How To Find Common Ground When You Disagree About the Common Good

This essay is the first installment of a new weekly series by Christianity Today.

How do Christians live faithfully and as good neighbors in a world we don’t control?

In 2020, Tim Keller and I coedited a book titled Uncommon Ground. Our project convened a group of evangelical and evangelical-adjacent friends to reflect—as the subtitle said—on how Christians can live faithfully in a world of difference. Since then, however, I’ve rephrased the question for my own work. We should be faithful, yes, but also neighborly. And our world is not just host to real difference of belief; it’s also a world we don’t control.

I owe this subtle but important reframing to my friendship and work with Eboo Patel, the founder and president of Interfaith America. The most important interfaith organization in the country, Interfaith America does not advance a soupy multiculturalism that pretends that all roads lead to heaven or that our differences don’t matter. It takes religious particularity seriously, identifies conflicts and tensions created by that particularity, and works to find common ground across religious differences.

Interfaith engagement that doesn’t devolve into a soupy multiculturalism is difficult—and necessary in our diverse democracy.

I met Eboo nearly a decade ago. On that first meeting, we talked about the challenges of having young kids, busy travel schedules, and public writing commitments, as well as the importance of interfaith cooperation. Since then, we’ve spoken, taught, written, and built together.

As a Muslim, Eboo does not believe in the saving work of Jesus Christ—and that difference between us is no small thing. We have other differences too: Eboo tells more stories than I do. I drink alcohol, and he doesn’t. His language is usually more colorful than mine. We are friends in spite of our differences.

What does this kind of friendship have to do with Christian engagement in the world? Almost everything.
