Which version of the Bible is the correct version?
The Greek one.
We adhere to the preservation of the Scriptures to English-speaking peoples in the King James Bible. Send me a personal email, and I'll give you (free of charge) some very good materials on manuscript evidence, and the problems with the English Bibles of the 20th Century.
You know the old joke: King James, if it was good enough for Jesus, it's good enough for me. Mark my words, somone will show slavish devotion for the KJV and outright contempt for any other translation in answer to your question.
That's a pretty broad question. Do you mean which English translation is the correct one? Frankly none of them are. They all have their good points and bad points. For example, the NASB is grammatically correct but somewhat wooden while the NIV is easier to read but in some cases is a little more loosely translated. Even though none is perfect they give us enough to be able to study and know God's word without all of us having to learn Greek, Hebrew and Aramaic.
There are a numerous families of texts for both the Hebrew and the Greek but amazingly enough none of the difference affect areas where doctrine is in dispute. Most of the differences involve word order (Christ Jesus vs Jes Christ) or inclusion of or exclusion of verses (The end of the Gospel of Mark is in some ancient texts but not in others). But again it is not anything that affects essential doctrines of the Christian faith.
Catholic's and Protestants disagree regarding the inclusion of the Apocrypha. I believe Jerome did not want to include it when her translated the Bible into Latin and I am pretty certain that most Jews do not recognize the apocryphal books as co-equal with scripture. But outside of that Catholic's and protestants have the same scriptures.
So what was the point of your question?
