I think the history of the NT as a book (or books) is fascinating and surprising, and it's appalling how little the average Christian knows about it.
There's a tendency in some circles to lie about it, so they're not able to celebrate the truth, which is pretty amazing and worth celebrating.
I came at it as a Jew turned atheist. Most of what I've learned about it has been since becoming an atheist.
So I had some vague preconceived notions.
When I learned that the first bits we have now are thought to have been written down within a few decades of Jesus' death, I was flabbergasted. I had to change my entire world-view. That's amazing! Christians should be broadcasting and celebrating this! It should be commemorated and marked as a holiday.
But since some pastors are going around telling their congregations that the gospels were written by eye-witnesses right after Jesus' death, they can't celebrate this truth.
Similarly, the history of the reconstruction of the early Greek manuscripts is riveting. But since some pastors are going around saying that the "original manuscript" contains "no errors," (there is no original manuscript.),` they can't really talk about this fascinating history, which IMO supports their religion, if anything. They've taken away from themselves the powerful weapon of the truth, in favor of inaccurate stories from centuries ago.
The earliest scrap of NT manuscript we have is called P52, and was discovered about 50 years ago. It's a small papyrus fragment of the Gospel of John (18:31-33 on the front; 18:37-38 on the back), and it has been dated to about 125 AD. Isn't that amazing? Isn't that earth-shattering? It's somewhere in the Princeton University Library. Is there a huge shrine? Can Christians come and venerate it and stare at it in wonder? No. If this were a Jewish scrap, it would be the holiest object for the world's Jews. Very few Christians even know it exists.
Christians! You're short-changing yourselves! As usual, reality is much more exciting and amazing than the lies your preachers are feeding you!
