From an older thread:
Dogma and Doctrines
The two categories of Magisterium are “extraordinary”, and “ordinary universal”.
The question of doctrine and dogma:
From Vatican I (Pastor Aeternus), for infallibility to be exercised the Pope must teach
(a) ex cathedra (from the Chair of Peter), that is as Shepherd and Teacher of all Christians,
(b) speaking with Peter’s apostolic authority to the whole Church,
(c) defining a doctrine of faith and morals.
So the Pope’s ‘ex cathedra’ definitions may be either of revealed dogma, to be believed with divine faith, or of other truths necessary for guarding and expounding revealed truth. Vatican Council II and the post-conciliar Magisterium have explicitly affirmed that both ecclesial and papal infallibility extend to the secondary doctrinal truths necessary for guarding and expounding revelation. Thus Humanae Vitae (Encyclical) against contraception, and Ordinatio Sacerdotalis (Apostolic Epistle) on male-only priests, contain infallible doctrinal definitions, to remove all doubt.
Vatican II (Lumen Gentium, 25) reaffirms this teaching: “The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful – who confirms his brethren in the faith (cf. Lk 22:32) – he proclaims in an absolute decision a doctrine pertaining to faith or morals.” Vatican II, reiterated the teaching of Vatican I on papal infallibility, and its documents are readily available [from the EWTN Library (
http://www.ewtn.com/vlibrary/search.asp, or the Vatican Library) for anyone with the will to know what Christ’s Church is teaching, like most of the documents of Vatican I, and the papal documents before and since Vatican II
Thus, no dogma has to be affirmed, nor anyone anathematized, nor the word “define” or “definition” be used for an infallible papal teaching – only that the Pope is handing down a certain, decisive judgment that a point of doctrine on faith or morals is true and its contrary false.
Ad Tuendam Fidem
A category 1 truthThe CCC #88 (1997) clearly combines exactly with Pope John Paul’s Motu Proprio (= on his own authority) Apostolic Letter Ad Tuendam Fidem, 1998 (ATF), which requires the assent of divine and Catholic faith to believe (credenda sunt) dogmas (a category one truth) (Canon #750.1).
Such would be the dogma of the Immaculate Conception and the Vatican I dogma on papal infallibility.
A category 2 truth requires the assent of ecclesial faith, as a secondary truth, “proposed definitively” (definitive proponuntur) to be “firmly embraced and held” (now Canon 750.2). In fact, the 1983 revision of Canon Law had replaced in #749.3 “dogmatically declared or defined” with “infallibly defined”, thus NOT expressing a limitation of infallibility to dogmas. ATF better enables Canon Law to apply to the understanding of infallibility with the Profession of Faith covering the two categories of infallible doctrine.
Such as in the Encyclicals Casti Connubii (1930) and Humanae Vitae (1965) against contraception, and in Ordinatio Sacerdotalis on male-only priests.
The category 3 truths are non-definitive (non-infallible) and require intellectual assent (“loyal submission of the will and intellect”, Vatican II, Lumen Gentium 25), not an assent of faith.
In Summary.
The three levels of teaching are:
- Dogma – infallible (Canon #750.1) to be believed with the assent of divine and Catholic faith.
- Doctrine – infallible (Canon #750.2) requires the assent of ecclesial faith, to be “firmly embraced and held”.
- Doctrine – non-definitive (non-infallible) and require intellectual assent (“loyal submission of the will and intellect”, Vatican II, Lumen Gentium 25), not an assent of faith. [See Ad Tuendam Fidem, Bl JPII]
