Pollsters need to start asking more detailed questions about American Catholic life

Theology news rarely sends shock waves through Catholic offices around the world, but this headline did: "Just one-third of U.S. Catholics agree with their church that Eucharist is body, blood of Christ."

The key word in that famous Pew Research Center survey was "transubstantiation," which the report defined as the belief that the "bread and wine used for Communion become the body and blood of Jesus Christ."

It mattered, of course, whether the Catholics in this survey went to Mass. Nearly 70% of self-proclaimed Catholics said the consecrated bread and wine were mere "symbols," but 63% of those who reported weekly Mass attendance affirmed transubstantiation. Insiders noted that this meant that 37% of observant Catholics didn't embrace this crucial church doctrine.

"Any effort to measure human behavior is fraught with peril and complications," noted John C. Green of the University of Akron, reached by telephone. A trailblazer in studies of politics, pulpits and pews, Green has often served as a Pew Research consultant.

"If people say they go to Mass once a week, how certain can you be that they're telling the truth? … When it comes to doing surveys about what believers say and what they do, you can never ask too many questions."

Now, as Catholics prepare for a new pope, Pew has released new insights into lines of tension and division among American Catholics. Five years after the "transubstantiation" study, a new survey includes more evidence that "U.S. Catholics" disagree with many core Catholic doctrines and, thus, want a "more inclusive" church.

The tricky question, again, was how to define "U.S. Catholic," since the survey said:

Has the DNA of Southern Baptist Convention doctrine changed on ordaining women?

After decades as America's most famous Sunday school teacher, Jimmy Carter decided to cut the symbolic ties binding him to the Southern Baptist Convention.

The former president remained active at Maranatha Baptist Church in Plains, Georgia, and didn't renounce his faith. His 2000 letter to 75,000 American Baptists explained that he rejected a revision of the SBC's Baptist Faith and Message document, months earlier, to oppose the ordination of women.

"I have been disappointed and feel excluded by the adoption of policies and an increasingly rigid SBC creed," wrote Carter, who is now 98 years old and in hospice care. He stressed that, with his wife Rosalynn, he would cooperate with "traditional Baptists who share such beliefs as separation of church and state, servanthood of pastors, priesthood of believers, a free religious press, and equality of women."

From Carter's point of view, the SBC had evolved from a convention of autonomous churches -- with individuals claiming "soul competency" when choosing their own beliefs -- into a denomination that defines orthodoxy on doctrines.

The issue isn't who is a Baptist and who is not. Church historians struggle to count the number of organized Baptist groups and thousands of Baptist churches are totally independent. The question is whether the SBC's DNA has changed in ways that will affect local churches, as well as agencies, boards and seminaries at the state and national levels.

The Rev. Rick Warren -- an American evangelical superstar -- urged the recent national convention in New Orleans not to "disfellowship" congregations that ordain women, such as the giant Saddleback Church he founded in 1980.

"For 178 years, the SBC has been a blend of at least a dozen different tribes of Baptists," said Warren, during floor debates. "If you think every Baptist thinks like you, you're mistaken. What we share in common is a mutual commitment to the inerrancy and infallibility of God's Word, and the Great Commission of Jesus.

"No one is asking any Southern Baptist to change their theology. I am not asking you to agree with my church. I am asking you to act like a Southern Baptist -- who have historically 'agreed to disagree' on dozens of doctrines in order to share a common mission."
