Born in Dalmatia of a Christian, Jerome (345-420) was baptized in Rome, while taking his classical courses. He then studied under the best masters in foreign cities. But the Church had need of this extraordinarily gifted man. Jerome heard and obeyed the divine call, made a vow of celibacy, and withdrew for four years to a hermitage in the Syrian desert. The Holy Father soon summoned Jerome to Rome and entrusted him with the enormous task of revising the Latin Bible. This work, which took 30 years to complete, is the Vulgate version of the Scriptures. He also wrote many other works, mostly commentaries on the books of the Bible.
