John's authority was harshly questioned twice by Jerome, then abbot in Bethlehem. The first time was in the frame of the first polemic with Origen's followers, and is narrated mainly in Jerome's treatise dedicated to Pammachius "Contra Ioannes Hierosolymitanum (Against John of Jerusalem)", as well as in other letters of Jerome (n. 51, 82 and 86). Jerome accused John of supporting the ideas of the Origenists. In 415, two years before his death in 417, he was probably directly involved in the discovery (invention) of the Relics of Saint Stephen.
