Then came the 2016 election.

Black congregants — as recounted by people in Chicago, Los Angeles, Atlanta, Fort Worth and elsewhere — had already grown uneasy in recent years as they watched their white pastors fail to address police shootings of African-Americans. They heard prayers for Paris, for Brussels, for law enforcement; they heard that one should keep one’s eyes on the kingdom, that the church was colorblind, and that talk of racial injustice was divisive, not a matter of the gospel. There was still some hope that this stemmed from an obliviousness rather than some deeper disconnect.

Then white evangelicals voted for Mr. Trump by a larger margin than they had voted for any presidential candidate. They cheered the outcome, reassuring uneasy fellow worshipers with talk of abortion and religious liberty, about how politics is the art of compromise rather than the ideal. Christians of color, even those who shared these policy preferences, looked at Mr. Trump’s comments about Mexican immigrants, his open hostility to N.F.L. players protesting police brutality and his earlier “birther” crusade against President Obama, claiming falsely he was not a United States citizen. In this political deal, many concluded, they were the compromised.

“It said, to me, that something is profoundly wrong at the heart of the white church,” said Chanequa Walker-Barnes, a professor of practical theology at the McAfee School of Theology at Mercer University in Atlanta.

Early last year, Professor Walker-Barnes left the white-majority church where she had been on staff. Like an untold number of black Christians around the country, many of whom had left behind black-majority churches, she is not sure where she belongs anymore.

“We were willing to give up our preferred worship style for the chance to really try to live this vision of beloved community with a diverse group of people,” she said. “That didn’t work.

It is hard to reconcile a vote for Trump with racial harmony.
