Here is some information: The King James Version differs from the newer versions 5% of the time. Because it was written from the body of manuscripts called the Textus Receptus, or Recieved Text. For the new testament, there are 5,309 surviving Greek manuscripts which agree 95% of the time, exactly. The modern versions also used the Textus Receptus, but it disagreed with two very old, yet very corrupted manuscripts; the Vaticanus and the Siniaticus, they preferred the corrupted manuscripts over the Textus Receptus, accounting for the 5% corruption in the modern versions. Here are some examples:
I Timothy 3:16 And without controversy great is the mystery of godliness, GOD was MANIFEST IN THE FLESH...KJV
I Timothy 3:16 And by common confession great is the mystery of godliness: HE WHO WAS REVEALED IN THE FLESH...NASB
KJV says GOD was manifest in the flesh, meaning Jesus is GOD, very important for the doctrine of the diety of Christ.
Romans 14:10b,12: For we shall all stand before the judgement seat of CHRIST...So then every one of us shall give account fo himself to GOD. KJV
Romans14:10b,12: For we shall all stand before the judgement seat of GOD...So then each of us shall give account of himself to GOD. NASB
One word is changed, erasing the diety of Christ. Pretty tricky.
Here is one more on Christ's Diety:
Acts 20:28 ...to feed the church of GOD which he hath puchased with HIS OWN blood. KJV
Acts 20:28 ...to care for the church of God which he obtained with the blood of HIS OWN SON. RSV
God's church was bought by God's blood, therefore CHRIST is GOD, RSV separates Christ from God proving nothing.
Well, there are MANY verses that attack the doctrine of the diety of Christ, the virgin birth, atonement by faith, the physical resurrection of Christ, and His Second Coming. I have a bunch, but, not the time. A good book is "Lets Weigh the Evidence" by Barry Burton, get at local Christian Bookstore. Peace!!
