Weary of Southern Baptists’ dominance in American Protestantism, a new push is starting by other Baptist groups aimed at working on social justice issues and showing their religious tradition is broader than the conservative SBC. President Carter is leading the effort.

More than 10,000 moderate and liberal Baptists are expected for three days starting today in Atlanta for the “Celebration of a New Baptist Covenant.” Organizers aren’t forming a new denomination, but want to develop common ministries that would have a big impact.

Mr. Carter, a longtime Bible teacher at his Plains, Ga., church, hopes the event will “solidify the image of Baptists and Christians being able to cooperate with other.”

“We’re not going to delve into past divisions,” Mr. Carter told the Associated Press. “We’re going to try to show we can work in harmony.”

The meeting is taking place just days before February 5, when 24 states hold delegate-rich presidential primaries and caucuses. Baptists organizers say the timing is coincidental; they began planning the Atlanta event about two years ago before the primary schedule was set. “This has not anything to do with Super Tuesday,” Mr. Carter said.

Yet the biggest Baptist names at the event are prominent Democrats. Along with Mr. Carter, major speakers include Vice President Gore and President Clinton, who has played a leading and provocative role in the presidential race of his wife, Senator Clinton. Senators Graham of South Carolina and Grassley of Iowa, both Republicans, will also address the meeting. A former Arkansas governor, Mike Huckabee, a Southern Baptist minister and GOP candidate for president, had agreed last year to participate, then canceled. “Even with Senators Grassley and Graham and some token Republicans, I think it’s going to be viewed, especially by lots of folks in the Southern Baptist Convention, as a Democratic gathering,” a professor at South Carolina’s Furman University who studies religion and politics, James Guth, said. “Mr. Clinton is still too controversial a figure to be a neutral arbiter.”

Conservatives waged a long, vicious campaign for control of the Southern Baptist Convention in the 1970s and ’80s to wipe out any moderate or liberal thinking in seminaries, churches, and Baptist agencies. A retired Texas judge and one of the leaders of the purge, Paul Pressler, famously said conservatives were “going for the jugular” for the cause.

With 16.3 million members, the denomination is not only the largest American Baptist group but also the largest Protestant group in the country. SBC leaders were asked to participate, but convention president Frank Page said last year, “I will not be part of any smoke screen left-wing liberal agenda.” Mr. Page issued a more conciliatory statement last week, after Mr. Carter contacted him to explain the gathering.

“I continue to be concerned as to at least some participants’ motives for this event,” Mr. Page said. “However, I have assured President Carter of my prayers for this meeting.”

The 30 groups joining the new covenant effort say they represent millions of Baptists. Among them are historically African-American Baptist denominations, which produced many civil-rights leaders, including the Reverend Martin Luther King Jr.

“This is an opportunity to correct what should have happened long ago,” said the Reverend William Shaw, president of the National Baptist Convention USA, Inc., the largest black Baptist group. Northern and Southern Baptists split in 1845, when Northerners said they wouldn’t support missionaries who were slaveholders. African-American Baptists generally formed their own denominations, and had their own splits over civil-rights strategies and other differences. The groups meeting in Atlanta span a range of beliefs on theological and political issues and have diverse styles of worship. Many oppose abortion and gay marriage, and several groups only ordain men.

However, they also heavily emphasize Bible teaching on social justice. The gathering will spend a significant amount of time discussing poverty, health, and other policy concerns, along with talks on preaching and the Gospel.
