- Simon's encounter with the Lord of the Flies resembles a temptation or demonic revelation, revealing that evil comes from within human beings.
- The island echoes the Garden of Eden, transforming from an apparent paradise into a place corrupted by human sin.
- The "beast" symbolizes the inner sinful nature of humanity rather than an external monster.
- Themes of temptation, the Fall, sin, sacrifice, and moral corruption run throughout the novel.
- The novel contrasts innocence with humanity's fallen condition, a central biblical theme.
