Pilgrim's Progress was written in two parts, in 1678 and 1684, by the English Puritan preacher, John Bunyan. It tells the story of a pilgrim, named Christian, who abandons his wife and family for a journey from the City of Destruction to the Celestial City. His adventures are related with humor and satire which has accounted for the novel's enduring appeal. Despite its tone, Bunyan's message is didactic; although Christian survives the inducements of Mr. Worldly-Wise and Vanity Fair, to name two, ultimately he is not allowed to enter the Celestial City. To the Puritans, a spiritual journey alone did not guarantee salvation.
