The Pilgrim's Progress, a 1678 Christian allegory by John Bunyan, follows the spiritual journey of protagonist Christian from the "City of Destruction" to the "Celestial City," symbolizing salvation. Its complex narrative, rich in symbolic challenges and ethical conflicts, has inspired a wide range of interpretations.
James Anthony Froude commended its universal appeal, noting its ability to transcend sectarian boundaries, while Robert Louis Stevenson praised its emotional depth. James Baldwin observed its declining popularity in modern times, yet the work's lasting influence stems from its ability to reflect humanity's search for meaning, connecting theological teachings with enduring existential themes.
