I'm on the leadership board at my church, and the confluence of business and spirituality is an interesting phenomenon to me. Via Donald Sensing and Josh Claybourn, here's a fascinating Forbes Special Report on Christian Capitalism that investigates several different aspects of modern Christian churches, from the structure and history of "megachurches" to (generally awful) Christian video games. An excellent series of articles that I highly recommend to anyone interested in how churches look in the 21st Century.
There's a lot that can be said on this topic, but I don't think it's difficult to summarize my thoughts: Christian churches need to operate in the world, even though we aren't of the world. Methodologies and programs need to be malable and dynamic, even though the gospel of Christ is unchanging and the message remains the same. Using technology and business-savvy to spread God's Word is no different in spirit than when Jesus fed the crowds who came out to listen to him with fish and bread, or when he sent his followers out to the surrounding towns, two-by-two, to share his good news.
