St. Jerome

The enormous scholarship of St. Jerome, born about 340 and dying September 30, 420, made him not only the foremost authority within the Church itself throughout the Middle Ages, but also one of the chief guides to secular scholarship. Abélard repeatedly quotes from him, particularly from his denunciation of the revival of Gnostic heresies by Jovinianus and from some of his voluminous epistles. He also refers extensively to the charges brought against Jerome by reason of his teaching of women at Rome in the house of Marcella. One of his pupils, Paula, a wealthy widow, followed him on his journey through Palestine, and built three nunneries at Bethlehem, of which she remained the head up to the time of her death in 404.
