Once upon a time, Southern Baptists in Bible Belt communities knew how to talk to people who didn't go to church.

"We were dealing with people who were, for the most part, like us," said Baptist historian Nathan Finn, the provost of North Greenville University, located in the South Carolina hills near the North Carolina border. "Everyone understood sweet tea, fried chicken and SEC football. It was easier to talk to those people about Jesus."

Things changed, as the greater Greenville-Spartanburg welcomed waves of high-tech firms and industries with global brands such as BMW, Bosch, Fluor, Hitachi and many others. Today's newcomers speak German or Japanese.

"It's not Black folks and White folks from the South. We're past that. The Sunbelt has gone global and we're more urban. We don't know how to talk to the new people," said Finn. "The cultural gaps are bigger. … Southern Baptists are better at handling these kinds of issues in foreign missions than in our own communities."

Finn has been studying this trend and others for years, which led him to write a series of articles in 2009 for Southeastern Baptist Theological Seminary entitled "Fifteen Factors that have Changed the SBC since 1979."

Anyone who knows Southern Baptist Convention history gets that 1979 reference. That was when activists backing "biblical inerrancy" attacked establishment leaders of America's largest Protestant flock, while also supporting causes favored by the surging Religious Right. Electing one SBC president after another during the 1980s, this "conservative resurgence" helped change the face of evangelicalism.

There are signs a second Baptist civil war may be ahead.
