C’est exact

Le magistère ordinaire (comme une encyclique, un discours à des corps constitués etc) est également infaillible.

Donc on ne peut pas dire comme certains voulant à tout pris dire que Jean xxiii et ses successeurs sont papes malgré les hérésies énormes proférées au faux motif que l’infaillibilité papale n’a été engagée que pour les dogmes de l’immaculé conception au XIX e siècle ou de l’assomption en 1950

Donc la majeure du syllogisme de Avemaria44 est bonne « le pape est infaillible dans son magistère - sous entendu extra ordinaire comme ordinaire - en ce qui concerne la foi et les mœurs (et les autres conditions annexes) »
(RappelMineure lez papes depuis Jean xxiii débitent des hérésies sans arrêt y compris Vatican II valide par Paul vi - conclusion ils ne sont pas papes hélas)

J’en apporte la preuve à travers les enseignements de Vatican I, une encyclique de pie IX précisant la notion de magistère ordinaire et l’encyclique humaniste generis de pie xii

Voici lez explications : (en anglais mais vous avez Google translate)
Vatican I constitution dei filius range explicitement le magistère ordinaire dans la catégorie infaillible
«

All those things are to be believed with divine and Catholic faith which are contained in the Word of God, written or handed down, and are proposed by the Church either by a solemn judgment or by her ordinary and universal magisterium to be believed as divinely revealed.
(Dogmatic constitution Dei Filius, chapter 3, “Concerning Faith”, Denzinger 1792) »

Précisions sur la notion de magistère ordinaire qui est infaillible dans une encyclique de pie IX de 1863:

It should also be noted that when the Fathers of the 1870 Vatican Council were discussing the draft of Dei Filius before voting, questions were raised about the meaning of the word “universal” in the expression “Ordinary and Universal Magisterium” and the Council’s official “relator”, Bishop Martin, referred them to Pope Pius IX’s Tuas Libenter (21stDecember 1863). This document (Denzinger 1679-84) clarifies exceedingly well the obligations of the faithful regarding acts by which representatives of the teaching Church communicate doctrine to them. Here is the most relevant part, which confirms precisely the words of Mgr. Martin:

Even limiting oneself to the submission made by the act of divine faith, this could not be restricted to those things that have been defined by the express decrees of ecumenical councils and by the decrees of this See, but must be extended also to what is passed on as divinely revealed by the Ordinary Magisterium of the whole Church spread over the world…
(Denzinger 1683)

Thus the “Ordinary and Universal Magisterium” designates the teaching power of the pope and bishops of the whole world together. No special kind of teaching is required. Nor is it necessary for the teaching to be given over a lengthy period of time.

human generis de 1950 de pie XII dit clairement que lez enseignements du pape dans les encycliques est aussi infaillible dans la lignée de Vatican I

In 1950, Pope Pius XII published the landmark encyclical Humani Generis, an absolutely critical document that refuted many theological errors renascent at the time, including the idea that the ordinary teaching of the Pope is little more than an opinion one can choose to take or leave. The Pope shot this down when he stated clearly: “Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent, since in writing such Letters the Popes do not exercise the supreme power of their Teaching Authority. For these matters are taught with the ordinary teaching authority…” (Humani Generis, n. 20).
