The Council’s letter shows both how unreasonable its members are and how much they are motivated by faith. Even though Nollop was not technically a religious figure prior to the letters falling, the Council now worships him above all else. The religious word choice of “heresy” implies that their analysis of the events is based not on any kind of logical, reasoned argument, but is instead based on their own superstitious interpretation. Even the word “interpretation” here implies that their argument is not necessarily based on fact, but opinion.
