Pavel’s reference is the Magisterium from Golden Compass fictional universe The Golden Compass is a fantasy adventure film directed by Chris Weitz, from a screenplay by Weitz, and based on the 1995 novel Northern Lights by Philip Pullman, the first installment in Pullman's His Dark Materials trilogy. In the film, Lyra joins a tribe of seafarers on a trip to the far north in search of children kidnapped by the Gobblers, a group supported by the universe's rulers, the Magisterium. Fra Pavel Rasek is a monk from the world of Lyra. He knew how to use the alethiometer and worked in the Magisterium as an alethiometrist. His dæmon was a frog. The Magisterium in Geneva was essentially the headquarters and ruling authority of the Holy Church. It replaced the Papacy in Lyra's world after the pope John Calvin passed away. Any discoveries that have a bearing on the doctrines of the Church have to be announced through the Magisterium. After the existence of Dust was confirmed by an investigator of the Consistorial Court of Discipline, the Magisterium decided that Dust was the physical evidence of original sin. Every philosophical research establishment had to include on its staff a representative of the Magisterium, to act as a censor and suppress the news of any heretical discoveries. The symbol of the Magisterium is an Insignia of the Holy Church, its abbreviation is V.E.S.O. (One Church Over All). The abbreviation probably came from Latin 'Una ecclesia super omnibus'.
