I respectfully disagree with your search and information you have provided.
You need to look at what is Historical , the Eyewitnesses, and the data contextually. The issues with the RCC and what is known non-RCC stems from tradition and inspired and what is authoritative. In the RCC they say "these" all known to be the authoritative or inspired word of God because we said so. The RCC has made man the authority as to what is inspired i.e they believe tradition is also authoritative. Non-RCC says the word of God is authoritative because what is written makes it so be cause God is the author. The word is because God said. Once we understood that Jesus is God and He is the word of God His testament is Supremely Authoritative. Therefore all writing in the NEW testament MUST as they are do from Acts to REV speak of Jesus and accepted HIM as Lord in the very context of all the gospels and epistle. The other books lacked 1. eye witnesses of Jesus 2. written after 100 AD 3. were pseudo because they who wrote them were not all agreeing in the literal Resurrection of Christ WHICH IS FOUNDATIONAL FOR the Christian faith and is the Measuring ROD for what is inspired word of God. IF Jesus is not accepted, IF Jesus did not quote it as HE did we see in the NEW Testament , and the writers were not Eye witnesses to Jesus od eyeswittneses of eyewitnesses they were not accepted.
Please remember:
Polycarp, Ignatius, Barnabas, Justin , Clement , Irenaeus who was The Disciple of John. all were eyewitnesses or eyewitnesses of the Apostles who taught them. They are all from the period 67 AD - 100AD. The word of God is completely without error sir. There is no such evidence that the writing of letters to Titus, I-II Timothy were not from Paul himself. To suggest that is unfounded.
The reason why you comment here:
"So they couldn't have thought of the "Word of God" as the bible we have."
is error because Jesus Himself Set the Standard. They had the Old Testament fully and completely as we do today period. We have Historical evidence of Christ. We have the writings and testimonies of Eyewitnesses which Paul speaks about in 1cor 15. OF the Resurrection we see the words of Jesus and HIS disciples carried down through the ages by men God as used to give us what we know to be the very word of God.
