But the problems of race and poverty in America “still require the highest caliber of attention,” said Mr. Edgar, who cited the flawed government response to New Orleans and its mostly poor, black population after Hurricane Katrina. He said he was distrustful of the Justice Department’s leadership to make appropriate decisions as to the nation’s civil rights priorities.

A New Mission

Some critics say that many of the Justice Department’s religious-oriented initiatives are outside its mandate from Congress. While statutes prohibit religious discrimination in areas like employment and housing, no laws address some of the issues in which the department has become involved.

“They are engaging in freewheeling social engineering,” said Ayesha Khan, counsel for Americans United for Separation of Church and State, and “using the power of the federal government to put in place an ideological, not constitutional agenda.”

The department declined to make available for interviews Assistant Attorney General Wan J. Kim, who heads the civil rights division, or Eric Treene, who holds the newly created position of special counsel for religious discrimination.

Ms. Magnuson, the Justice Department spokeswoman, said it was justified in devoting so much attention to the issue because Congress has demonstrated its interest by including religion in the landmark Civil Rights Act of 1964 and enacting the 2000 law involving zoning restrictions, the Religious Land Use and Institutionalized Persons Act.

Ms. Magnuson also said the department had not diminished its interest in enforcing racial and national origin discrimination cases. The changes at the Justice Department began under Attorney General John Ashcroft, but have accelerated under Alberto R. Gonzales, his successor.

Mr. Gonzales has increasingly cited his agency’s record on behalf of religious causes as among his most important accomplishments, often noting the successful intervention in cases on behalf of people who had suffered discrimination for wearing Muslim head coverings. In speeches, he routinely says that religious freedom is the nation’s “first freedom because our founders saw fit to place it first in the Bill of Rights.”
