Explain Golding's use of the following leterary devices using evidence : Allusion

One of the major points of debate between critics who have studied Lord of the Flies is the significance of the substantial number of allusions to Judeo-Christian mythology. While many scholars have argued that these references qualify the novel as biblical allegory, others have suggested that the novel's allusions to the Old and New Testaments turn out to be ironic and thus criticize religion. A careful reading of Lord of the Flies should take into account not only the abundance of biblical images and themes in the text, but also the ways in which religion and religious themes are used. The concept of the Beast, for example, is an allusion to Revelations of the New Testament:

And I stood upon the sand of the sea, and saw a beast rise up out of the sea (Revelations 13:1)

This, of course, can be directly linked with Chapter 5 Beast on the water.
