Here is an interesting piece about Bart Campolo, who is the new Humanist Chaplain at the University of Southern California. Campolo is a former evangelical Christian and the son of Tony Campolo, the famous evangelical preacher.
The whole point of theologically progressive Christianity is that Christianity is not about turning people into Christians, or even making sure that they stay Christian. It's about the same thing that Bart is about. It's about love, and creating communities of love. If Bart can spread this love without Christian or any other religious content, I will holler a hearty hallelujia! His way is a good way, just as my way is a good way.
People are different. What works for some does not work for others. For those of us who love the myth and poetry and music and art and legacy of selfless service of Christianity, liberated from irrational and suffocating dogma, there will always be a home in progressive Christian communities. For those looking for communities offering the same kind of loving support, but without the religious language, what Bart is creating may be the answer. We share a common cause reached through different means. And we have a lot to learn from each other.
