If I may add something to this discussion which I hope will be helpful, during my own theological formation the Church has taken two striking approaches to scripture, both valid.
On the one hand, she has always held that the scriptures are without error, regardless of the number of rewrites and scribes, who added what or omitted whatever detail, even with missing pieces of original documents. The Church can take this position so calmly, because it has the guarantee of Jesus Christ that the Gates of Hell will not prevail against her.
If we look at the sequence of events, before there was a Bible, there was a community of believers that we call the Church. It was this community that gave us the Bible. This community decided what they wanted to put into writing in the NT. The early Church omitted pre-Christian writings that were not revelation and those that were, they bound into the OT. If we accept that the Church cannot commit an error in matters of faith, then we also accept that scriptures, as the Church gathered them and compiled them into one book called the Bible is free of error. Why? Because the scriptures are the story of this community that is error-free in matters of faith and morals. It can sin, but it cannot teach error, big difference.
On the other hand, the Catholic Church, more than any other Christian tradition, with maybe the Lutherans right alongside, subscribes to the idea that the scriptures are a legitimate area of study for academics. This means that academics at universities and other institutes of higher learning are free to study the history of the scriptures, the mechanisms that the writers used, the goals of the writers, their original message, styles, genre, language and so forth. Academics are also free to use sciences such as archaeology, physics, biology, chemistry, astronomy, history, political science, literary criticism and many other disciplines to study the scripture. The Church even encourages Catholic scholars to engage with non-Catholic scholars in dissecting the scriptures, because it makes the conclusions more legitimate if you have two converse views arriving at the same conclusion.
As to the findings of these scholars, the Church has no problem with us believing these findings as long as we remember that whatever happened way back then is God’s revelation of himself and that we arrive at a deeper understanding of what God has revealed. That’s the purpose of all this research.
The term deeper understanding means that we have only scratched the surface in our understanding of God. He has revealed himself through the Church, tradition and finally scripture, in that order, but we’re far from understanding everything that he wants us to understand about him and our relationship with him. Thus far, everything that we know about God, through the Church is 100% accurate. However, there is more. It’s like peeling an onion. Each layer of the onion is real and can be taken to the bank, but there is yet another layer waiting to be understood.
As to the different stories in the Bible, do not forget that the books fall into different genres. For example, the Pentateuch is the original Torah or Law. In it we find the story of Adam, Noah, Abraham and Moses. All of these stories were written to communicate God’s law. They were not journals nor were their authors interested in journaling. They received the Law from God and they were interested in communicating the law and the consequences for its transgression and the rewards for our fidelity. When you read them, the intellectual exercise should be to answer the question, “What is the law of God?” We will find that in understanding the law we also understand the law-giver. For example, if you look at the 10 Commandments, observe that the first three are about God. The other seven are about interpersonal relations (justice, charity, honesty, responsibility, fidelity, sacredness of life). As we examine these laws we realize that the law-giver is more preoccupied with our welfare than his. The Law reveals a loving Law-Giver.
We could go on to each section, but that would take away from this thread. There is a scripture thread which may be of some help.
God bless!
