“But by far, the most vital change was the insertion of the words “as of faith,” and “as contrary to faith” (tamquam de fide, tamquam fidei contrarium). These words limited the infallibility to definitions de Fide and condemnations under the censure of “heresy.” Hereby was involved a theological question long debated in the schools. The Catechism definition of “Faith” runs: “Faith is a supernatural gift of God – a grace – which enables us to believe without doubting whatever God has revealed.” God the Revealer is the motive of Faith, and only what He has revealed, only what is in “the depositum,” be it contained in Scripture or in Tradition, explicitly or at least implicitly, can be the object of divine Faith. We have heard Bilio formulate the theological difficulty (in Senestrey’s Diary): this is all that could be said to be of Catholic Faith; and therefore the definition of Papal infallibility could not be extended wider than the certain sphere of the Church’s infallibility. He himself held the ordinary opinion of theologians, that the infallibility of the Church, does extend beyond the limits of what is of divine Faith as revealed by God; that such things as the canonization of saints, the approbation of religious orders, condemnations of propositions under censures short of “heresy,” and dogmatic facts intimately bound up with the safeguarding of revealed truth, do fall within the sphere of the Church’s infallibility, and are to be accepted with interior assent, not by divine Faith, because they are not revealed truths, but by what is called “ecclesiastical faith” in the teaching authority of the Church. This is the common teaching of theologians, but it has never been defined, and discussions are still current over the whole question…As will be seen, the Vatican Council deliberately left this question untouched, and defined the papal infallibility in such a way as to leave these theological questions undecided.”
