A little over three months ago, I shared “Beautiful Dark Things,” a piece of music along with an essay on drawing creative inspiration from nature. Sometime in September, I realized that the rhythm of that music fit well to the first half of Isaiah 60:1, “Arise, shine, Jerusalem; for thy light is come,” or in Latin, “Jerusalem surge illuminare, quia venit lumen tuum.” Cannibalizing a secular (or, as I often sense, just not overtly sacred) piece for use in sacred music is a venerable tradition. As Luther said, why should the devil have all the best tunes?

Not only did many Christmas hymns start out as secular carols, but even oratorios get in on the game. Handel repurposed several secular love duets for his Messiah. If you’re familiar with choruses from Handel’s Messiah such as, “For unto us a child is born,” “And he shall purify,” “His yoke is easy,” and “All we like sheep,” you’ll recognize them here. So, I’m in good company.
