"The Church of Jesus Christ of Latter-day Saints condemns violent words and actions and affirms its commitment to furthering peace throughout the world. Speaking of the Mountain Meadows Massacre, Elder Henry B. Eyring, then a member of the Quorum of the Twelve Apostles, stated, “The gospel of Jesus Christ that we espouse abhors the cold-blooded killing of men, women, and children. Indeed, it advocates peace and forgiveness. What was done here long ago by members of our Church represents a terrible and inexcusable departure from Christian teaching and conduct.”'46
