Chaferian vs Reformed Sanctification

Never posted a discussion topic before, but here it goes... I have been pondering the various views of sanctification held by those in our circles (I hold the Reformed view), and I have some questions. I must admit that I have read little on the subject, yet have no time to do so at the moment. Therefore, I seek to draw on your knowledge and input (Chris, I know that have studied and hold the Chaferian view, so your help is appreciated). This is a list of questions that have popped into my brain:

*What are the distinctive points/ideas in the Chaferian model?
*Is the Chaferian model simply the Keswick model with a vocabulary makeover?
*What exactly is a "carnal Christian" by Chafer's definition?
*What exactly is a "spiritual Christian" by Chafer's definition?
*How and when does a carnal Christian become a spiritual Christian?
*Once a carnal Christian becomes a spiritual Christian, can he revert to being a carnal Christian?
*What are the Scriptural evidences of said understanding of carnal/spiritual Christianity?
*Do you believe that the idea of "carnal Christian" and the Reformed model are mutually exclusive?

Again, I ask these questions having very little understanding of the Chaferian view. I appreciate any efforts made to clarify this issue for me.
