A curious thing strikes me about the Bible, we that believe it is the word of God do so and never once question the fact that it is a translation by a gang of monks we don't even know or know were honest and trustworthy. How do we know they did it correctly? How do we know they didn't add to or take away from it?
We can trace every book of the NT to the 1st century AD. 1 Corinthians was written in 55 AD at the latest. There is a referey to the Pool of Bethesda in the Gospel of John which for many years was thought to never exist. It was discovered in the exact location as described in the Gospel, during an excavation of Jerusalem in the 20th century.
