* The Novel's Focus: Golding's primary focus is on the nature of humanity and how civilization breaks down in the face of primal instincts. Religion, while a powerful force in society, is not central to the novel's themes.
* No Explicit Mention: There is no mention of Ralph's religious beliefs or practices in the book. We don't know if he's Christian, agnostic, atheist, or has any other specific religious affiliations.
* Possible Interpretations: Some readers might infer that Ralph's emphasis on rules, order, and reason suggests a certain adherence to the values of Western civilization, which are often rooted in Judeo-Christian traditions. However, this is speculation, and Golding doesn't provide any concrete evidence to support this.
* The Importance of Individuality: It's important to remember that the characters in "Lord of the Flies" are meant to be symbolic representations of human nature. Their individual beliefs and backgrounds, including their religious affiliations, are less important than the universal struggle between civilization and savagery.
In Conclusion: We cannot definitively say what Ralph's religion is. Golding intentionally leaves this aspect open to interpretation, focusing instead on the broader themes of the novel.
