The protests against President Trump’s policies since he took office have included marches of women, immigrants and scientists.

There was no march for people of faith. And yet, at every one of those other marches, large contingents of religious people joined in. They carried signs identifying their churches and synagogues, and often citing the scriptures that motivated them to participate.

The Rev. Jennifer Butler was among them. She is the chief executive of Faith in Public Life, a group in Washington that organizes leaders of many faiths to work together on politically liberal causes. The group is currently working on campaigns to preserve the Affordable Care Act and poverty programs, aid immigrants and refugees, promote gay and transgender rights, increase the minimum wage and address climate change.

She came to New York to talk with me about my recent story on the resurgence of the religious left under the Trump administration. The religious left is more diverse than ever before, including not just Christians but also Jews, Muslims, Sikhs, Buddhists and others.
