Beowulfs story is somewhat of an allegory in which he is depicted as the Christ figure. The theme of Beowulf is a contrast of good and evil which is manifest in both Christian and pagan elements; Beowulf represents good, while Grendel, his mother, and the dragon represent evil. The first monster our hero, Beowulf, faces is Grendel. Grendel is said to be a descendant of Cain.
Unhappy creature (Grendel), he lived for a time in the home of the monsters race, after God had condemned them as kin of Cain (Norton, 28). Cain is the son of Eve, the woman who bore sin into the world. A connection, however vague, can be made between the maternal relations of Eve and Cain and Grendel and his mother. Grendels mother can be considered to personify mans fall from grace and Grendel himself might embody sin.
Furthermore, the dragon Beowulf battles can be said to be a picture of Satan: the smooth hateful dragon who flies at night wrapped in flame (56). When facing Grendel, Beowulf relies on God alone to protect him, saying, “may wise God, Holy Lord, assign glory on whichever hand seems good to Him (36). When Beowulf tears off Grendels arm, Hrothgar remarks, I endured much from the foe, many griefs from Grendel (39). It could be said that the Christian foe is sin, which causes much grief. Against Grendels mother, original sin, Beowulf becomes the Christian soldier. When Beowulf struggles against Grendels mother, God grants him a precious gift: The Wielder of Men granted me that I should see hanging on the wall a fair, ancient, great-sword most often He has guided the man without friends that I should wield the weapon (Norton, 48).
This great sword is further described as a victory-blessed blade, an old sword made by the giants the work of giants (Norton, 47). The sword used to slay Grendels mother is work of her ancestral giants, who were godly until they fell from grace. From (Cain) sprang all bad breeds, trolls and elves and monsters likewise the giants who for a long time strove with God (Norton, 28). Therefore, the sword was god-forged and godly. Here the hero is using the sword of the Spirit, which is the word of God to prevail (The Book of Ephesians 6.17, Bible). In his battle with the dragon (which may represent Satan) Beowulf is martyred, losing his life in the of the killing the dragon.
Beowulf is the Christ figure; the monsters are sin personified; and, moreover, the work Beowulf effectively becomes the sword of the Spirit and the word of God. It is important to note that, while there are many references to Cain, the devil, and God (Christian elements) there are also several mentions of fate and destiny, pagan elements. Beowulf believes in predestination and feels that destiny is mortally unchangeable, saying, Fate always goes as it must (33). This idea propels him into many battles even though the competition seems overwhelming. Yet, in apparent disregard for fate and destiny, Beowulf prays to God for help and thanks God for victory and protection.
