Like I said upstream, it was all pretty much decided much earlier. That explains why we have the books we have. The “books” we consider canon today were copied and passed around the early churches resulting in the vast number of manuscripts in existence today. They were recognized as authoritative. All Rome did was put their rubber stamp on what was already there and to this day Roman Catholics are spiking the football for acknowledging the obvious.
We have more copies of the Bible manuscripts than ANY other writings that existed in the world even a thousand years ago. That is why we can be assured that we hold in our hands and read the words God intended us to. The RCC claims of "inventing" the Bible and "giving" it to everyone is laughably arrogant. Gathering all the books that make up what is called the New Testament and putting them into a single volume is FAR from writing it and giving it to the world. You are correct that these writings were copied, collected, studied, preached, taught, read and passed on throughout the world and it was and IS God that ensured it would be. All the glory belongs to HIM.
And Catholics STILL haven’t learned from history what happens when one takes the credit and glory due God.
Maybe if they were more familiar with the Scripture they claim to have given the world, they wouldn’t be so quick to look for their spot in the sun.
