Example:
During an interview with the Monty Python troupe in 1979, they professed that "Life of Brian" was a condemnation of closed systems of thought. Example: after Brian escapes from the Romans, he is followed by a group of people who mistakenly believe he is the Messiah based on the fact that he does not finish his statement and therefore is "mysterious" to them. When he tells them he is not the messiah, they claim that only the true messiah would deny this. That is where dogma comes in. In the early stages of their new religion, Brian's unlikely followers built their faith out fo whole-cloth. They recover a gourd that is briefly owned by Brian, proclaim that it is a holy artifact and begin to assign greater meaning and significance to it. Upon finding his shoe, a schism emerges among his new followers. They are instantly dedicated to the emerging dogma to the religion of Brian. They are so eager to believe in Brian as the messiah that they immediately begin fashioning the tenants of their faith; the dogma of their religion.
