It's not an ontological impossibility for one magisterium to contradict another because it is happening with a great deal of regularity lately. When all prior popes urged Catholics to stay away from other religions and this Pope kisses the Koran, you know something is amiss. When he opposes capital punishment, he is equally out of sync with past magisteria. When this magisterium reverses Catholic teaching on Jewish expectations for the Messiah, or when it embraces the Lutheran understanding of Justification, it is doing precisely what you say it can't. So something is wrong. You want Catholics not to THINK. This is why we are in crisis: Vatican II was a liberal REVOLUTION in the Church--and revolutions by their nature are not Catholic. It is not the provence of a magisterium to revolt against the past but to be preeminantly conservative of the Church's heritage. It is its job to protect and hand down the deposit of Faith, not invent countless novelties.

I would suggest you consider joining narses in his autocephalic church, but I sense you already have your own Communion. Well, maybe an alliance :)
