We weren't even discussing that. If you mean the church was a church with a pope and celibate priests, then you're way off.
And that council was guided by the apostles and the Holy Spirit. In other words, authorized by God and directed by him to decree the letter written by the bishop of the Jerusalem church, James, not Peter.
I have already given you the reference. Here's the other proof which you will have to read for yourself. By the time Justin Martyr wrote his letters, the church fathers, including Polycarp, had quoted all but two scriptures of the entire New Testament in their own writings, including Mark 16:9-20 which some "scholars" have said was added in the second or third century.
We have the Muratorian fragment which lists virtually all of the books that were accepted and puts others out of favor. Some date it between 155 and 200. This is over 100 years prior to the council of Nicea which didn't even discuss canon. In fact, as I said, the 27 books of the New Testament were printed for that council without any discussion. It was already accepted that those 27 books were authentic. There wasn't even any controversy at that time.
Speaking of Pride. We weren't even questioning Catholicism but you've brought it up because you think this is an opportunity to assert faith in a human institution's decisions about doctrine and canon. Clearly you think men have more authority over doctrine and canon than the church without their guidance. If the councils were correct and canon could only be decided by their members, you've relegated a few centuries of Christians to be in error until the church councils could set them straight.
