Carl Trueman tackles two pressing questions: What constitutes an evangelical, and has this individual lost all rational thought? Trueman's verdict is that modern evangelicals have sacrificed theology on the altar of experience and activism, resulting in a hazy, doctrine-starved mindset. This has led to a bizarre scenario where figures as diverse as Joel Osteen, Brian McLaren, and John MacArthur are all lumped together under the evangelical umbrella. Fifteen years ago, historian Mark Noll sounded the alarm in The Scandal of the Evangelical Mind, lamenting that evangelicals had relinquished their intellectual heritage, leaving them ill-equipped and disinclined to engage in intellectual debates, and thus relegated to the cultural fringes. Trueman argues that today, religious beliefs are more scandalous than ever – but for reasons that diverge from Noll's prognosis. The real issue now is not that evangelicals lack intellectual rigor, but that they can no longer agree on the essence of the gospel. Despite being known as champions of the gospel, evangelicals have lost a unified understanding of its meaning. Trueman's incisive critique of evangelicalism also offers a roadmap for theologically conservative Protestants to reclaim their heritage and forge a better path forward.
