In the 1930s McPherson and the Foursquare Gospel Church explored Pacifism, a component of Pentecostalism. McPherson also considered Gandhi's views on pacifism, and Clinton Howard, chairman of the World Peace Commission, was invited to speak at the Temple. In 1932, she promoted disarmament. Foursquare leaders, alarmed at rapid changes in military technology, drew up an amendment inclusive of varied opinions on military service. Two views were held acceptable: the idea that one could bear arms in a righteous cause; and the view that killing of others, even in connection to military service, would endanger their souls. McPherson monitored international events leading up to the Second World War, believing that the apocalypse and the Second Coming of Christ were at hand.
