Interested in attention to precision, can you really conflate a denial of proclaiming dogma (which is specifically used in Paul VI’s quote) with a denial of teaching infallibly at all? Denying that Vatican II proclaimed any new dogma (which is the way Cdl. Ratzinger put it) would not rule out infallibly describing dogmas already proclaimed or even infallibly pronouncing doctrines to be held by all the faithful.
I was also wondering, since CathSem posted along the lines of a hierarchy of belief, whether the characterization of a hierarchy existed previously in the Tradition, and, if it did, whether it used the same categories.
As to your first paragraph: Certainly some parts of V2’s teaching are infallible inasmuch as they repeat teaching that was previously decreed in an infallible manner. For example,
Dei Verbum 10 says “Sacred Tradition and Sacred Scripture form one sacred deposit of the Word of God, committed to the Church …” This statement is a reaffirmation of what was decreed infallibly at Trent and Vatican I (and perhaps elsewhere). To dissent from such a teaching would be heresy in the proper sense. However, there are no new infallible dogmas proclaimed at V2. Therefore, the best statement I can make on the status of V2 teachings is that those parts which are not repeating a previously defined dogma of infallible doctrine fall into the third category of magisterial statements which are authoritative and requiring the “religious submission of the will and intellect” though not infallible. As a result, if one were to dismiss Vatican II and make claims against the legitimacy of its teachings, he would not be a heretic (unless they also denied something infallibly proclaimed earlier) in the proper sense, but would be at risk of serious error. Furthermore, such a person would be at least somewhat culpable for their error because they failed to trust the shepherds that God put over the Church. It is possible though, that one using his best judgment and reason cannot reconcile a V2 teaching with previous Church teaching. Despite wanting to believe what the magisterium is saying, that person is unable to mentally assent. Such a person runs the risk of being wrong, but perhaps is not culpable because he is attempting to be faithful and obey the Church, but is unable to do so. Such an attitude is in marked contrast with those who publicly oppose the magisterium and flaunt their disobedience and dissent from Rome. (I speak of both liberal dissent and conservative dissent; I’m not picking on anyone.)
In response to your second paragraph, it seems to be a little yes and a little no. These specific categories were clarification issued by JP2 after 30 or so years of confusion in an attempt to reexplain what
Lumen Gentium professed regarding categories of teaching. The first category of dogmas with their denial being heresy dates back to the first dogmatic decision on the Trinity at the Council of Nicaea in 325. Lower teachings requiring obedience (essentially the third category) are also seen in various canons of ecumenical councils, local councils, papal bulls, and the like which are authoritative but contain no anathemas or other “definitive language” (e.g. that used by JP2 when ruling out the possibility of women’s priestly ordination). The second category is the result of JP2’s clarification–it is between the two. Such a category did not seem to formally exist in a prior document. Nonetheless, we know that JP2 intended to make this category normative since, when he issued his apostolic letter he also added a paragraph to Canon 750 of the
Code of Canon Law which mentions these issues. Here is an English translation:
“Each and every thing which is proposed definitively by the magisterium of the Church concerning the doctrine of faith and morals, that is, each and every thing which is required to safeguard reverently and to expound faithfully the deposit of faith, is also to be firmly embraced and retained; therefore, one who refuses those propositions which are to be held definitively is opposed to the doctrine of the Catholic Church.”
