Religious groups are pushing back against a wave of opposition toward Syrian refugees and are working to preserve the United States as a haven for those fleeing their war-torn nation.

“We’re really in emergency mode,” said Jen Smyers, director of policy and advocacy for the Immigration and Refugee Program at Church World Service, one of the nine U.S. nonprofits that work with the federal government to resettle refugees.

“We’re talking to the media nonstop. We are sending letters and petitions and making phone calls to all the governors, as well as to members of Congress right now,” she said. “Every voice is needed to make sure they understand just how important the resettlement program is.”

The Refugee Resettlement Program program — which relies mostly on faith-based organizations to find homes, jobs and schools for refugees — is under attack, a casualty of the Islamic State group’s assaults on Paris on Nov. 13 that killed 129 people and wounded hundreds of others.

Arguing that the federal government can’t assure that terrorists from Iraq and Syria, where ISIS makes its headquarters, won’t gain entry to the United States through the program, American politicians have sought to curb it and, by extension, the work of its religious partners. In the wake of the carnage in France:

• More than 30 governors, almost all Republican, have said they would not accept Syrian refugees into their states, although the authority to admit refugees lies with the federal government.

• Several Republican presidential candidates — including Ben Carson, Donald Trump, Ted Cruz and John Kasich — have denounced President Obama’s efforts to resettle more Syrian refugees.

• A new NBC News/SurveyMonkey online poll shows that 56 percent of Americans also want to ban Middle Eastern refugees from the United States.

• The U.S. House of Representatives approved a bill Nov. 19 that would make it extremely difficult for any Syrian or Iraqi refugees to enter the United States. President Obama has promised to veto the legislation, which the Senate likely will consider after its Thanksgiving break.

These latest developments on Capitol Hill have the nonprofits particularly worried. The resettlement program in recent years has annually welcomed between 70,000 and 80,000 people to the United States, with about 2,200 from Syria since 2011. Just weeks ago, they had high hopes that those numbers would increase.

Mounting numbers of Syrians, faced with civil war and terrorist threats at home, were boarding flimsy boats to escape and then drowning in the Mediterranean. A widely circulated photo of a dead Syrian toddler, washed up on a Turkish beach, tugged at many American hearts. President Obama said in September that the United States would increase the number of Syrians it would accept to 10,000 in the coming year.

Then the Paris attacks happened, ISIS announced that it would target New York and Washington, and news reports raised the possibility that one of the Paris bombers may have entered Europe amid a group of refugees. American politicians began lashing out against plans to bring more Syrians to America.

“What the political backlash has done is build a climate of fear, and for some people it is based in Islamophobia,” said Rabbi Jennie Rosenn, vice president for community engagement at the HIAS, formerly known as the Hebrew Immigrant Aid Society, one of the nine faith-based groups supporting the resettlement program.

“We’ve been very quickly mobilizing our whole network, our network of Jews, our network of communal leaders and our network of rabbis to take action,” she said.

They have been asked to explain to their representatives in Congress, Rabbi Rosenn continued, “that the resettlement process shutting down would be antithetical to everything we believe as Jews and everything that America stands for as a refuge for vulnerable people.”

Six of the nine nonprofits that work with the program are faith-based, and guided by the biblical injunction to welcome the stranger. In addition to HIAS and CWS, they are: The United States Conference of Catholic Bishops, Lutheran Immigration and Refugee Service, Episcopal Migration Ministries and World Relief.

In recent days, these groups have sent their leaders to Capitol Hill, hoping to derail the House bill and dissuade the Senate from supporting a similar measure.

They have hosted webinars and conference calls with their clergy and lay leaders, as Episcopal Migration Ministries did Nov. 19 and Nov. 23 to encourage sermons and local efforts to counter hostility toward the refugees.

And they have reached out to the media, to remind the public of the plight of the Syrians, and to reassure that the U.S. government carefully vets everyone accepted under the program.

“Let’s remember these refugees themselves are fleeing ISIS,” Linda Hartke, president of Lutheran Immigration and Refugee Service, told a Wisconsin television station last week after Gov. Scott Walker of Wisconsin announced that the state would not help resettle any Syrians. 

Terrorists won’t use the resettlement program to gain entry to the United States, she said, because it takes so long and scrutinizes them so carefully — a sentiment repeated by many who work with refugees in the United States.
