St. Jerome was a master of the Latin and Greek. His native tongue was Illyrian which I would assume is a Greek dialect. Old Latin - meaning? The saint was versed in real Greek. The Hebrew scriptures went first to the Greek and then to the Latin via Jerome. This man suffered and he knew the languages. Of course Marty used Jeromes Vulgate - that was all there was!!! and I repeat - Marty was a failed Augustinian. Do you suggest that 1 1500s Martin Luther was more in tune than a 300s scholar who was much closer to the texts and a language expert?? No logic to that premise.Nope...There were copies made into the Syriac language as well as the Old Latin...If I remember correctly, the Orthodox church still has some of these old Latin Bibles laying around...
Jerome translated the Old Latin into his new Latin, the Latin Vulgate...
