Although a parish might offer sanctuary, it does not obligate federal agents to respect church property boundaries, he said.

"With separation of church and state, the church really does not have the right to say, 'You come in this building and the law doesn't apply to you.' But we do want to say we'll be a voice for you," the cardinal explained.

Cardinal Wuerl said that providing food and legal representation for immigrants was among the Washington Archdiocese's top priorities.

Elsewhere, Cardinal Blase J. Cupich of Chicago told priests and school officials in the archdiocese not to allow federal immigration agents onto church property without a warrant in a Feb. 28 letter.

He asked parish and school officials to immediately call diocesan attorneys if agents appear at their door.

At the same time, Cardinal Cupich wrote that he will not declare Catholic churches as sanctuary for immigrants. The letter also restated archdiocesan policy that forbids anyone other than assigned priests to live in a rectory or other church facility without written permission of the appropriate regional vicar.

The situation of immigrants seems to have divided the country's Catholics. The majority of Catholics voted for Trump, according to polling data. However, bishops and leaders of Catholic nonprofit organizations have decried Trump administration policies regarding the suspension of refugee admissions to the U.S. and stricter enforcement of immigration laws even on people in the country for years.

Bishop Soto in his interview pointed to efforts in the 1980s by Catholic and Protestant churches to provide sanctuary for Guatemalans and Salvadorans who fled civil wars in their homelands for safety in the U.S. despite not being legally allowed in the country.

The Sacramento Diocese provides services to immigrants and refugees through its Diocesan Immigrant Support Network, which includes Bishop Soto, Catholic Charities, parishes, legal experts and community organizations.

About 60,000 immigrants who are not authorized to be in the U.S. live in the 20 counties of the diocese, according to a diocesan official.
