Christopher Catherwood [grandson of David Martyn Lloyd Jones], The Evangelicals: What They Believe, Where They Are, and Their Politics (Wheaton: Crossway, 2010), 27, 71–72, 76:

This . . . is the major divergence between evangelicals and other Protestants: we still hold to those two Reformation truths of sola fide and sola scriptura . . . .

Who Are Evangelicals?

For many readers who might not know any professing evangelical Christians, the answer to this chapter’s question might seem a simple
one, if what you see in the newspapers is any guide. An evangelical is a white, middle-class male Republican from the southern part of the United States (or, as we now have to add, a white female Republican from the rural West of America).

Now, for sure, many evangelicals would indeed fit into this description, and they are the demographic about which the mainstream news media writes the most. But, in truth, this description presents a highly misleading picture, and also a dangerous one, as it confuses evangelicalism as a whole, which is a worldwide, global movement, with just a tiny segment of it, and gives it a political coloring that is utterly atypical of evangelicals in most countries today. For it is now widely said that the average evangelical is an economically poor black Nigerian woman with numerous family members suffering from HIV/AIDS.

So wrong gender, wrong skin color, wrong country, wrong social class—in fact wrong everything when it comes to the stereotype of evangelicals we commonly see on television or in the newspapers. For the fact is that the overwhelming majority of evangelical Christians today do not live in the West at all but in what most commentators refer to as the Global South, or the Two-thirds World, since most of the world live there. . . .

[I]t is now true: African Christians are more typical of twenty-first-century Christianity—and, I would add, of evangelical Christians—than those in the now predominantly secular West.
