The Magisterium of the Catholic Church; defined the Magisterium of the Catholic Church as “the Church’s divinely appointed authority to teach the truths of religion”. In other words, Our Catholic Church Lord gave His gave the Catholic Church the authority to teach the faithful about what is expected of them, and that is what the Church has done consistently from the start.

Indeed, for according to her decree (for according to NKP_Vet Rome does not interpret) then only her version of Scripture, Tradition and history can be correct in any conflict. Which is cultic.

Thus Leo P XIII asserts:

Catholic doctrine, as authoritatively proposed by the Church, should be held as the supreme law; for, seeing that the same God is the author both of the Sacred Books and of the doctrine committed to the Church, it is clearly impossible that any teaching can by legitimate means be extracted from the former, which shall in any respect be at variance with the latter.

Hence it follows that all interpretation is foolish and false which either makes the sacred writers disagree one with another, or is opposed to the doctrine of the Church.(Providentissimus Deus; http://www.vatican.va/holy_father/leo_xiii/encyclicals/documents/hf_l-xiii_enc_18111893_providentissimus-deus_en.html)

This is consistent with recourse of Manning in the classic quote:

The doctrines of the Church then are as unmixed as the light ; and undiminished in all the perfections of truth, which like Jesus ‘ is yesterday and to-day, and the same for ever...’

And from this a fourth truth immediately follows, that the doctrines of the Church in all ages are primitive...

It was the charge of the Reformers that the Catholic doctrines were not primitive, and their pretension was to revert to antiquity. But the appeal to antiquity is both a treason and a heresy. It is a treason because it rejects the Divine voice of the Church at this hour, and a heresy because it denies that voice to be Divine...The only Divine evidence to us of what was primitive is the witness and voice of the Church at this hour. — Dr. Henry Edward Cardinal Manning, The Temporal Mission of the Holy Ghost: Or Reason and Revelation pp. 227-228.

And even the EOs find fault with Rome due to her attempts to justify her claims:

Roman Catholicism, unable to show a continuity of faith and in order to justify new doctrine, erected in the last century, a theory of “doctrinal development.”

Following the philosophical spirit of the time (and the lead of Cardinal Henry Newman), Roman Catholic theologians began to define and teach the idea that Christ only gave us an “original deposit” of faith, a “seed,” which grew and matured through the centuries. The Holy Spirit, they said, amplified the Christian Faith as the Church moved into new circumstances and acquired other needs.

Consequently, Roman Catholicism, pictures its theology as growing in stages, to higher and more clearly defined levels of knowledge. The teachings of the Fathers, as important as they are, belong to a stage or level below the theology of the Latin Middle Ages (Scholasticism), and that theology lower than the new ideas which have come after it, such as Vatican II.

All the stages are useful, all are resources; and the theologian may appeal to the Fathers, for example, but they may also be contradicted by something else, something higher or newer.
On this basis, theories such as the dogmas of “papal infallibility” and “the immaculate conception” of the Virgin Mary (about which we will say more) are justifiably presented to the Faithful as necessary to their salvation. - www.ocf.org/OrthodoxPage/reading/ortho_cath.html
