Harry S. Truman on the United States as a Christian Nation in an Exchange of Messages with Pope Pius XII
August 28, 1947
An enduring peace can be built only upon Christian principles. To such a consummation we dedicate all our resources, both spiritual and material, remembering always that except the Lord build the house, they labor in vain who build it. [...T]he valiant pioneers who left Europe to establish settlements here [...] declared their faith in the Christian religion and made ample provision for its practice and for its support. The story of the Christian missionaries who in earliest days endured perils, hardship—even death itself in carrying the message of Jesus Christ to untutored savages is one that still moves the hearts of men. As a Christian Nation our earnest desire is to work with men of good will everywhere to banish war and the causes of war from the world whose Creator desired that men of every race and in every clime should live together in peace, good will and mutual trust.
