Anyone looking for Baptists should head to Greenville, S.C.

"People here say you can throw a rock in one direction and hit a Southern Baptist church and if you throw a rock in the other direction you'll hit an independent Baptist church," said Nathan A. Finn, provost of North Greenville University.

Finn's school -- with strong Southern Baptist ties -- isn't the only brand of "Baptist" life in town. There's the progressive Furman University, as well as the independent Bob Jones University, known for its rock-ribbed Baptist defense of fundamentalism.

The Baptist world is extremely complex and hard for many outsiders to navigate. Some of this confusion, said Finn, affects life inside the most prominent Baptist flock -- the Southern Baptist Convention -- and perceptions of SBC conflicts.

"Lots of people need to understand that Southern Baptists are far more diverse, ethnically and culturally, than they think we are," he said, in a telephone interview. "At the same time, we're more uniformly conservative that we often appear, especially since we spend so much time fighting with each other over some of the small points of theology on which we differ."

With some of these stereotypes in mind, Finn recently fired off a dozen Twitter messages describing different images of real "Southern Baptist" churches that are common today. The goal, he said, was to create "composites of what different kinds of SBC congregations look like" and he gave them "names that are common with certain types of real churches."

There is, of course, a "First Baptist Church" which Finn described as "a downtown church that runs 500 in worship. The church is affluent, which is reflected in their beautiful building. The worship service is traditional. There are lots of programs & committees" and the congregation is known for big donations to the SBC's shared "Cooperative Program" budget.

Then there is one of the megachurches that have dominated the American religious marketplace in recent decades. While the word "Baptist" is missing in its name, Finn noted: "CrossWay Church is a suburban church that runs 1400 in two services. The 'feel' of each service is laid back & contemporary. CrossWay has excellent recreational facilities" and its leaders are "considering launching a second campus."

These big churches frequently make headlines.
