As a Doctor of the Church he was commissioned by Pope DAMASUS-I to revise and correct the Gospels. The New Testament was already in Latin but the Old Testament was still in Hebrew.

In his early days he had done a stint in the desert and knew a thing or two about ‘temptation tripping’. Perhaps he missed it.
