Know what solves all the debate? Christians technically don't need a "Bible" as it stands today. Whether protestant or RCC, not once, spoken or written, have Christians ever been told that they need a Bible or are commanded to believe in a Bible. The scriptures for Christians today should be the gospel accounts when it comes to understanding and believing the Gospel of Christ. The epistles are good for historical understanding of the early church.
Think about it. If one consolidates Christianity to the Gospels, separation from the OT means that Christians don't need to explain the OT warring God and the difficult questions and actions wrongly attributed to God. One doesn't have to explain the OT stories like Noah and Flood. We don't have theologians and modern pastors trying harmonize theology and beliefs from the OT with the Life of Christ and Epistles. The primary purpose of the OT then is to point to Jesus. That's it. If someone asks you if the Flood was a literal historical event, the answer now becomes, "Who cares, Jesus never said a belief in the flood was necessary for salvation", and you move on. Period.
One doesn't have to worry about eschatology, Calvinism vs Arminianism, baptist vs. methodist and all the other junk that has come out of the need to have an infallible "Word of God".
Instead the only doctrine is Jesus and his example. The first century Christians never had a bible. Most couldn't read or write. Their belief was only in Jesus. Why should it be any different today? Unfortunately, "The Bible" has caused more division in the "Church" than was ever intended; denominations, theology, executions, crusades, inquisitions, etc., all over a book that Christians were never told to make or have to believe in.
