Here's a wierd newspaper article "Bishop Spong steps up fight against evangelism". I figure that the newspaper mistakenly failed to use the word evangelicalism. Evangelism is simply spreading the good news, a calling every church across traditions ought to be embracing. But the fact that evangelism and evangelicalism are seen as the same tells us much about how the mainstream media covers religion.
According to the article, "Evangelical churches, with their focus on the Bible as the infallible word of God have been growing for decades despite Spong's prediction that they would fade. None of this seems to faze Spong." But the issue is not whether evangelical bodies have grown. It's the fact that they are drawing from a smaller pool. The number of folks who have claimed non religion as their category has *doubled* since 1990.
As religion continues to be identified with particular set of conservative views, more and more people are unable or unwilling to identify with the Christian tradition. Spong is hitting on something that ought not be swept under the rug simply because the Southern Baptists added 1% or so to their rolls. By the way Spong was at a recent conference for spiritual progressives in CA. The Witherspoon Society has an article which covers that event.
