"As anyone not a Jew is a Gentile; it seems any who claim to be a Christian who is not C is considered a P; even if they deny fundamentals of the Reformation."
It's a little bit more complicated than that. Catholics view any church that grew out or splintered off from the churches that separated from Rome in the Reformation as Protestant. So, for example, because the Quakers separated from the Puritans, who separated from the Anglicans, who separated from the Catholics, all three would be considered "Protestant" by the Catholics, even though the Quakers are not really protestant, and are really more mystics than anything else. Likewise, the Mormons, who agglomerated from adherents of other Christian sects, are Protestants in the Catholic view.
However, the Eastern Churches that separated from Rome before the Reformation: the Orthodox, the Monophysites and the Nestorians - these are not "Protestants" at all.
The Monophysites and Nestorians are simply heretical cults. The Orthodox are Catholics, in disunion with Rome.
From a Rome's eye view it's not so simple as "any Christian who isn't a Catholic is a Protestant". It would be fairer to say that any Western Christian who isn't a Catholic is a Protestant, because once the whole West was under the Patriarch of Rome.
I remember college in 1953 that I certainly was not referred to as a "seperated bretheren".
How is it that a church in Rome grew to dominate all of Christendom? What happened to all the other churches? Were there any that disagreed with the Roman seat of power? What happened to them?
The answer to these questions help demonstrate that the emergence of a church of Rome as the dominant power in the Christian world was mostly political rather than spiritual. Rome's rise in the religious world was just another way for very creative politicos to manage the fast splintering Roman empire. In fact, the RCC enjoyed even greater worldly power than its predecessor with its once-removed, puppet master rule over much of the world.
While it's very stylish and refreshing, I'm not buying your really cool mystical approach. However, I do appreciate your acknowledgment and rebuke of certain obvious abuses of the RCC. There are many here who actually defend such atrocities!
