The Rev. Robert Jeffress of the First Baptist Dallas Church Choir introduces President Donald Trump during an event at the Kennedy Center for the Performing Arts in Washington in July. Some of Trump's leading evangelical supporters defended him after his controversial remarks about immigration.

NEW YORK — Donald Trump’s vulgar remarks questioning why the U.S. should admit immigrants from Haiti and Africa have spotlighted the bitter divide among American evangelicals about his presidency.

While some of his evangelical backers expressed support for his leadership, other conservative Christians are calling the president racist and say church leaders had a moral imperative to condemn him.

“Your pro-life argument rings hollow if you don’t have an issue with this xenophobic bigotry,” tweeted pastor Earon James of Relevant Life Church in Pace, Fla.

Trump won 80 percent of the white evangelical vote in the 2016 election. But recent polls show some weakening in that support, with 61 percent approving of his job performance, compared with 78 percent last February, according to the Pew Research Center.

Still, conservative Christians remain as polarized as ever over his leadership.

Many evangelical leaders who defended him in the past would not comment on Trump’s remarks to a group of senators. A few offered some criticism. Pastor Ronnie Floyd, a former president of the Southern Baptist Convention, said it was “not good” to devalue any person.

Johnnie Moore, a public relations executive and a leader among Trump’s evangelical advisers, said the reports of what Trump said were “absolutely suspect and politicized.”

Sen. Dick Durbin, D-Ill., who attended the Oval Office meeting Thursday, and peopled briefed on the conversation said Trump did make the comments as reported: He questioned why the U.S. would accept more immigrants from Haiti and “shithole countries” in Africa as he rejected a bipartisan immigration deal.

Sen. Lindsey Graham, R-S.C., who Durbin said objected to Trump’s remarks at that time, did not dispute Durbin’s description.

Pastor Mark Burns from South Carolina remained skeptical, but said if the remarks were true, Trump was only reacting to poor conditions in Haiti and Africa that were the fault of “lazy governments” there.

The Rev. Robert Jeffress, pastor of First Baptist Dallas and a frequent guest at the White House, said that apart from the president’s choice of words, “Trump is right on target in his policy,” putting the needs of the U.S. above those of other countries.

Yet anger spread among other conservative Christians.

They posted family photos on social media and proudly noted immigrant relatives. Bishop Talbert Swan of the Church of God in Christ, or COGIC, the country’s largest black Pentecostal denomination, tweeted a photo of one of his grandchildren born to what Swan said was his “educated, hard-working” Haitian-American daughter-in-law.

A significant number of African immigrants are Christians who joined U.S. evangelical congregations, and many have become advocates for more generous immigration policies.

Thabiti Anyabwile, pastor of Anacostia River Church, a Southern Baptist congregation in Washington, said his church includes Christians from Rwanda, Nigeria, Guyana, Cameroon and Zimbabwe.

Evangelicals are aware of a geographical shift in global Christianity. As its numbers shrink in North America and Western Europe, the Christian population is exploding in Africa, Asia and elsewhere.

The Rev. Tish Harrison Warren, an Anglican priest who serves at The Church of the Ascension in Pittsburgh, worried about the fallout for the fellowship of evangelicals outside and inside the U.S. Her denomination, the Anglican Church in North America, was formed under the leadership of African Anglican bishops to serve conservative U.S. Episcopalians and others. Her local church includes parishioners from Uganda, Iran, Turkey, China and other countries.

“It hurts evangelism,” Warren said of the president’s comments.
