You have still not posted a quote from the Bible that specifically states that all Truth about Jesus Christ and His Church are solely in the Bible.
Until you can do that, then it is your Sola Scriptura belief that is on shaky ground.
Let me get this straight...you buy the words of a broken chain of degenerates and I have to prove that Rome is NOT the center of all Christendom?
As von Dollinger notes:
"Then the Papacy sank back into utter confusion and moral impotence; the Tuscan Counts made it hereditary in their family; again and again dissolute boys, like John XII [age 16 when he became Pope] and Benedict IX [age 11 when he became Pope], occupied and disgraced the Apostolic throne, which was now bought and sold like a piece of merchandise,..."
Or Edward Gibbon writes:
"The influence of two prostitutes, Marozia and Theodora, was founded on their wealth and beauty, there political and amorous intrigues. The most strenuous of their lovers were rewarded with the Roman mitre...The bastard son, the grandson, and the great grandson of Marozia-a rare geneology-were seated in the Chair of St. Peter."
This is your gang of infallible reporters claiming your organization is the central authority? The Bible has no reference to Rome being important, but your cult requires someone prove it is NOT there? No wonder Rome cannot get any of its doctrines correct...it makes them up and argues, "Prove they are not part of tradition!" Okay, we'll just wait and see how this works out for you folks. Just remember...you were told they are false.
