Perhaps you should read “The True Story of the Vatican Council”. That would be Vatican I. It was written by Henry Cardinal Manning, a convert from Anglicanism, who participated in that Council. Cardinal Manning sheds some very important light on the topic. Stanley Jaki wrote a great introduction to this edition of the book by the way.
"Another supposed consequence of the Vatican Council was the “Old Catholic Schism.” And here in justice it must be said that the opposition of governments and political parties was not spontaneous or without instigation. We have seen with what perseverance the fears of statesmen and cabinets were worked upon, and we know how ubiquitous and how subtle has been the activity of the international Revolution. But another cause was open and palpable. The “Old Catholic” schism in Germany appealed to civil power, and the civil power promptly recognized and copiously paid its ministers. It seemed to bring the promise of a German National Church, representing the mind of the nation and without dependence, as Dr. Friedbergh has it, on “the man outside of Germany.” But the “Old Catholic” schism was not the consequence of the Vatican Council any more than was Arianism the consequence of the Council of Nicea. The definitions of the Council were indeed the occasion of the separation of a small number of professors and others from the unity of the Church, whose antecedents had for years visibly prepared for this final separation.
The strange medley which met at Augsburg and Bonn and Cologne, of Rationalists

and Protestants, and Orientals and Jansenists and Anglicans, was not the consequence of the Vatican Council. Every sect there represented had been for generations or for centuries in separation and in antagonism to the Catholic Church."
History shows, GK, that once the government could not enlist all of the Catholics into the state sponsored Old Catholic Church the government pulled the plug on their financial support and the-man made construct, truly Protestant in nature, called “Old Catholics” was relegated to the scrap heap of history proving that they, the Old Catholics, were not of divine origin.
And really GK, “Rationalists and Protestants, and Orientals and Jansenists and Anglicans”? Can you imagine sitting in room listening to their deliberations, trying to hammer out some type of agreement without betraying their own confessional statements non-binding though they are?
Now that is what I would call “motleydom

” to say the least! And I am sure “common sense” would agree.
