If you paid attention and actually learned something instead of believing BS propaganda you would know that the Vulgate is BS. And how should you know that if you could actually think for yourself? Because it uses the letter "J" in its stories. Why is that important? It's important because the letter "J" wasn't used as a letter in words until the Middle Ages. It was always used with certain Roman numbers. So it couldn't have been used as a letter in words in the 4th Century. http://en.wikipedia.org/wiki/J
