Like many of our readers, I have been digging into tons of coverage of the new Pew Forum study (full .pdf document here) offering an update on the growth of the "nones" and the cultural-left coalition of religious liberals, agnostics, atheists, "spiritual but not religious" believers and simple unaffiliated people.

As our own Julia Duin noted the other day, the basic theme in the mainstream coverage is that the number of self-proclaimed "Christians" in America is falling, quickly. That's a totally valid, if a rather old and much-reported story.

Also, I noted another old story, which is the fact that the number of religious believers who say they are actively PRACTICING their faith seems to be rather stable. The numbers are level in some pews, slightly down in some (think Southern Baptists), way down in others (think liberal Protestantism and cultural Catholics) and actually rising in a few (think Pentecostalism). The importance of growing ministries to Latinos, African-Americans and Asians is another news story, at the moment.

This was, as you would imagine, the subject of this week's "Crossroads" podcast. However, after host Todd Wilken and I talked -- click here to tune that in -- it hit me that there is another way to frame this debate. In part, Christian leaders are arguing over whether churches grow when they are (a) culturally modernized and less doctrinally demanding or (b) when they hold firm to ancient doctrinal standards and, in many ways, reject trends in the modern world. Then, after that, it hit me that many modern churches -- think evangelical megachurches -- seem to be striving to look and sound modern, while claiming to stay orthodox at the level of morality and doctrine. So that is, kind of, a (c) approach, in their eyes.
