Has been a long time since ive read beowulf, but I know that during this time there was missions taking place to convert angles and evangalize england/the angles. most likely they were establishing benedictine monastaries. I would look for line and page numbers that discuss interactions with monks/monastaries and people on missions converting the anglo saxons; the role that God (God of christinaity) plays in peoples lives is usually that they fear him and want to please him and do things to attain salvation. Not sure if in beowulf god is God of christianity or a god in general or a different kind of god.
