"It is an indisputably established historical fact..."<quoted text>
Don't be foolish, educate yourself.
It is an indisputably established historical fact that St. Peter laboured in Rome during the last portion of his life, and there ended his earthly course by martyrdom.
The essential fact is that Peter died at Rome:
this constitutes the 'historical' foundation of the claim of the Bishops of Rome to the Apostolic Primacy of Peter........
"You should understand that history is not a subjective ideal from your mind.
History is actual documented fact...."
So where's the documentation links to back up these claims?
