 Since the persecution of Christians by past Roman Emperors had seemingly only strengthened Christianity, many of Julian's actions were designed to harass Christians and undermine their ability to organize resistance to the re-establishment of paganism in the empire.Julian's preference for a non-Christian and non-philosophical view of Iamblichus' theurgy seems to have convinced him that it was right to outlaw the practice of the Christian view of theurgy and demand the suppression of the Christian set of Mysteries.In his "School Edict" Julian required that all public teachers be approved by the Emperor; the state paid or supplemented much of their salaries.
