"This new idea of an "Authentic Magisterium" opposed to the ordinary and universal magisterium has already been adequately refuted by Mr. John Lane.
Both John Lane and John Daly have erred on this point. They think that the ordinary and universal magisterium pertains to extension merely in place, but not in time, i.e. tradition. Therefore they misunderstand the nature of said magisterium, implicitly reducing all its acts to an infallible exercise of authority, either ordinarily (based upon their misunderstanding) or extraordinarily. But the ordinary and universal magisterium pertains to a dual extension of space, i.e. the moral body of bishops and time, an ascertainable doctrinal tradition.
But I have argued all along that the post-conciliar Popes have tacitly renounced their authority only to engage in dialogue and invitations, thus also abandoning any substantial help from the Holy Ghost. And if you'll note, the rare moments when it actually has been exercised, there was nothing intrinsically objectionable. The bishops also must desire to be traditional in order for them to partake of their special teaching function. The lust for novelty has always been looked upon with abhorrence precisely because ecclesiastical tradition is a sure guide and manifestation of Divine Wisdom. But what happens when those who hold the office are themselves disobedient to tradition and unfaithful to their most basic duties? A crisis of faith results! The exercise of the magisterium is not a mechanical action, these men possess the free will to either fulfill their duties or not. They can hold the office but refuse to cooperate with the grace and duty of the office itself.
When discussing the essence of a doctrine, it is assumed that all else is equal and objectively proper. It is quite otherwise in a concrete situation where an evil arises. An example would be the teaching on the Sacrament of Baptism. When the magisterium taught this doctrine, it was presumed to be within the context of the Catholic Church. Now you can't say precisely the same thing when the context of its administration has changed, i.e. when administered in an heretical sect. The circuмstances have changed and therefore different principles come into play. But Vatican II takes the opposite method. When they discuss Baptism, they speak of it precisely in the same sense whether it has been administered within or without the fold. This is a grevious error for the circuмstance introduces an impediment. By glossing over this fact, it makes it appear that Baptism can be indiscriminately administered by anyone at anytime with the same efficacy and moral rectitude that accompanies its administration within the Catholic Church.
And this
same method some traditional Catholics take vis-a-vis the teaching on the magisterium. They cannot distinquish between a principle and a concrete fact which is not always commensurate with the exigencies of the doctrine. Thus, due to a misunderstanding of the magisterium, people are tempted to renounce the entire hierarchy or enter the novus ordo.
