For those who wish to read just one of MANY such reviews of the New International Version and why it does not have much favor with most Christians, I am providing a link to an in-depth review from a Baptist denominational writer. You can GOOGLE "Review: NIV Bible" for many more such criticisms.

Those publishers who change the original Word of God through deliberate bias and 'political correctness' are no friends to Christian Bible Students. This NIV 'version' is just one of many that do not even resemble the Original words from the Hebrew, Aramaic, Chaldean and 'street' Greek manuscript texts and are deliberately misleading. I can not substantiate this (yet), but my personal opinion is that the NIV was produced by non-Christians or even Kenites.
