Oh noes!! Where, pray tell, did you read about this???
Just go down to the library of any theology department of any major university and you’d find shelves of library books on Petrine authority.
Oh, if you doubt Petrine authority, you must also doubt the accuracy of the books assembled as the canonical texts established in the Synod of Rome in AD 382.
And, oh, you must then think that every Tom, Dick, and Harry, and David Koresh and Jim Jones have a claim to split open the pages of the Bible and each may definitely offer their “own” interpretations.
And oh, you must then think Christ taught many truths and established many Churches each contradicting one another.
