In order to understand why so many evangelicals recently support left-leaning political causes, it is important to know a little history. In the 1970s, many campus radicals raised in Christian homes brought neo-Marxist ideas from college back to church with them. At first, figures like Jim Wallis, Ron Sider, and Richard Mouw made great gains for their progressive evangelical cause. But, after the defeat of Jimmy Carter, the religious right stole the headlines.

Today, a new crop of mainstream evangelicals has taken up the cause of the New Left whether they know it or not. As pro-life evangelicals rush to support movements like #BlackLivesMatter and #MeToo, it is important to realize they are walking in footprints already laid down. Their mission may be more successful, but it is not new. To understand where the evangelical social justice movement is heading, it is vital to understand the origins of the movement.
