In the extract from the CDF below, the “first paragraph” refers to the following:
*“With firm faith, I also believe everything contained in the word of God, whether written or handed down in Tradition, which the Church either by a solemn judgment or by the ordinary and universal Magisterium sets forth to be believed as divinely revealed.”*and “second paragraph” to:
“I also firmly accept and hold each and everything definitively proposed by the Church regarding teaching on faith and morals"
In connection with these, Cardinal Ratzinger, for the CDF, writes:*The Magisterium of the Church, however, teaches a doctrine to be believed as divinely revealed (first paragraph) or to be held definitively (second paragraph) with an act which is either defining or non-defining.
In the case of a defining act, a truth is solemnly defined by an ‘ex cathedra’ pronouncement by the Roman Pontiff or by the action of an ecumenical council.
In the case of a non-defining act, a doctrine is taught infallibly by the ordinary and universal Magisterium of the Bishops dispersed throughout the world who are in communion with the Successor of Peter. Such a doctrine can be confirmed or reaffirmed by the Roman Pontiff, even without recourse to a solemn definition, by declaring explicitly that it belongs to the teaching of the ordinary and universal Magisterium as a truth that is divinely revealed (first paragraph) or as a truth of Catholic doctrine (second paragraph).
Consequently, when there has not been a judgement on a doctrine in the solemn form of a definition, but this doctrine, belonging to the inheritance of the depositum fidei, is taught by the ordinary and universal Magisterium, which necessarily includes the Pope, such a doctrine is to be understood as having been set forth infallibly.(17) The declaration of confirmation or reaffirmation by the Roman Pontiff in this case is not a new dogmatic definition, but a formal attestation of a truth already possessed and infallibly transmitted by the Church.*And Note 17 reads:
*It should be noted that the infallible teaching of the ordinary and universal Magisterium is not only set forth with an explicit declaration of a doctrine to be believed or held definitively, but is also expressed by a doctrine implicitly contained in a practice of the Church’s faith, derived from revelation or, in any case, necessary for eternal salvation, and attested to by the uninterrupted Tradition: such an infallible teaching is thus objectively set forth by the whole episcopal body, understood in a diachronic and not necessarily merely synchronic sense. Furthermore, the intention of the ordinary and universal Magisterium to set forth a doctrine as definitive is not generally linked to technical formulations of particular solemnity; it is enough that this be clear from the tenor of the words used and from their context.*It should be noted that the Catechism exists to promulgate Catholic Doctrine.
