I remember little, but I suppose I'll try to help. Some of the main points I remember that were made were the differing priorities that the Asa Geats and Danes had compared with the obviously Christian poet who later re-wrote the original poem into the epic we now know as Beowulf. The Geats and the Danes at the time valued martial prowess very highly, war and accomplishments in war and phsyical activities were considered important. Men depended on the strength of thier steel, thier weapons, and thier skill. By contrast, Christianity places alot of emphasis on putting dependence on God and his providence.
Faith is what carries the day, rather than arms.
Look for example at how Beo is able to defeat Grendel bare-handed, using the strength supposedly given to him by God, while the other warriors are helpless against the Monster, becuase they depend upon thier steel. At least, this is the analysis that my teacher gave us. I think, though, that you have to look at it more carefully. Constantly conquering, pillaging, making war. And no, I'm not Asa.
