Long ago, when I taught media and culture classes at Denver Seminary, I had a large bulletin board in the lobby outside the auditorium on which I pinned all kinds of items from the mainstream press.
This wasn't a current events board. Instead, my goal was to show the seminary community that all kinds of things were happening in the world around them that raised questions that were essentially moral and theological in nature.
There was, for example, a newsweekly cover about female anger and the movie "Thelma and Louise." I wasn't suggesting that pastors show video clips from this R-rated drama. My point was that the controversy swirling around it was important -- especially for people whose churches were involved in divorce-recovery ministry.
Mostly, I was trying to get seminary people to tune in, whenever the culture talks about ultimate questions. Hang on with me for a minute, because this is taking us into the pages of GQ and that feature story called, "The Love Song of Robert Bentley, Alabama's Horndog Governor."
Here is a piece of a book chapter from that time, explaining this "signal" concept:
I believe that our media are constantly sending out "signals" that can help the church go about its ministry and mission work in this post-Christian culture. Sadly, the church and our seminaries are ignoring both the content and social role of popular culture mass media, which are among the most powerful cultural forces in the modern world.
So what is a "signal?" I have defined this as a single piece of media or popular culture focusing on a subject that is of interest to the church. It can be a newspaper article, a single episode of a television show, a compact disc, a movie, a new video, a best-selling book or some other specific item.
Thus, a prime "signal" is when the mass media raise crucial questions, even if their proposed answers are less than adequate, from the church's point of view.
