ANSWER:  The pope!  (Pope Damasus I)


St. Jerome translated the bible into Latin from Hebrew and Greek. St. Jerome’s early 5th century translation is known as the Vulgate, because it was written in “Vulgar Latin,” or everyday Latin. He is known as “Father of Biblical Science.” Another accomplishment of St. Jerome was founding a monastery.


St. Jerome is “traditionally regarded as the most learned of the Latin Fathers,” according to Encyclopedia Brittannica.


“At Antioch, in 375, he experienced a vision in which Christ reproved him for his pagan studies. Renouncing his classical scholarship, he fled to the desert to live as an ascetic and to devote himself to scriptural studies, for which he learned Hebrew,” according to Columbia Encyclopedia (6th edition).
