Still Evangelical?, a new book from InterVarsity Press, captures the way a certain segment of Christian leaders are thinking about this moment of evangelical identity crisis. All of the writers hold prominent positions in the worlds of ministry, seminaries, and religious advocacy, but none are household names outside of the Christian world. This is part of the point: Many highly respected evangelicals with significant influence are basically ignored by the mainstream press, creating a skewed view of what evangelicalism is.

Yet this group is also arguably at odds with many Americans who call themselves evangelicals. They write from elite perches. Many are unabashedly progressive, and at least one is a female executive pastor of a church—a controversial role for women in some evangelical denominations. Although some are bona fide conservatives, none seems to be a full-throated Trump supporter. For the most part, these are Christians who feel disoriented by their brothers and sisters who supported Trump in the election. That fact alone means they sit in the minority.

But these leaders are worth listening to for two reasons. First, as many of them write, they show the diversity of evangelicalism. Their stories add range and depth to an often flat portrait offered by the media. Second, their reflections on evangelicalism provide a road map of what may lie ahead. Each writer agitates for some kind of reform in churches and institutions; each sees the current state of affairs as unsustainable. If the term “evangelical” survives the turmoil of Trump—if, after everything, these Christians agree that they are “still evangelical”—his presidency may be looked back on as a crucible for change. Having redefined politics with evangelicals’ support, Trump may redefine expressions of evangelicalism as well.

Evangelicals are a notoriously difficult group to define. Many political exit polls determine who is evangelical by asking a single question along the lines of, “Do you consider yourself to be born again or evangelical?” This often confuses more than it clarifies: The answers may mix Protestants and Catholics together, obscure vast cultural differences among denominations, and downplay the distinctiveness of historically non-white churches. The most recent Pew Religious Landscapes survey goes into more depth, using “evangelical” as an umbrella term for churches and denominations that share certain convictions, practices, and origins. Pew puts their number in the U.S. around 62 million, a figure that includes people who identify as everything from Southern Baptist to Pentecostal to non-denominational.

Most of the writers in Still Evangelical? rely on a definition first published by the scholar David Bebbington in 1989, called a “quadrilateral” for its four distinctive qualities. According to Bebbington, evangelicals place the truth of the Bible at the center of their faith; they focus on Jesus’s atonement for sins on the cross; they emphasize a personal experience of conversion or salvation; and they believe they must actively share the gospel and do good in the world.
