You keep missing the point that the books in the Bible did not fall from the skies and self assemble themselves in the order you find them. For some 300 years they were put together by the early Church fathers. This authority was not plucked out of thin air to authenticate the very Word of God.It was under Petrine authority. Go read their writings like St. Irenaeus and others.
This is precisely one of the main reasons why preeminent Protestant theologians converted to Catholicism. Read all of Dr Anders’ soul searching story, if you haven’t done so. The Bible itself tells us that there were many things Christ said that if written down would not fill the whole world. This oral tradition was carried out by and under the authority of ONE Church. This authority did not collapse with the Reformation.
I heard Tim Staples tell about his journey yesterday. It was very similar to what Anders went through. They were both deeply anguished that they were unable to prove that Catholic teaching was in error. Tim talked about how he would over and again say to himself “I am NOT Catholic” until he could no longer deny it.
