In Progymnasmata 45.9-21, Nicolaus the Sophist uses the Christian word παιδοφθόρος; ('boy-corrupter') in its typically Christian pairing with µοιχός; ('adulterer') to express what seems to be a Christian sentiment about avoiding detailed discussion of wicked acts. This suggests that he was a Christian, a possibility that previous scholars have considered but were unable to find evidence for.
