A day before Pope Francis was to arrive in New York, Mayor Bill de Blasio and Cardinal Timothy M. Dolan said on Wednesday that a partnership between the Roman Catholic Church and the city would provide 150 beds this winter to homeless people who have been living on the street.

Mr. de Blasio said the effort, part of a recently announced initiative with religious organizations, would honor the pope’s visit.

“Pope Francis is calling us all to action,” Mr. de Blasio said at a news conference outside St. Anthony’s Church in the Bronx.

New York City’s effort to expand work with religious groups is one of several steps the city has taken in recent weeks to address the issue of homelessness, and it comes a day after Los Angeles declared a state of emergency and pledged tens of millions of dollars in additional funding to deal with the estimated 26,000 people who live on its streets.
