Although these two are used by Christians all over the world, however, there are certain differences between the two. The Catholic Bible is usually considered to be the general name for the Bible used by Christians. Most of the words in the Catholic Bible were written using Latin Vulgate. On the other hand, the King James Bible is one of many other existing versions of the Holy Bible.
This is basically one of the major differences between the two. The King James Bible refers to one of the versions of the Holy Bible, and it was written in the 17th century by the English King James. Although there are other versions of the Holy Bible that were made from the Catholic Bible, it is believed that the King James Bible was the first to be written from the Catholic Bible.
Another difference is that the Catholic Bible contains more Hebrew and Greek words in their actual meanings. In contrast, some of these Hebrew and Greek words were poorly translated by those who wrote the King James Bible.
