You still haven't admitted the base point of your entire argument (Peter wasn't in Rome because the Bible doesn't say so) is wrong as proved in post 251. The problem is that you misinterpret the Bible, you say Peter wasn't in Rome because the Bible doesn't explicitly say so. You would by extension say that Japan never existed / exists because the Bible doesn't say so -- it's ridiculous. Then, you say that you think the Bible underwent tampering because it came to you through The Church.
Your own personal misinterpretations would also lead you to deny the Trinity (as unitarians do) as that specific word isn't there in the Bible. your own personal misinterpretation would lead to errors like that of Arius or Mohammed (the latter probably intentional) where you would state that Christ was not God.
The Bible as given through The Church (btw The Church consists of the Latin, Maronite, Eastern Orthodox etc. Churches -- all branches of The One Holy, Catholic and Aspotolic Church) Bible as shared by Roman Catholics and other Churchs in communion with Rome is the same as the Eastern Orthodox Bible.
I gave you a list of reasons from internal evidence in the Scriptures why it is not reasonable to believe that Peter was ever a Bishop in Rome.
Men are capable of writing true histories, as you suggest. But when any external evidences contradict the internal evidences in the Book of God, it’s always best to junk what the historians have said.
And it is foolish to believe that a system as huge and defensive as the WCC (RCC) would not write or manipulate historical accounts to prop up the system. The WCC (RCC) had conquered a huge part of Europe, and the Conqueror gets to write the histories about it.
So I look at the internal evidences in the Scriptures, and if what men have written besides (including many men who are of my general heritage) rub against the the Scriptures themselves, I cut it loose like a ripped sail, and stick with the Bible.
That the Godhead is the Father, the Son, and the Holy Spirit — Three in One — One God, manifesting Himself in Three distinguishable but coequal Persons (hence man has a body, a soul, and a spirit) is provable from dozens of passages in the Bible, and the Triune Godhead would be the truth from INTERNAL evidences, even if the word Trinity had never been used to describe Him.
