And as a reminder ....
This thread is in Traditional Theology.
Luther's (and others of the time of the Reformers) are included within this, but SO ARE the original 15 centuries of the witness of the Church that preceded them. The early councils of the Church considered the Septuagint as Scripture. (And this was THE Church before there was a separation into "Roman Catholic" etc.)
IIRC, the OT of the KJV is based on the Masoretic Text, is it not? While it bears much similarity to older texts, there are also significant differences? And it was not codified until quite a few centuries after Christ?
While I love my Lutheran brothers and sisters, and mean no disrespect, the very fact that he wished to removed James, especially, as well as Hebrews, Jude, and Revelation is of great concern to me. He also tried to get Esther placed with the "Apocrypha", I believe? And the KJV was originally put together for the Church of England. I would rather not get into the political and personal reasons the King of England wished to establish his own Church apart from the Catholics, but that would have been the impetus for the KJV, I believe. Again, no disrespect intended for my Anglican brothers and sisters. (None of us share either blame or credit for anything done by Church leaders in past centuries, and I do respect you all very much.)
(And for what it's worth, I have done almost all of my Scripture memorization in King James, and our Church often uses the NKJV - I use various translations for various purposes - I am not an "only"est of any kind.)
By the way, the Orthodox Church does not consider all of Scripture to be on equal footing either. There are several levels of authority and importance. The Gospels are primary of course - when everything is viewed through the lens of the Gospel, through the revelation of Jesus Christ the God-man as revealed to us, everything falls into place. Trying to understand the faith through the lens of the Psalms or some of the history, for example, can have terrible results (depending upon which passage is chosen - making people believe that God is very bloodthirsty and would smash infants on a rock). The epistles hold a very important place as well, and so on, through various levels of understanding. (The Psalms are also important and a number of them are read in Church every time we gather.) Context and knowing the purposes of the Scriptures are very important.
