the Father sends the spirit of truth so we can determine what is scripture and what is not. roman councils do not make these decisions.
So the Holy Bible is not confirmed by the Spirit of Truth? You can't have it both way.
Many think the Catholics determined what books were to be included in the Bible, because they, over the centuries, publicly listed the books that they used.
There were canons put together and used by people even before the Catholics. Different people gave personal statements about the books and letters, but
they were only commenting on the books and letters that the first Christians used from the beginning. They had only acknowledged those books early Christian communities already accepted as scripture.
The Catholic denominations started to introduce heresies in approximately 310 A.D. The Bible was put together before that. The Roman Catholic Church, which taught things contrary to the Bible, began with the prayers for the dead and the sign of the Cross. The Catholics continued to bring in many false teachings.
Official canonization of the New Testament scriptures came about because of heresies Gnostics and other sects spread. The first Christians accepted as scripture New Testament teachings by letter and books right from the beginning.
The New Testament teachings were by letter and books right from the beginning. We can see in 2 Peter 3:15-16 Peter recognizes what Paul writes as scripture. Paul speaks Old Testament to the Gentiles many, many times, possibly hundreds of times.
2 Peter 3:15 Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.
Again, the believers from the beginning used these books and letters from the start.
That is what determined these books as scripture.
