46. "We teach, . . . We declare that the Roman Church by the Providence of God holds the primacy of ordinary power over all others, and that this power of jurisdiction of the Roman Pontiff, which is truly episcopal, is immediate. Toward it, the pastors and the faithful of whatever rite and dignity, both individually and collectively, are bound by the duty of hierarchical subordination and true obedience, not only in matters which pertain to faith and morals, but also in those which concern the discipline and government of the Church spread throughout the whole world, in such a way that once the unity of communion and the profession of the same Faith has been preserved with the Roman Pontiff, there is one flock of the Church of Christ under one supreme shepherd. This is the teaching of the Catholic truth from which no one can depart without loss of faith and salvation."¹⁷
