Subsequently, the Newsweek report simply confirms the fact that, just as Christendom has died in Europe and the major American cities, it is now dying in the suburban and rural areas of America as well. With the social benefits of professing to be a Christian no longer in place and the social stigma of not professing to be a Christian now lifted, those who were part of Christendom America are simply no longer pretending to be part of Christian America.
Since those who professed faith but did not practice faith were confusing to account for, this is actually a good thing. Now, it is more likely that if someone is a Christian or non-Christian, he or she will state so plainly.
Therefore, the number of Christians has likely not diminished as much as has been reported, but rather we are seeing an increasingly accurate accounting of actual Christian America. The ARIS study confirmed this by saying that the number of people who claimed to be Christians decreased, while the number of people who claimed to be evangelical increased. This fact is not discouraging, but rather clarifying.
Mark Driscoll has an article posted at Fox News that attempts to differentiate Christendom in America from Christianity in America. It is a good article for Driscoll fans and non-fans alike as it is completely free from any theological argumentation. Here is a quote that I think is clarifying for those who are afraid our 'Christian Natin' is disentegrating.
