Section V, item #1. Read what Fr. Cekada said the pope said, then read what the pope actually taught, and you will see the blatant misquote which in my opinion, was intentional.

With that misquote, Fr. Cekada is accusing the pope of preaching a NO doctrine.

II. You must believe those teachings of the universal ordinary magisterium held by theologians to belong to the faith (Pius IX).
• “For even if it were a matter concerning that subjection which is to be manifested by an act of divine faith, nevertheless, it would not have to be limited to those matters which have been defined by express decrees of the ecuмenical Councils, or of the Roman Pontiffs and of this See, but would have to be extended also to those matters which are handed down as divinely revealed by the ordinary teaching power of the whole Church spread throughout the world, and therefore, by universal and common consent are held by Catholic theologians to belong to faith.” Tuas Libenter (1863), DZ 1683.

III. You must also subject yourself to the Holy See’s doctrinal decisions and to other forms of doctrine commonly held as theological truths and conclusions. (Pius IX).  
• “But, since it is a matter of that subjection by which in conscience all those Catholics are bound who work in the speculative sciences, in order that they may bring new advantage to the Church by their writings, on that account, then, the men of that same convention should realize that it is not sufficient for learned Catholics to accept and revere the aforesaid dogmas of the Church, but that it is also necessary to subject themselves to the decisions pertaining to doctrine which are issued by the Pontifical Congregations, and also to those forms of doctrine which are held by the common and constant consent of Catholics as theological truths and conclusions, so certain that opinions opposed to these same forms of doctrine, although they cannot be called heretical, nevertheless deserve some theological censure.” Tuas Libenter (1863), DZ 1684.
