Do you believe that papal infallibility is a theological issue or a practical, administrative issue? The more I think about this question, it appears to be practical rather than theological. The same applies to the authority of bishops in an ecumenical council. The Church’s bishops didn’t gain an additional, intrinsic power to teach the Faith in the 4th century when ecumenical councils commenced. Rather, they used their common power to teach orthodoxy and condemn heresy in a new, more practical venue, thus giving their common episcopal charism a more coherent voice.
The same appears to apply to the Pope and his “extraordinary magisterium” in Catholicism. According to Catholicism, the Pope, insofar as he remains a faithful bishop can teach orthodoxy and condemn heresy at any time, gained a more coherent form to do this in 1871. However, like that of the ecumenical council, this new practical avenue to teach the Faith doesn’t add to the ability of the Pope to condemn heresy, which every bishop intrinsically possesses when he chooses to teach Tradition. It only gives this power a more practical and, according to Catholicism, more successful, application in the maintenance of Church order.
Therefore, there can be no more theological objections to the development of the papal “ex cathedra” statement than there can be to the development of the ecumenical council, for neither deal with an increase of intrinsic doctrinal authority of said bishop/bishops, as these new mechanisms would only be practical developments that give greater voice to the common episcopal authority (which is given fully to many bishops as well as each individual bishop) to teach the Faith.
