Dr. Albert Mohler responds to the study recently released by the Pew Forum on Religion and Public Life:
The most significant finding in this research may well [be] the documentation of the fact that the rise of the unaffiliated means that the “nones” are moving out of a loose religious affiliation into none at all.
In other words, those Americans who had previously reported a loose or tenuous identification with a religious body now feel free to identity with no faith at all. A casual faith is one that points to an individual moving out of any faith at all, rather than moving in. This strongly suggests that cultural Christianity, for example, is simply disappearing.
