A leading voice of American Protestantism, Christian Century, strongly condemned the bombings. An editorial entitled "America's Atomic Atrocity" in the issue of August 29, 1945, told readers:
The atomic bomb was used at a time when Japan's navy was sunk, her air force virtually destroyed, her homeland surrounded, her supplies cut off, and our forces poised for the final stroke ... Our leaders seem not to have weighed the moral considerations involved. No sooner was the bomb ready than it was rushed to the front and dropped on two helpless cities ... The atomic bomb can fairly be said to have struck Christianity itself ... The churches of America must dissociate themselves and their faith from this inhuman and reckless act of the American Government.
A leading American Catholic voice, Commonweal, took a similar view. Hiroshima and Nagasaki, the magazine editorialized, "are names for American guilt and shame."
Pope Pius XII likewise condemned the bombings, expressing a view in keeping with the traditional Roman Catholic position that "every act of war directed to the indiscriminate destruction of whole cities or vast areas with their inhabitants is a crime against God and man." The Vatican newspaper Osservatore Romano commented in its August 7, 1945, issue: "This war provides a catastrophic conclusion. Incredibly this destructive weapon remains as a temptation for posterity, which, we know by bitter experience, learns so little from history."
