And history can point to an even greater number of naughty popes.
Hey, there's even a Catholic on these threads that is currently trashing the current Pope.
It would be as if I said "The Constitution is the only guide needed for law in America" , but then continued "sadly the version we are used to is corrupted and the 2nd and 5th Amendments are hereby removed, along with some parts of Article 2."
Convenient, especially if the parts being removed or mis-translated concern things like Divorce that the secular-power responsible for the Versioning find inconvenient. (As was the case with both the English Bibles and Luther-edited Bibles.)
I think the Protestant reformation did, at least initially, draw attention to areas were the Catholic Church was very corrupt. And, as student of history I am quite willing to conceded that there were many corrupt popes.
What I'm not willing to concede is that Catholics are not Christian, that's a ridiculous and bigoted belief. To compare the Catholic Church to Mormonism is absurd. I would never say that Protestantism is like Scientology, because I am intellectually honest enough to admit that Protestants and Catholics are members of the same religion, just holding different views on things, and in my opinion neither is right about everything.
You are, sadly, continuing the great Protestant tradition of schism, breaking apart what should be one into two, three, twenty, two hundred, two thousand different entities.
If other Protestant sects disagree with your on other key doctrines (say predestination) do you also consider them Non-Christian, but an entirely different religion.
What Church did you grow up in? Have you changed from one sect to another as an adult? These are pretty simple questions which you seem unwilling to answer.
