There's been a recent spat of articles on the "new atheism" and what that challenge represents in terms of religious faith. These include Karen Armstrong, John Spong, and Miroslav Volf . They all focus on the way that small conceptions of God need to be broken down.
"The choice between the theism of the church and the atheism of those who reject the God of the church is to me a sterile and lifeless choice. Such a meeting between believers and atheists might lead us to examine what Paul Tillich called “the God beyond the gods of men and women.”- John Spong
Some other sites: The progressive Christian radio show I help put together with some friends now has a website. We'll be posting podcasts of the show in the future so check it out. Also adding a Disciples of Christ pastor's site that includes some good pieces on society and the church.
