The Vulgate

The Vulgate was not only important back in the 4th century, but even now it is important. You say how? You can read the Vulgate and it becomes a commentary in and of itself on the original languages. The word choice of Jerome in the Latin colors how he saw what the original languages said. This is an invaluable tool as a window into what Jerome and to a certain degree the church believed in the 4th century.
