During the recent weeks of Lent, the Rev. Ryan Bell has led his Southern California congregation into the penitential spirit of the season. He has preached about the prophet Isaiah’s admonition “to loose the bonds of injustice.” He has replaced his church’s ebullient praise songs with somber, reflective music. He has sent his members a list of ordinary comforts to give up until Easter, with suggestions from caffeine to Facebook.

And Mr. Bell has committed his congregation to one other religious obligation. He is withdrawing the church’s money, several hundred thousand dollars, from its account with the Bank of America. By the April weekend when Christians mourn Jesus’ crucifixion and celebrate his resurrection, Mr. Bell said, he will have moved the assets to a local bank as a protest against Bank of America’s role in mass foreclosures and to issue a call for its repentance.

“To right the wrongs of the world is as much a part of the Lenten experience as to repent ourselves,” Mr. Bell, 40, the pastor of Hollywood Adventist Church near Los Angeles said in a phone interview this week. “During this season, when we individually are examining our lives, we think it’s appropriate for the institutions that affect us to examine theirs.”

Across the country, dozens of other clergy members and congregations have taken similar action over the past three years. Beginning with two ministers in a bedroom suburb outside Oakland, the movement has grown to encompass about 25 congregations, according to the PICO National Network, a coalition of congregations involved in social justice that has taken up the campaign. By PICO’s estimate, congregations have withdrawn $16 million, and their individual members and organizational partners an additional $15 million, from banks deeply implicated in the foreclosure crisis — primarily Bank of America, Wells Fargo and JPMorgan Chase.
