Writing in "Skeptic" magazine, Michael Shermer contrasted such practices with mainstream religions: "Envision converting to Judaism but having to pay for courses in order to hear the story of Abraham and Isaac, Noah and the flood, or Moses and the Ten Commandments. Or imagine joining the Catholic Church but not being told about the crucifixion and the resurrection until you have reached Operating Theological Level III, which can only be attained after many years and tens of thousands of dollars in church-run courses."
