 Also contrasting in "Doctor Who" are the explicit examples of destiny and theism in the narrative, presented by the characters of the Black Guardian and White Guardian (both of whom are apparently representatives of an even higher power) and the Beast, who claims to have been imprisoned by a group called the 'Disciples of the Light,' a name that echoes traditional Christian and Zoroastrian theology.Although "Torchwood" has an existentialist view of life, there are several pointed moments with Christian symbolism.In one episode Captain Jack offers himself as a sacrifice to a satan figure to save the world, and his loyal followers wait faithfully for his resurrection.
