The late Lyle E. Schaller was always popular with journalists because he had the rare ability to dig deep into statistics and demographics, while speaking in direct-quote friendly language. But it was always hard to know what to call him. He was an expert on church-growth trends. But he was also a United Methodist. Wait for it.

Schaller used to laugh whenever he was called a “United Methodist church-growth expert,” in part because of that flock’s serious decline in membership over the past quarter-century or more. If he was a church-growth pro, why didn’t his own denomination listen to him? It was something like being an expert on Baptist liturgy, Episcopal evangelism or Eastern Orthodox praise bands.

But when Schaller talked about the future, lots of people listened. Check out this material from a column I wrote about him entitled, “United Methodists: Breaking up is hard to do.”

One side is convinced the United Methodist Church has cancer. The other disagrees and rejects calls for surgery. It's hard to find a safe, happy compromise when the issue is a cancer diagnosis. …

So it raised eyebrows when United Methodism's best-known expert on church growth and decay called for open discussions of strategies to split or radically restructure the national church. Research indicates that United Methodists are increasingly polarized around issues of scripture, salvation, sexuality, money, politics, multiculturalism, church government, worship and even the identity of God, said the Rev. Lyle E. Schaller of Naperville, Ill.

Many people are in denial, while their … church continues to age and decline, he said, in the Circuit Rider magazine for United Methodist clergy. Others know what's happening, yet remain passive.

Sports fans, That. Was. In. 1998.

Schaller told me that he was basing his diagnosis on the open doctrinal warfare that began two decades earlier, in the late 1970s. He was very familiar with a prophetic study that emerged from Duke Divinity School in the mid-1980s, entitled “The Seven Churches of Methodism."

Do I need to say that Schaller’s words are highly relevant in light of the acid-bath drama in yesterday’s final hours at that special United Methodist conference in St. Louis (GetReligion posts here and then here)?

But this is old news, really. Activists on both sides of this struggle have been doing the math (see my 2004 column on that topic) for four decades.
