So far this week, an anticipated nationwide sweep has not materialized at the expected magnitude. Yet the mere prospect of such action has prompted legions of pastors, rabbis and their congregations across the United States to stand ready to help vulnerable immigrants with offers of sanctuary and other services.

Here’s a look at some of the recent developments:

• • •

Rabbis have organized a network of more than 70 synagogues nationwide committed to supporting immigrants and asylum seekers, whether through providing sanctuary or other assistance, such as accompanying people to check-ins with immigration authorities.

Some rabbis have been arrested during a series of protests organized by Jewish activists to oppose immigration crackdowns, including a demonstration Tuesday at the headquarters of Immigration & Customs Enforcement in Washington.

The network — T’ruah: The Rabbinic Call for Human Rights headquartered in New York City — says it represents more than 2,000 rabbis and cantors.

“I’ve never seen an issue that has so mobilized the Jewish community all over the country — it’s reached a breaking point,” said T’ruah’s director of organizing, Rabbi Salem Pearce. “A lot of our families went through the things immigrants are experiencing today.”

Baltimore-based Lutheran Immigration and Refugee Service, which has been assisting uprooted people since 1939, has launched a United Sanctuaries of America campaign, seeking to recruit places of worship willing to provide sanctuary to anyone fearful of deportation without due process. LIRS also is reaching out to community organizations and nonprofits which would help ensure that sanctuary providers have needed resources such as legal assistance and logistical support.

“The response has been incredible,” said LIRS president Krish O’Mara Vignarajah. “Churches are saying they want to be part of this — some have offered to provide safe spaces or meals. Some who have existing sanctuary spaces are now saying they need the legal services.”

ICE considers churches and some other places to be “sensitive locations” and generally does not pursue people inside who are seeking sanctuary.

In Seattle, the Gethsemane Lutheran Church provided sanctuary for more than a year for a Mexican immigrant, Jose Robles, who was targeted for deportation. On Wednesday, Robles — accompanied by his wife and three daughters, Gethsemane’s pastor, and dozens of other supporters — presented himself to an ICE office in a Seattle suburb, where he was detained after applying for a stay of deportation.

Robles’ fate is uncertain. The pastor, Joanne Engquist, said efforts would continue to get him a U-visa that would enable him to avoid deportation.

Of course, we are deeply disappointed in the outcome,” Engquist said. “What keeps us going is hope for justice.”

At the Church of the Epiphany in Los Angeles, Father Tom Carey says housing people in the sanctuary is an “option of last resort.”

Carey is a member of an organization called Clergy and Laity United for Economic Justice, or CLUE, which advocates for low-income families and immigrants. Ahead of the announced raids, eight Christian congregations publicly offered their buildings as sanctuaries through the organization.

Even in his sermons, Carey takes a stance. By chance, this week’s reading was the story of the good Samaritan.

“According to the parable that Jesus told, our neighbors are not the people we know. Our neighbors are the people we don’t know who are in trouble,” Carey said. “And the commandment is to love your neighbor.”

Carey’s church also connects immigrants needing legal help with an immigration lawyer who works pro bono. Of his 70 or so congregants, Carey estimates a third are in the U.S. illegally.
