You're attempting to make up a principle that doesn't exist.
For 1600 years the "Majority Opinion" was taught and believed by everywhere and by all; if that doesn't make it part of the Ordinary Universal Magisterium, then I don't know what does.
But here's your epic fail.
EITHER the Majority Opinion is true OR the Minority Opinion is true. If the minority opinion is true (i.e. not an error), then the Church tolerated the erroneous majority opinion for, say, 1950 years (as it was still widely held in the 1950s). So then the Church failed on your made-up "passive infallibility" there.
THIS DOES NOT EXIST. There are simply things that the Church CHOOSES not to pass judgment on for one reason or another. There have been MANY such disputes on which the Church has decided not to pass judgment, perhaps the most famous of which involves the Dominicans vs. Jesuits on grace and free will. In fact, the Dominicans / Thomists rightly accused the Dominicans / Jesuits of (at least a very mild form of) Pelagianism. And it was application of this incipient Jesuit Pelagianism that eventually led to the full-blown Pelagianism and rejection of EENS that we see today. Your yourself are a (willing) victim of this. Jesuits accused the Thomists of being Calvinists. But the Church decided NOT to intervene at that time. IMO this was a huge mistake. But God allowed it because it would set in motion a series of developments that would lead to this modern-day testing of the faith and sifting of the faithful. Be very afraid, Nado, lest you be among those sifted out.
