On the Tuesday after the election, two dozen pastors gathered in the back room of a Lower Manhattan church to begin plotting the resistance. Most of the faith leaders were immigrants, and all of them members of the New Sanctuary Coalition of New York City, an interfaith network of congregations, organizations, and activists. Since its founding in 2007, the coalition has worked on the front lines in the fight to protect undocumented New Yorkers from detention and deportation.

The meeting began with a prayer—“We pray you will give us all the right to remain in justice, in solidarity and in truth”—delivered by a soft-spoken Mexican priest, first in Spanish, then in English. Updates from the past week followed—reports of congregations in crisis, sleepless nights spent consoling worried parents, tearful children afraid to go to school. The mood was tense but focused, and before long they’d arrived at the main item on the agenda.

“We are here today to discuss the future of physical sanctuary,” said coalition director Ravi Ragbir, a towering Trinidadian immigrant who once spent two years in immigration detention over a wire fraud conviction. Since his release, he’s managed to avoid deportation through prosecutorial discretion, though he fully expects to be among the first targets of the upcoming raids. “It’s time for us to start thinking more radically.”

Since it emerged nine years ago, the coalition has acted in two distinct capacities. Publicly, they advocate for the city’s undocumented residents, lobbying for reforms while hosting legal clinics and solidarity events. Many of the group’s best known actions, like their monthly prayer walk around Federal Plaza to protest deportations, fall into this category. The second capacity, called physical sanctuary, is more discreet. Premised on the quasi-legal expectation that federal agents will not raid houses of worship, physical sanctuary is the act of secretly housing immigrants facing deportation. Sometimes the tactic is used to provide a temporary safe haven during an overnight raid, while other times it involves housing an immigrant for months as they await a court ruling. At least eleven Christian congregations in the city currently offer physical sanctuary.

The purpose of the meeting, Ragbir explained, was to begin thinking about how to expand the number of congregations dramatically before Donald Trump takes office. “We need to reach out to every group in this city, to every representative,” he said. “We need faith leaders to step up and show their support for physical sanctuary, because the present situation is only going to get worse.”

The present situation, Ragbir noted, is that the United States is currently expelling immigrants at a rate unprecedented in history. Under Obama, at least 2.4 million immigrants have been deported—a 21 percent jump from the previous record, held by George W. Bush. And these raids aren’t just happening in border states, like Arizona and Texas. Just a few weeks before the election, Immigrations and Customs Enforcement (ICE) agents rounded up 25 undocumented workers during a raid on four restaurants in Buffalo. Such workplace sweeps were especially common during the Bush years, and as the legal director of the New York Immigration Coalition recently told The New York Times, the model may serve as a blueprint for the coming administration.

Should President Donald Trump decide to ramp up deportations—as he has repeatedly promised—there’s very little the rest of the government could do to stop him. While he’ll need funding from Congress to increase the size of ICE, there are currently 14,000 ICE officers, agents, and special agents already in place. In the past, only a fraction of those officers have worked on tracking down undocumented immigrants, but a single memo from President Trump could reshape the focus of the agency overnight.

The gathered faith leaders were painfully aware of the human cost of such an amped-up deportation regime. They know firsthand what it’s like to lose members of their community to ICE sweeps—to watch a parishioner banished to Mexico, forced to leave behind her two children, Michel and Heidy, ages nine and 13; to see a Haitian father of four sent to an immigrant detention center for a twenty-year-old drug conviction. In some cases, the coalition has blocked these measures by working through the available legal channels. In others, a more creative approach has been necessary.

“Our number one job right now is protect people,” Donna Schaper, minister at Judson Memorial Church and a founder of the New Sanctuary Coalition, told the group. “We’re about to enter a new, more radical phase of this movement. We need to get organized, fast.”

And so that’s what they did. For the next ninety minutes, the faith leaders deliberated on their fast-approaching future. “How do we make sure a person can find us at 5 a.m. when ICE descends on their neighborhood?” asked one pastor. “What are the minimum necessities my church needs in order to offer physical sanctuary?” asked another. And finally, the question on so many people’s lips: “What is the single most important thing we need to do next?”

Two days after the meeting, Ravi Ragbir stood in the basement of a different lower Manhattan church, addressing another circle of weary faces. About forty undocumented immigrants sat in silence before him, a mix of first-timers and long-serving members of the New Sanctuary Coalition. The goal of the meeting was to provide a different sort of sanctuary—a venue for the community to, in the words of one activist, “be part of a movement that creates spaces where people can live in dignity.”
