Where in the Canon Bible does RCC get their doctrines from?

I think you'll find they are. Just as Christ is self-authenticating. "Even if I bear witness of Myself, My witness is true, for I know where I came from and where I am going" (John 8:14).

No. I can point out to you that men like Eirenaeus and Polycarp who quoted from all over the Bible and only from the Bible, years before the various councils and synods, but those men have no authority to bind my conscience any more than the councils do. The fact is that the churches accepted the canon as they received it. The acceptance of the canon by the Council of Carthage was simply a bunch of guys approving what was already common practice.

I accept the decisions of councils and synods just as far as they approved the truth, which they sometimes did. But I deny their authority. Many of them were called by Emperors rather than the churches, and some of them were renegade like the 'robber' second synod of Ephesus in 445. Likewise popes have no authority except insofar as they uphold the truth, which they cannot do because there is no such position in the Church. 'Apostolic succession' is a joke. In 1046, the Holy Roman Emperor Henry III came to Rome to be crowned. He found no fewer than three popes (Benedict IX, Sylvester III and Gregory VI) squabbling about who was the real one! So he sacked them all and appointed his own pope, Clement II. So where's your apostolic succession there?
