 Julian's religious agenda gave him even more work than the average emperor as he sought to instruct his newly-styled pagan priests and he had to deal with discontent Christian leaders and communities.An example of him instructing his pagan priests is visible in a fragment in the Vossianus MS., inserted in the Letter to Themistius.Additionally, Julian's hostility towards the Christian faith inspired vicious counteractions by Christian authors as can be seen in Gregory of Nazianzus' invectives against Julian.
