Well at least you made yourself clear that the early Church fathers who assembled the books we call the Bible based on the oral tradition and early Church practices were not acting under the authority of the Hoy Spirit.
Which then prompts the obvious question: What makes the books they selected and those they threw out (like the Gnostic gospels) authoritative?
God promised He would preserve His word for all generations. I trust He did that. He could have used an ass as we see with Balaam’s donkey. He could have used evil men like He did throughout history. Again, no guarantee they were correct on everything they did nor should they be relied on for everything.
