Defining Religion

Reading Deitrick's article about religion and how it means different things to different people and how it is sort of an amorphous concept has caused me to doubt that a definition of religion is very useful. However, since I am a religious studies major and I'm graduating this spring it seems like I should have some definition of religion handy. If some one asks me what I got my degree in and I tell them religious studies, and they ask me "How would you define religion?", it would seem pretty silly if I could not answer. I guess I could go the route where I say that I don't think there is any one definition of religion and that it is a loose cluster of concepts, but I will still need to describe what I think religion is before I'm done. It is probably best if I come up with some quick definition of religion that is satisfactory to me, if for not other reason than to be prepared to spit it out if I'm ever asked. So I guess I need to come up with one before this semester is over.
