(RNS) Tony Campolo, a progressive evangelical leader who counseled President Bill Clinton through the Monica Lewinsky scandal, announced Tuesday (Jan. 14) that the organization he founded nearly 40 years ago will close on June 30.

Campolo, 78, plans to retire with the closure of the Evangelical Association for the Promotion of Education, but he will continue to write and speak, with nearly 200 engagements scheduled for 2014. He said his health is fine and he wants to write one more book on how Christianity fits with the social sciences...

Campolo and other progressive evangelicals like Ron Sider and Jim Wallis have taught evangelicals how to speak the language of social justice, said David Swartz, a history professor at Asbury University and author of the book “Moral Minority: The Evangelical Left in an Age of Conservatism.”

In the 1970s, evangelicals often emphasized personal holiness and salvation, Swartz said. “Campolo’s biggest legacy is to reinsert social holiness into the evangelical imagination,” Swartz said.
