In 384 A.D. because of a growing need for a universal text of the whole Bible, Pope Damascus instructed his secretary to revise the Latin New Testament. The secretary's name was Jerome. So he did and his Latin translation was called the "Vulgate" from the Latin, "vulgatus" meaning common, or to make commonly known (where we get our word 'vulgar'). He also translated the Old Testament. This has been the standard version for the Roman Catholic Church ever since. They later added the Apocrypha.
