This list of the "top 50 most influential Christians" is interesting, less as a genuine guide for influence (many of these people are TV media types, hence explaining their influence) and more as a reflection of who is "Christian." For example, I didn't realize that some of these people would self-identify as "Christians"--especially, Dr. Phil and Sean Hannity.
Still, in terms of a simple ranking, how in the world is John Piper (#24) and Rob Bell (pastor, Mars Hill Church, outside of Grand Rapids, MI; #25) ranked ahead of Pope Benedict XVI (#44)? I would think that the 1 billion Roman Catholics worldwide would disagree! And even before he became pope, Ratzinger was hugely influential in the life of the Roman Catholic Church.
