I just came up with the idea to include a little column called "Preacher's Corner" in my church newsletter, which says:
"The following works of art, literature, contemporary non-fiction, film and Scripture are likely to be referenced at length in upcoming sermons."
And then I list them. They include Amadeus, Equus, "Brokeback Mountain," Antigone, the Gospel of Matthew, the book of Genesis (4:1-16), King Lear, The Cambridge Platform, of 1648 Picasso's "Guernica" and Michaelangelo's "Pieta." I think, gee, this is kind of cool. I might like to hear these sermons myself.
Now, I can do this because I actually have planned a bunch of sermons for the spring. I don't know how far in advance I'll be able to do this in the future. But I think my church will dig it for a few reasons: first, it might get a few more people reading the newsletter, second, it gives them a chance to think about things before I use them in sermons, and third, it shows in black & white that there's a whole world out there for your serious religious reflection, so go ye and theologize!
