What the Bible Societies say about the 1909 compared to KJV.
As a King James Bible Believer, I want the Bible that is closest to the King James Bible. And, most "Independent Baptist Missionaries," as myself, take a strong stand for the King James Bible in English as well. But, when it comes to the Spanish language, many of them choose to use the 1960 Spanish version. But, is it closer to the King James Bible? Let's look at what the modern day Bible Societies who print both the 1909 and 1960 have to say about the 1909.
The Bible League:
"A hardcover Spanish whole Bible using the text of the 1909 Reina-Valera version, comparable to the KJV text."
United Bible Societies:
"This  is the first revision in the 20th century of the original translation of Cassiodoro de Reina and Cipriano de Valera. This work was coordinated by the British Foreign Bible Society. This version conserves its classical beauty and has served the evangelical church for decades."
How come they don't say this about the 1960? Well, if you'll study the issue, you'll see for yourself (as I did) that the 1909 Reina-Valera is much closer to the King James and original 1602 than the 1960. In fact, the 1960 is much closer to the English Revised Standard version!
Sadly, the 1909 also has problems and reads with the Critical Texts time and again, so does the 1865. That's why the Valera 1602 Purified is so great, for it doesn't!
