The collapse of one disastrous form of Christian social engagement should be an opportunity for the emergence of a more faithful one. And here there are plenty of potent, hopeful Christian principles lying around unused by most evangelicals: A consistent and comprehensive concern for the weak and vulnerable in our society, including the poor, immigrants and refugees. A passion for racial reconciliation and criminal justice reform, rooted in the nonnegotiable demands of human dignity. A deep commitment to public and global health, reflecting the priorities of Christ’s healing ministry. An embrace of political civility as a civilizing norm. A commitment to the liberty of other people’s religions, not just our own. An insistence on public honesty and a belief in the transforming power of unarmed truth.
