Jerome, in his Book of Illustrious Men, or Catalogue of Ecclesiastical Writers, composed at Bethlehem about six years after Cyril’s death, writes in Chapter 112:  “Cyril, Bishop of Jerusalem, having been often driven out from the Church, afterwards in the reign of Theodosius held his Bishopric undisturbed for eight years:  by whom there are Catechetical Lectures, which he composed in his youth.”
