The Voice of the Martyrs (VOM) is the name of several relate Christian organizations founded through the influence of Pastor Richard Wurmbrand in such countries as Australia, Canada, New Zealand, and the United States. These VOM missions raise awareness of the fact that hundreds of thousands are killed, tortured, imprisoned and harassed for being Christians each year. These organizations also provide practical assistance to persecuted Christians throughout the world. They are funded through donations and are not subsidized by government support. There is no world headquarters for The Voice of the Martyrs, as each organization is an independent, self-supporting entity. The American office of VOM is headquartered in Bartlesville, Oklahoma USA. The Canadian office of VOM is headquartered in Mississauga, Ontario, Canada.
