It's a long way from Storyline Fellowship in Denver's western suburbs to downtown Nashville and a publishing-and-ministry operation the locals have long called the "Baptist Vatican."

That's 1,165 miles, on a map. The cultural gap between the Colorado Rockies and Tennessee seems bigger than that.

Storyline Fellowship is the congregation that the Rev. Ben Mandrell and his wife, Lynley, started in their living room in 2014, helping it grow into a modern evangelical flock with 1,600 members in a revamped Walmart facility. That's the kind of challenge church planters accept when working as missionaries outside the Southern Baptist Convention's heartland in the Bible Belt.

Now the 42-year-old Mandrell has jumped from the SBC frontier into one of the most high-profile jobs in America's largest Protestant flock -- serving as the new president and CEO of LifeWay Christian Resources. That's the complex publishing, research and media company, with about 4,000 employees, that in simpler times as called the Sunday School Board.

Bible classes remain on the agenda, stressed Mandrell. But so are many other ministries that symbolize a new reality that all religious leaders will have grasp, one way are the other: The good old days of safe, predictable church work are gone.

"Not that we're not doing what we used to do" in terms of publishing materials used for Sunday Bible classes and other familiar forms of outreach, said Mandrell, in a telephone interview.

"But we're have to do so much more because America is getting so complex and diverse. … We have to keep asking our church leaders, 'What do you need us to provide for your tool boxes to do the work that you now know that you have to do?' "

This era of rapid change led to obvious changes -- including the series of explosions on January 6, 2018, that leveled the 12-story LifeWay tower, with its iconic giant stone crosses, that loomed over one corner of downtown Nashville. LifeWay moved to smaller, modernized facilities close to the Tennessee State Capitol.
