The United Nations opened a month-long conference in New York this week to review ways to contain the spread of nuclear weapons. Prior to the conference, leaders from several religious traditions gathered at an interfaith chapel across from the UN to pray for the abolition of all nuclear weapons. Christians, Jews, Muslims, Buddhists, and others offered prayers, chants, songs, and special readings. Watch excerpts of the service, where some of the participants included Buddhist peace activists; Roman Catholic Archbishop Joseph Mitsuaki Takami of Nagasaki, Japan, a survivor of the 1945 atomic bombing, who brought a scorched piece of a statue of Mary from the cathedral that was destroyed in the attack; a Shinto chant leader; Rev. Michael Kinnamon, general secretary of the National Council of Churches; a Native American prayer-song leader; Buddhist and Muslim readers; and Bishop Katharine Jefferts Schori, presiding bishop of the Episcopal Church.
