Actually, Black Elk was baptized as a Roman Catholic in about 1915 about 18 years before the famous book. Surely the author knew that since Black Elk was a lay Catholic missionary to the Sioux from the time of his baptism to his death in about 1945 as a 1990s biography revealed. When that biography was written, Black Elk's surviving daughters were quoted in the New York Times Book Review as expressing gratitude that his Catholicism had been recognized.
