Well, it is not true that all of the translators were Calvinists.
There were also Arminians on the KJV translation committee, too. In addition, when they translated, much of the New Testament was taken from William Tyndale and he did not accept Calvinism at all. You might see certain sources say that Tyndale was Reformed in his teachings, but this was not in reference to Calvin’s teachings if you look deeper. In fact, I just double confirmed it with Perplexity.ai. Now, yes, I know that the word “Reformed” today is a code word for “Calvinism.” I get that. But when we refer to the Reformers in the Protestant Reformation, not all of them were Calvinists. I have had my many debates with Calvinists over the years. Some have been cold and nasty towards me, and others have not been (like Will Kinney, and Rich Christiano, director of the Christian movie, Time Changer). However, while I am commanded to love everyone (even my enemies), I am no friend of Calvinism by any means. It is an unbiblical concept that needs to be preached against, and its origins are tied to a man who was not good.
King James believed that the Puritans and the Geneva Bible were hostile to the monarchy, while he saw the Church of England as reinforcing the king's authority. The fact that the Geneva Bible was not updated is one clue that King James did not agree with their theology. The Geneva Bible had all their Calvinist theology in it (with its added notes).
King James held strong convictions on the Divine right of kings, and even wrote a book on the subject. To that end, he continued to suppress many of the important aspects of the Puritan movement (which is primarily Calvinism), including the many Puritan's Congregationalist and Presbyterian views of Church government. So James was no real supporter of Puritanism and Calvinism.
(Side Note: Keep in mind that while most Puritans held to Calvinistic theology or TULIP, not all Puritans held to Calvinism or TULIP).
Anyway, the KJV translation was also opened to the public at times with difficult verses. In fact, there are many statements in the KJV that easily refute Calvinism like 2 Thessalonians 2:10, Matthew 23:37, and Jonah 3, etcetera. There are many others verses I can reference in the KJV that destroys Calvinism back where it came from. If you were to compare the KJV with the Tyndale translation at TextusReceptusBibles.com, you would see that there was no nefarious changes to the wording by the translators who were Calvinist. No doubt, the Arminians on the translation team would have called them out on it if they did.
Here is a snippet from my write-up involving the KJV and America that ties into this discussion.
View attachment 261220
So by the 18th century (1700s), the KJV was the primary and dominant translation here in America. It was THE Bible to the American people. The first Bible printed here in America was the Aitken’s Bible. It was even endorsed by Congress. While it was not a financial success, others took up the helm in successfully providing the KJV to the American people. The KJV was the Bible taught in public schools until the early 1960s (Which was coincidentally the time when the Modern Bibles started to become popular). The KJV was used by abolitionists to end slavery here in America. At one point, Frederick Douglas worked with Abraham Lincoln. Abraham Lincoln received a felt covered KJV from the black community for his efforts in fighting slavery. The KJV is the most printed book in the world, and has caused great revivals through history. Where are the great revivals with the Modern Versions that change doctrine for the worse? Modern Bibles attack the eternal nature of Jesus Christ. They do not teach you not to have fellowship with a Joel Olsteen (See 1 Timothy 6 in the KJV and compare it with the Modern Bibles).
In any event, I hope this helps, and may God bless you, Stan.
