Reddit reviews The Unauthorized Version: Truth and Fiction in the Bible

It's too complex an answer to get into in just a few quick sentences. You really need to go find books on the subject.

For example, the movie The Sixth Sense is fiction. But there really is a place named Philadelphia and there's such a thing as child psychologists.

Many of the books tell fantastic stories but refer to real cities and names of real people. Some refer to made-up cities and made-up people. There have been entire books vetting single sentences. And they often disagree.

Here is one book I recommend, it's very easy to digest for light readers.

Non necessariamente. Quello lo fanno i filologi e gli storici. Io poi, da lettore qualunque, leggo i loro libri. Ad esempio questo qui che ho da diversi anni ma che ancora non ho letto perché prima vorrei leggere la bibbia o almeno le parti più importanti.

Two works of genius I would recommend:

The Unauthorized Version: Truth and Fiction in the Bible by Robin Lane Fox

God: A Biography by Jack Miles

Also anything by Bart D. Ehrman

Nevertheless, from an atheistic perspective and within the english translations there are contradictions that people can and will point out. A blanket statement denying all contradictions is provocative and will simply undermine your further arguments to any that are not approaching the Bible from a Christian perspective. You've got to meet people halfway.

As a side note, since you seem interested in the subject, you might like to read this. It's a book on the Bible from the view of an atheist historian, but he is unfailingly respectful in his writing, and has taught me an awful lot. While you probably won't agree with all of it, you may enjoy it. The final paragraph of the preface should give you something of an idea:
> When I had almost finished, a friend reminded me that I had once remarked to him that I believed in the Bible, but not in God. I had long forgotten this remark, but it must have remained latent in me. Twenty-five years later, this book has turned out to be an explanation of what I meant.
