That union of the Bishops with the Pope is absolute, necessary. No power was given the Apostles independently of Peter A. Bishop who separates from Peter would lose his authority in the Church. This union is what Christ willed. Peter has over the episcopate a true and supreme authority. The entire body of the Bishops has no authority without the Pope.
Popes have the authority to approve or to annul councils.
On the other hand, the submission of the faithful to two authorities, papal and episcopal, does not imply confusion in the government of the Church, for the two authorities are not on the same level. This doctrine will help Catholics to adhere to their Bishops and to the Pope. One cannot have Christ as his father who does not have the Church for his mother.
