The rest of it is contained in what Catholics call "Sacred Tradition",
I think I'll just stick the The Infallible Word Of
God if that's OK with you.
I don't think it can be properly interpreted independently of or outside of (or against) the Apostles and their successors. If it could be, then tell me: who interprets the Bible without error? If "any" independent Christian can do so, then why do these independent Christians all contradict each other?
Sacred tradition IS "The Infallible Word of God". If you really believe the Bible, you have no choice. The Bible is very clear about that.
Why is it so difficult for you folks to believe that the Holy Spirit worked to keep error out of the Bible as it was being compiled by the Catholic Church, and yet that same Holy Spirit would be unable to prevent error in the teaching of matters of faith and morals when it is transmitted by (originally) non-written means. MOST of the teaching of the Apostles was NOT written down until after their lifetimes, by those who had been THEIR disciples.
