So, by definition, the universal ordinary magisterium can't contradict itself because anything new is not the ordinary magisterium.
This is blatantly false and such a definition would make the OUM a useless tautology basically stating: whatever was true before is still true.
Only by redefining the magisterium can one escape the fact that the "Church" universally teaches error for the last 60 years.
I'm not the one redefining the magisterium, which, as Pope Pius XI said, is immune from error. Do you believe him?
The universal ordinary magisterium is merely what the Church has always taught in an ordinary manner, i.e. via her clergy, nuns, catechisms, etc., even parents. The extraordinary magisterium are those things taught in an unusual manner, such as ex cathedra definitions - which are also contained in the Church's universal magisterium.
Nothing is new because all that is taught by the Church can be likened to one doctrine. Not only does it all mean one thing, but it is, as it were, a single cloth woven from the top so that there are no seams, there is a perfect unity.
Therefore, any opinions, ideas or teachings that in any way teach contrary to any one of it’s doctrines, any part of this holy deposit, violates it’s holiness and the truth of God, tearing the cloth.
