When teaching courses on biblical studies, I have often enjoyed opening a class with a popular song that draws on an expression from a biblical text. For this purpose, I have made use of Mark McEntire and Joel Emerson's Raising Cain, Fleeing Egypt, and Fighting Philistines: The Old Testament in Popular Music (Macon: Smith & Helwys, 2006) and Angela Pancella's collection of biblical reference in U2's lyrics at atu2.com. While very useful, these collections are of course limited in scope. Here I provide the means to collaboratively produce a much more comprehensive collection of biblical allusions in popular music.
Of course, there are recording labels that specifically target a Christian audience, and although many songs distributed by these labels are full of biblical allusions, my main interest here is in collecting songs with which students in a secular university may be familiar.
