OT: From the Email Box

I received this email in response from Stu to my recent post on Kate Gregory:

Hi,

Slightly off topic, but you use the term "fight the good fight" in your post about Kate on 12/26/05.

I've heard that phrase before. Can you please tell me where that phrase comes from?

Thanks.
Stu

When I think about it, I have to admit that I'm not sure where it comes from or where I first heard it and picked it up. I did an MSN web serarch on the phrase and it looks like most of the results relate to politics and/or religion. I most likely didn't pick it up from any of those sources.

The most likely source that I got it from is the movie Titan A.E.:
