Well, if you don't mind me jumping in here. I don't know that the English translation of the bible is what they are necessarily talking about. But who knows, they could be.
In any event, at least from the oldest manuscripts, the texts are very close to one another, which is one archeological way to authenticate an ancient piece of writing. That said, anything interpreted in another language other than the ones originally written (Hebraic, Aramaic, Ethiopic, Septuagent, Greek, etc.) leaves room for interpretive error or misjudgment simply because of the vast differences in language construction and use. Not to mention, personal or kingdom (earthly that is) predjudices, and oppression techniques. (Side note: What better way to keep a people in "check" than to write it into a "sacred" book that is translated from one language into yours, and put in your own personal desires and then call it God's word. That being the case, would be easy to hoodwink an entire nation/culture into believe that if they disobey that sacred writing, they would be disobeying GOD, and thereby would be punished severely, or even put to death....Easy way to maintain order and allegience in your kingdom, don't you think??? That's one of the flaws of the KJV of the english bible, because that is in large part what constantine did when he had the first english bible put together...but I digress!)
Now that being said, if you want to listen to someone who has knowledge of the languages of almost all of the ancient manuscripts found so far, and who also has the historical, archeological, and social contextual knowledge of the places and times of the different stories in the bible, I would recommend highly the following person. Her and her late husband have acquired as part of their university collection (both were/are university professors) some of the oldest manuscripts found to date. She has I think the Latin Vulgate and Greek Septuagent in her collection.. She shows them from time to time. Anyway, I would like to tell you, she is a female pastor for a church in California (Los Angeles I think), she is wonderful in her teaching style if you really want to get down to the nuts and bolts of the original languages of the bible. Not only that but you will hear her say OVER AND OVER again, that we should not be in each other's "backyards" telling them what their property looks like, or where it needs repairs. In other words, dealing with "sin" (as identified and defined from a typical judeo-christian standpoint - not necessarily of the fundamentalist or religious right perspective) Anyway. In other words, from her standpoint, dealing with sin is the Holy Spirit's job, and not peoples. So as people, she will say over and over again, worry about yourself and don't worry about other people's sin, deal with your own and I'll deal with mine.
She used to be on tv, but I think it's gotten too expensive for her to remain there. But she broadcasts her messages 24 hours a day on her website which is

This is what biblical teaching should be, not that fundamentalist, hell, fire, brimstone, and prosperity crap that's out there now.
Enjoy, I hope this sheds some light!!
