WASHINGTON — Prominent Christian, Jewish and Muslim leaders held an extraordinary “emergency summit” meeting in the capital on Tuesday to denounce what they called “the derision, misinformation and outright bigotry” aimed at American Muslims during the controversy over the proposed Islamic community center near ground zero.

“This is not America,” said Cardinal Theodore E. McCarrick, the emeritus Roman Catholic archbishop of Washington, flanked by three dozen clergy members and religious leaders at a packed news conference at the National Press Club. “America was not built on hate.”

They said they were alarmed that the “anti-Muslim frenzy” and attacks at several mosques had the potential not only to tear apart the country, but also to undermine the reputation of America as a model of religious freedom and diversity.

The imam behind the plan to build an Islamic center near ground zero, Feisal Abdul Rauf, finally spoke out about the controversy, saying in an opinion piece in The New York Times published Tuesday night that he would proceed with plans to build the center. He wrote that by backing down, "we cede the discourse and, essentially, our future to radicals on both sides."
