The Christian faith must be born again, says one prominent pastor. And to be born again, Christians must be unlocked from "a prison" of long-held assumptions and have the freedom to ask honest questions, Brian McLaren indicates in his newest book, A New Kind of Christianity. He's not advocating for a new set of beliefs, he says, but rather a "new way of believing."

Today, after serving as a pastor for more than 30 years, he often sees picketers and leaflets labeling him as "dangerous," "controversial" and "unbiblical" when he visits churches around the world to speak. He wonders, "How did a mild-mannered guy like me get into so much trouble?"

"They're very satisfied with their theology as it is," McLaren told The Christian Post. But he's not. Hence, the quest for a new kind of Christianity.

"Some people seem to believe that all of those [theological] interpretations are easy and clear, that their church or denomination has nailed them down or figured them out. And I just don’t think it’s that simple," McLaren said.

But he insists he hasn't moved away from certain Christian truths such as the deity of Christ and the authority of Scripture. But he does have some qualms over the "inerrancy" of Scripture. "The word 'inerrancy' never occurs in Scripture and my concern with inerrancy is that it brings into our discussion about the Bible a set of philosophical assumptions that aren’t really necessary and actually can be unhelpful and counterproductive," he commented to The Christian Post.

He believes a lot of Christians read the Bible as a legal constitution. "[I]n many religious settings, there are no checks and balances, and challenging an authority figure's interpretation can lead to excommunication," he writes in his book. "At least good constitutions can be amended."

Perhaps his main argument against traditional Christianity is what he calls the "Greco-Roman narrative" – or the "unspoken" story line that many Christians hold to. It consists of six lines: Eden, fall, condemnation, salvation, heaven or hell/damnation. It's the six-line narrative that he feels serves as the glasses by which many Christians see everything with. McLaren questions the entire narrative, including the fall or "original sin" and hell.
