Bishop Oscar Cantu of Las Cruces, New Mexico, also called on President Barack Obama to strengthen the legal prohibitions against torture "to ensure that this never happens again."

The bishop joined several religious leaders who condemned the use of torture by the CIA after Democrats in the Senate released a 500-page executive summary of the Senate Select Committee on Intelligence findings Dec. 9. The full 6,000-page report remains classified.

The comments were provided by the Washington-based National Religious Campaign Against Torture after the report became public.

The intelligence committee began investigating the CIA's treatment of detainees in the so-called war on terror almost six years ago. Committee members adopted the report in 2012 and agreed to release it in April, but Senate Democrats waited eight months to do so.

The report slammed U.S. tactics, which critics have described as torture, used against detainees. It said some of the tactics were more brutal than first described, produced little information that prevented an attack and often resulted in "fabricated" information.

Sr. Patricia Chappell, executive director of Pax Christi USA, said she was appalled by the "lack of moral integrity of a nation and individuals who justify the use of torture in the name of national security." She called the actions by the CIA a "travesty of justice and a flagrant violation of human rights, with no reverence for the dignity of human life."

Gerry Lee, executive director of the Maryknoll Office of Global Concerns, said the report should drive Congress to enact new laws to permanently prevent the use of torture.

"Maryknoll missioners have very often served in communities alongside torture survivors, and some have experienced torture themselves," he said. "As Christians, they know that it is horrific, dehumanizing behaviour and its use must be stopped immediately."

Scott Wright, director of the Columban Centre for Advocacy and Outreach, said torture is never justified, adding that the report "makes very clear that crimes were committed, laws were broken and lies were told to the American people by our government. We must never as a nation go down that path again."

The acts of torture described in the report "are not just horrific," but also represent a "brutal violation of our country's most basic values," said Matt Hawthorne, policy director for the National Religious Campaign Against Torture.

With the report's release, the United States can begin healing "from self-inflicted spiritual wounds," he said.

"The revelations about the use of torture have been a source of torture to many of us," said Sayyid M. Syeed, national director of the Office of Interfaith and Community Alliances of the Islamic Society of North America. "We had taken pride in the fact that we have left behind many societies where it was a norm and that we had chosen to be part of a nation that prided itself on its belief in human dignity and human rights."

The Rev. Susan T. Henry-Crowe, general secretary of the United Methodist Church, General Board of Church and Society, concluded that the report's findings "shock the conscience." She called for actions that respect life as a gift from God in condemning any government-sanctioned practices that violate moral teachings.
