Fathers and Doctors of the Church. They have much to say about the necessity of Obedience.
The Bishop wears a ring, a symbol of his authority and jurisdiction. Even "sacrament dispenser" emergency bishops without actual jurisdiction keep the spirit of this, by filling the role of teacher and pastor (hence the symbolism of the crosier, it looks like a shepherd's staff).
The duty of teaching primarily falls to the Bishop, by virtue of his very office. The Bishop has to delegate much of the actual leg-work of teaching the Faithful to his helper priests under him, but the primary responsibility is still his. If the Faithful under that bishop are not taught, the bishop is the FIRST one God will blame.
If you study the history of the Church, as well as countless classic pre-Vatican II books on the priesthood, you will quickly absorb the mind of the Church on this matter.
