Goldsmith, Margaret E. “The Christian Theme of Beowulf.” parklandsd.org. Go.Galegroup, November 16, 2011. Web. September 17,2015.
The main purpose of this work is to illustrate that although Christianity is dominant throughout Beowulf, it is wrong to see Beowulf as "Christ-like." Goldsmith indicates, to other critics and readers of Beowulf, that there are heavy Christian parallels such as Beowulf acting as a savior in reference to Christian knights/Christ, but Beowulf isn't a "perfect" enough model to represent Christ, since Beowulf has some flaws that take away from that. This is relevant in that it gives insight into Beowulf's character and helps unveil his weaknesses to readers, despite him being posed as a noble hero. There is little to no bias in this criticism, for everything was logically explained.

This work’s main purpose is to show that Grendel’s mother has a 2 sided character, one being human and one being demonic, and one portraying female aspects such as being motherly but also portraying male aspects such as being ferocious, seeking revenge with a fight, and not being passive. The author goes on to explain that her contradictory nature sheds light on the common theme of revenge seen in the story, and helps explain the contradictory and simultaneous presence of satisfaction and pain when it comes to blood feud/revenge.
